The metallic mandrel is pulled through a machine having rotating reels depositing the components of the

hose : bands of rubber, layers of textile or steel wires, metal spirals, bands of finishing tape. These reels

rotate both ways. The mandrels are then placed in 60-metre long autoclaves for vulcanisation. After exiting

the autoclave, the finishing tape is then removed and the mandrel extracted. This type of production

authorises the use of either metal or textile wires. It also allows the combination of one or more metal

spirals with textile plies and it is this same principle that wire-spiral high pressure hydraulic hoses are

manufactured. The minimum production quantity is 10 mandrels. Marking can be done either by transfer

or embedding.

The operator is placed on a trolley whose forward speed is controlled by mandrel rotation. He places the

different bands of rubber, layers of textile wires, metal spirals, bands of finishing tape, spirally wrapped.

This method of production gives great flexibility in the use of the various components of the hose. Marking

can be done either by transfer or embedding.

3.2 Production on manual and semi-automatic mandrels

This method of production authorises the manufacture of hoses with one or more textile or metal braids.

The mandrels are polyethylene with an internal steel wire. Marking can be done either by ink, embedding

or transfer. This method is usually reserved for hydraulic and brake hoses in diameters 3.2, 4.8, 6.3, 8, 9.5,

10, 12.7, 16, 19, 22, 25, 28, 32, 38.

3.3 Production on flexible mandrels

This method of production authorises extrusion of small bore hoses with a smooth finish (contrary to hoses

produced on mandrels which have a wrapped finish after being vulcanised under a tape wrapped around

the hose). Marking is done by ink or embedding.

3.4 Continuous production

Up-to-date equipment carries out the different operations necessary for the manufacture of a finished

product for hoses up to diameter 8” (200mm) : cropping, inner and outer skiving, handling, swaging,

testing, marking. The majority of end-fittings and ferrules are made in-house. A 22-metre traction and

hydrostatic test bench checks the reliability of the assembly.

This guide gives tecalemit rcmh recommendations relative to choice and conservation of elastomer hoses

and hose assemblies as much before as during use, in order to obtain maximum service life in optimal

safety conditions.

Moreover, tecalemit rcmh is at customers’ disposal for information concerning evolution of applicable

standards and rules.

Technical Guide

This technical guide is intended to help in selection, use and maintenance of TECALEMIT

RCMH elastomer hoses.

1. Introduction

A hose is comprised of 3 elements :

- The inner tube ensuring tightness is made from homogenous polymer presenting excellent resistance to

the conveyed product. It must have the best possible surface finish.

- The reinforcement gives the hose its physical and mechanical properties : resistance to both positive and

negative pressure, resistance to kinking, traction; this reinforcement can combine several technical

solutions to adapt to conditions of use : metal or textile braids or plies, metal or plastic spirals, cable plies,

electrical conductors. It also guarantees the dimensional stability of the inner tube thereby contributing to

tightness of the hose.

- The outer cover is made from homogenous polymer and intended to isolate the reinforcing structure from

the environment.

The function of a hose is to convey different solid, liquid or gaseous products either by suction or by

discharge. The large range of tecalemit rcmh flexible hoses responds to many diverse applications as these

are designed in a different way according to their use.

For the choice of an industrial hose, the user or prescriber should take a certain number of elements into

consideration.

These are extremely varied and have been classified into 7 main families :

- water (part N°s beginning with 1)

2. Hose structure

3. Selecting a hose

3.1 General criteria

3.1.2 Environment

3.1.3 State of conveyed product

By suction, under pressure or by gravity

3.1.4 Working method

Pressure and temperature of fluid, pressure surges, pressure peaks, frequency of use

3.1.5 Working conditions

Flexibility and ease of handling are considered and also :

- Imposed bend radius

- Vibrations of the system

- Applied traction

- Flexions

- Acceptable connections

3.1.6 Characteristics of use

These particularly concern the food quality of inner tubes, rules relative to the transport of dangerous

products, safety factors between pressure and burst pressures.

3.1.7 Standards and regulatory constraints

The inner hose diameter is without doubt the first citerion of choice.

Choosing too small a diameter provokes important pressure losses and an increase in fluid velocity

detrimental to hose service life in the case of abrasive products. Choosing too large a diameter gives way

to a needless increase in weight, size and cost of the installation and a reduction in ease of handling. This

diameter can depend only on the type of end-connection used, variable according to the application. This

diameter is often used to designate the hose.

(8)

Technical Guide

The outer diameter of the hose indicates its outer size. It is also necessary to know it in order to select

mounting devices and certain types of fittings.

3.3 Outer diameter (mm)

Expressed in bars by the abbreviations PS (pression de service - working pressure), PMS (pression

maximale de service - maximum working pressure), PMO (pression maximale d’utilisation - maximum

service pressure), WP (working pressure), PMA (pression maximale admissible - maximum admissible pressure).

TECALEMIT RCMH hoses are designed and manufactured for continuous service at the working pressure

indicated on each data sheet.

3.4 Working pressure

Expressed in bars by the abbreviations PE (pression d’épreuve - test pressure) or TP (test pressure)

The test pressure is very variable according to requirements of the applicable standards or those of the

customer.

Generally it is obtained by multiplying the working pressure by a safety factor (1.5 or 2 for example).

3.5 Test pressure

Expressed in bars by the abbreviations PLNE (pression limite de non-éclatement - pressure limit before

bursting) or BP (burst pressure.

The values indicated in TECALEMIT RCMH data sheets are those of the limit before bursting. they are

guaranteed for hoses before use and having been equipped with end-fittings in the preceeding month.

3.6 Burst pressure

The temperatures specified in tecalemit rcmh data sheets are the maximum admissible temperatures of

the hose for the fluid for which the hose is designed. Please consult our technical department for the use

of the hose with any other fluids.

Hoses may be used in different ambiant temperatures after having been priorly fitted with a heat-resistant

sheath, without which the hose outer cover would rapidly age, harden and become brittle.

3.7 Working temperatures

Expressed in millimeters, minimum bend radii are indicated by measuring at hose centre line, at maximum

working pressure and without hose flexion. In the case of a hose without internal metal spiral, it defines the

radius at which the hose may be rolled with a reduction of 15% of its internal section.

3.8 Bend radius

Any traction on a hose must be exerted in the centre line of the end-fittings. Only metal reinforced hoses

can reasonable support any off centre-line tractions. Tractions on suction hoses with metal spiral (helix)

must be avoided. They reduce working pressure and the internal section of the hose.

(9)

Technical guide

- Up to 3 years : use without restrictions

- From 3 to 6 years : make visual inspection. take samples and carry out hydrostatic test at twice working

pressure

- From 6 to 8 years : complete visual inspection. take sapmles and carry out destructive tests

- Over 8 years : do not use

All TECALEMIT RCMH hoses are marked with a date or number indicating date of production and date of

placing into stock.

The ideal storage temperature is 15°C and the acceptable range is from 0°C to +35°C. Hoses must not

therefore be placed near a source of heat. In all cases, stored hoses should not be subjected to

temperatures over +50°C or under -30°C. Moreover, large fluctuations in temperature during storage lead

to premature ageing of hoses. cracking caused by ozone increases with temperature.

4.3 Temperature

It is recommended to avoid relative humidity above 65%.

4.4 Humidity

Direct light is one of the main sources of ageing. in all cases, it is necessary to keep articles away from

sunlight or strong artificial lighting. should the storage area have large bay windows, these should be

covered with red, orange or white coating, or the items should be packed in an opaque wrapping.

4.5 Ultraviolet light

Ozone is an ageing factor which must be taken into account.

It is therefore necessary that storage areas are exempt of ozone generating equipment such as mercury

vapour lamps or spark-producing equipment such as alternative current electrical motors.

Also, the circulation of air around and inside the hoses should be limited, for example, by keeping the

original packing and plugging hose ends.

4.6 Ozone

Hoses should also be kept away from workshop areas where they could be exposed to projections of oil,

solvents, detergents or rodents.

4.7 Environment

Ozone is a major factor of aging which creates cracking in the rubber. When the hose is curved, the tension

exerted on the outer cover has a tendency to enlarge them. Consequently, the smaller the bend radius, the

more likely it is that cracking will appear.

4.8 Bend radius in storage

The principal to follow is to store hose in straight lengths, layed flat on supports, with

(10)

Technical guide

Should the hose be stored in reels, it is preferable to avoid stacking them in piles, as this could create a

permanent deformation of the hose.

Hoses should not be suspended on hooks and in general any flexions or tractions should be avoided.

During use a hose can be subjected to many effects which have not been forseeen. Obviously it is

recommended to use the hose in accordance with our indications concerning working pressure,

temperature, bend radius. In case of doubt, please contact our technical department.

5. Use and maintenance

5.1 Generalities

Hoses should be handled with precaution, they should not be dragged over sharp or abrasive surfaces, tied

in knots, trampled or flattened by vehicles.

5.2 Handling

It is preferable to consult our techical department for any use other than for which it has been designed.

Even so, a chemical compatibility chart according to the different types of elastomers comprising the hose

inner tubes of our range can be found at the end of this catalogue.

5.3 Products conveyed

Should the relative movement of the hose give way to a torsion, the end-fittings and/or connections should

be modified in such a way as to give flexion rather than torsion.

5.4 Torsion

It is advised to consult our technical department for any traction effects to which the hose may be subject,

as we are in a position to carry out traction tests.

5.5 Resistance to traction

Once per year, hoses should undergo visual inspection after cleaning with soapy water or

tensioactive-product based detergents. The hose must be rejected should any of the following defects be

revealed :

- Traces of leaks

- Ripped or torn outer cover

- Slipping of end-fitting

- Abrasion or slash revealing the reinforcement structure

5.6 Maintenance

Should the use be intermittent, that is used alternatively with steam and water following periods of cooling

for example, the innner tube is subjected to thermal shocks

5.7 Specific cases

(11)

Technical guide

leading to the phenomena of “pop-corning”, characterised by localised swelling. In effect, the steam

conveyed through the tube passes through the tube wall (it is for this reason that our hoses have their outer

covers micro-perforated to eliminate the build-up of gasses and avoid swellings). When the steam

circulation is interrupted or during the cooling phase, the steam condenses through the inner tube wall.

When the temperature increases, this water then vaporises again with an increase in pressure. The

alternating effects of these thermal shocks creating localised swellings, deteriorate the inner tube. In all

cases, the hose should be maintained in such a position as to prevent water from stagnating during halts.

It is obviously necessary to consult the chemical compatibility chart at the end of this catalogue, taking into

account temperature and concentration. In case of doubt, contact the technical department. It is

preferable to avoid stagnation of the product in the hose, particularly with regards to solutions or

emulsions as decantation can lead to concentrations above the admissible limits.

5.7.4 Hoses for corrosive or aggressive products

This particularly concerns liquid hydrocarbons, liquids or gases. Road transport rules impose a monitoring

sheet, which must be furnished by the manufacturer, with annual inspections and replacement after 6

years.

5.7.5 Hoses for inflammable products

Users must apply necessary rules concerning cleaning operations (usually with steam) and their frequency.

5.7.2 Hoses intended for food products

Abrasive products remove only a small part of the inner tube material in straight sections. Consequently,

abrasive product handling hoses should be maintained as straight as possible. In situations where bends

cannot be avoided, theses should have a radius as large as possible. Small radii give way to localised wear.

It is the same for sections reduced by an external force, where the abrasive product is accelerated.

It is also necessary to ensure good electrical conductivity in order to evacuate static electrical charges

produced by the rubbing of particles against the inner tube, otherwise leading to a perforation of the tube

wall.

The metallic mandrel is pulled through a machine having rotating reels depositing the components of the

hose : bands of rubber, layers of textile or steel wires, metal spirals, bands of finishing tape. These reels

rotate both ways. The mandrels are then placed in 60-metre long autoclaves for vulcanisation. After exiting

the autoclave, the finishing tape is then removed and the mandrel extracted. This type of production

authorises the use of either metal or textile wires. It also allows the combination of one or more metal

spirals with textile plies and it is this same principle that wire-spiral high pressure hydraulic hoses are

manufactured. The minimum production quantity is 10 mandrels. Marking can be done either by transfer

or embedding.

The operator is placed on a trolley whose forward speed is controlled by mandrel rotation. He places the

different bands of rubber, layers of textile wires, metal spirals, bands of finishing tape, spirally wrapped.

This method of production gives great flexibility in the use of the various components of the hose. Marking

can be done either by transfer or embedding.

3.2 Production on manual and semi-automatic mandrels

This method of production authorises the manufacture of hoses with one or more textile or metal braids.

The mandrels are polyethylene with an internal steel wire. Marking can be done either by ink, embedding

or transfer. This method is usually reserved for hydraulic and brake hoses in diameters 3.2, 4.8, 6.3, 8, 9.5,

10, 12.7, 16, 19, 22, 25, 28, 32, 38.

3.3 Production on flexible mandrels

This method of production authorises extrusion of small bore hoses with a smooth finish (contrary to hoses

produced on mandrels which have a wrapped finish after being vulcanised under a tape wrapped around

the hose). Marking is done by ink or embedding.

3.4 Continuous production

Up-to-date equipment carries out the different operations necessary for the manufacture of a finished

product for hoses up to diameter 8” (200mm) : cropping, inner and outer skiving, handling, swaging,

testing, marking. The majority of end-fittings and ferrules are made in-house. A 22-metre traction and

hydrostatic test bench checks the reliability of the assembly.

- The reinforcement gives the hose its physical and mechanical properties : resistance to both positive and

negative pressure, resistance to kinking, traction; this reinforcement can combine several technical

solutions to adapt to conditions of use : metal or textile braids or plies, metal or plastic spirals, cable plies,

electrical conductors. It also guarantees the dimensional stability of the inner tube thereby contributing to

tightness of the hose.

- The outer cover is made from homogenous polymer and intended to isolate the reinforcing structure from

the environment.

The function of a hose is to convey different solid, liquid or gaseous products either by suction or by

discharge. The large range of tecalemit rcmh flexible hoses responds to many diverse applications as these

are designed in a different way according to their use.

For the choice of an industrial hose, the user or prescriber should take a certain number of elements into

consideration.

These are extremely varied and have been classified into 7 main families :

- water (part N°s beginning with 1)

3.1.5 Working conditions

Flexibility and ease of handling are considered and also :

- Imposed bend radius

- Vibrations of the system

- Applied traction

- Flexions

- Acceptable connections

3.1.6 Characteristics of use

These particularly concern the food quality of inner tubes, rules relative to the transport of dangerous

products, safety factors between pressure and burst pressures.

3.1.7 Standards and regulatory constraints

The inner hose diameter is without doubt the first citerion of choice.

Choosing too small a diameter provokes important pressure losses and an increase in fluid velocity

detrimental to hose service life in the case of abrasive products. Choosing too large a diameter gives way

to a needless increase in weight, size and cost of the installation and a reduction in ease of handling. This

diameter can depend only on the type of end-connection used, variable according to the application. This

diameter is often used to designate the hose.

(17)

Technical Guide

The outer diameter of the hose indicates its outer size. It is also necessary to know it in order to select

mounting devices and certain types of fittings.

3.3 Outer diameter (mm)

Expressed in bars by the abbreviations PS (pression de service - working pressure), PMS (pression

maximale de service - maximum working pressure), PMO (pression maximale d’utilisation - maximum

service pressure), WP (working pressure), PMA (pression maximale admissible - maximum admissible pressure).

TECALEMIT RCMH hoses are designed and manufactured for continuous service at the working pressure

indicated on each data sheet.

3.4 Working pressure

Expressed in bars by the abbreviations PE (pression d’épreuve - test pressure) or TP (test pressure)

The test pressure is very variable according to requirements of the applicable standards or those of the

customer.

Generally it is obtained by multiplying the working pressure by a safety factor (1.5 or 2 for example).

3.5 Test pressure

Expressed in bars by the abbreviations PLNE (pression limite de non-éclatement - pressure limit before

bursting) or BP (burst pressure.

The values indicated in TECALEMIT RCMH data sheets are those of the limit before bursting. they are

guaranteed for hoses before use and having been equipped with end-fittings in the preceeding month.

3.6 Burst pressure

The temperatures specified in tecalemit rcmh data sheets are the maximum admissible temperatures of

the hose for the fluid for which the hose is designed. Please consult our technical department for the use

of the hose with any other fluids.

Hoses may be used in different ambiant temperatures after having been priorly fitted with a heat-resistant

sheath, without which the hose outer cover would rapidly age, harden and become brittle.

3.7 Working temperatures

Expressed in millimeters, minimum bend radii are indicated by measuring at hose centre line, at maximum

working pressure and without hose flexion. In the case of a hose without internal metal spiral, it defines the

radius at which the hose may be rolled with a reduction of 15% of its internal section.

3.8 Bend radius

Any traction on a hose must be exerted in the centre line of the end-fittings. Only metal reinforced hoses

can reasonable support any off centre-line tractions. Tractions on suction hoses with metal spiral (helix)

must be avoided. They reduce working pressure and the internal section of the hose.

(18)

Technical guide

- Up to 3 years : use without restrictions

- From 3 to 6 years : make visual inspection. take samples and carry out hydrostatic test at twice working

pressure

- From 6 to 8 years : complete visual inspection. take sapmles and carry out destructive tests

- Over 8 years : do not use

All TECALEMIT RCMH hoses are marked with a date or number indicating date of production and date of

placing into stock.

The ideal storage temperature is 15°C and the acceptable range is from 0°C to +35°C. Hoses must not

therefore be placed near a source of heat. In all cases, stored hoses should not be subjected to

temperatures over +50°C or under -30°C. Moreover, large fluctuations in temperature during storage lead

to premature ageing of hoses. cracking caused by ozone increases with temperature.

4.3 Temperature

It is recommended to avoid relative humidity above 65%.

4.4 Humidity

Direct light is one of the main sources of ageing. in all cases, it is necessary to keep articles away from

sunlight or strong artificial lighting. should the storage area have large bay windows, these should be

covered with red, orange or white coating, or the items should be packed in an opaque wrapping.

4.5 Ultraviolet light

Ozone is an ageing factor which must be taken into account.

It is therefore necessary that storage areas are exempt of ozone generating equipment such as mercury

vapour lamps or spark-producing equipment such as alternative current electrical motors.

Also, the circulation of air around and inside the hoses should be limited, for example, by keeping the

original packing and plugging hose ends.

4.6 Ozone

Hoses should also be kept away from workshop areas where they could be exposed to projections of oil,

solvents, detergents or rodents.

4.7 Environment

Ozone is a major factor of aging which creates cracking in the rubber. When the hose is curved, the tension

exerted on the outer cover has a tendency to enlarge them. Consequently, the smaller the bend radius, the

more likely it is that cracking will appear.

4.8 Bend radius in storage

The principal to follow is to store hose in straight lengths, layed flat on supports, with

(19)

Technical guide

Should the hose be stored in reels, it is preferable to avoid stacking them in piles, as this could create a

permanent deformation of the hose.

Hoses should not be suspended on hooks and in general any flexions or tractions should be avoided.

During use a hose can be subjected to many effects which have not been forseeen. Obviously it is

recommended to use the hose in accordance with our indications concerning working pressure,

temperature, bend radius. In case of doubt, please contact our technical department.

5. Use and maintenance

5.1 Generalities

Hoses should be handled with precaution, they should not be dragged over sharp or abrasive surfaces, tied

in knots, trampled or flattened by vehicles.

5.2 Handling

It is preferable to consult our techical department for any use other than for which it has been designed.

Even so, a chemical compatibility chart according to the different types of elastomers comprising the hose

inner tubes of our range can be found at the end of this catalogue.

5.3 Products conveyed

Should the relative movement of the hose give way to a torsion, the end-fittings and/or connections should

be modified in such a way as to give flexion rather than torsion.

5.4 Torsion

It is advised to consult our technical department for any traction effects to which the hose may be subject,

as we are in a position to carry out traction tests.

5.5 Resistance to traction

Once per year, hoses should undergo visual inspection after cleaning with soapy water or

tensioactive-product based detergents. The hose must be rejected should any of the following defects be

revealed :

- Traces of leaks

- Ripped or torn outer cover

- Slipping of end-fitting

- Abrasion or slash revealing the reinforcement structure

5.6 Maintenance

Should the use be intermittent, that is used alternatively with steam and water following periods of cooling

for example, the innner tube is subjected to thermal shocks

5.7 Specific cases

(20)

Technical guide

leading to the phenomena of “pop-corning”, characterised by localised swelling. In effect, the steam

conveyed through the tube passes through the tube wall (it is for this reason that our hoses have their outer

covers micro-perforated to eliminate the build-up of gasses and avoid swellings). When the steam

circulation is interrupted or during the cooling phase, the steam condenses through the inner tube wall.

When the temperature increases, this water then vaporises again with an increase in pressure. The

alternating effects of these thermal shocks creating localised swellings, deteriorate the inner tube. In all

cases, the hose should be maintained in such a position as to prevent water from stagnating during halts.

It is obviously necessary to consult the chemical compatibility chart at the end of this catalogue, taking into

account temperature and concentration. In case of doubt, contact the technical department. It is

preferable to avoid stagnation of the product in the hose, particularly with regards to solutions or

emulsions as decantation can lead to concentrations above the admissible limits.

5.7.4 Hoses for corrosive or aggressive products

This particularly concerns liquid hydrocarbons, liquids or gases. Road transport rules impose a monitoring

sheet, which must be furnished by the manufacturer, with annual inspections and replacement after 6

years.

5.7.5 Hoses for inflammable products

Users must apply necessary rules concerning cleaning operations (usually with steam) and their frequency.

5.7.2 Hoses intended for food products

Abrasive products remove only a small part of the inner tube material in straight sections. Consequently,

abrasive product handling hoses should be maintained as straight as possible. In situations where bends

cannot be avoided, theses should have a radius as large as possible. Small radii give way to localised wear.

It is the same for sections reduced by an external force, where the abrasive product is accelerated.

It is also necessary to ensure good electrical conductivity in order to evacuate static electrical charges

produced by the rubbing of particles against the inner tube, otherwise leading to a perforation of the tube

wall.

Ref 114 hose is used on fire department hose reels for delivery of water at 40 bars. This hose has been approved by the French interior ministry for use by civil protection services. This hose conforms to nf en 1947 class 1 standards (its inner tube and outer cover are in rubber) category 2 and type C (wp 40 bars and minimum burst pressure 120 bars) : it is therefore a high quality hose. Compared with the red pvc hose which is usually found on booster lines, this hose has many advantages : same flexibility during high summer temperatures or during the winter colds, same working pressure at 20°C or 90°C, better fire-resistance, bend radius and resistance to deformation. it has less “reel-shape memory”, which facilitates use in stairways during interventions on fires in garbage chutes.
