Geberit HDPE jointing methods

Overview

The many Geberit

jointing methods

offer solutions

for all situations.

Butt weld Electroweld sleeve

coupling

Ring-seal socket Screw-threaded joint

Linear expansion socket

Flange joint Contraction sleeve Coupling for PE-Silent

and adaptor only

These connections have different properties, and are therefore classified according to the way in which they are assembled as follows:

a) To be opened

Jointing methods which can be disconnected after assembly.

b) Not to be opened

Jointing methods which cannot be disconnected after assembly.

c) Tension-resistant

Connections which withstand tensional forces.

d) Non-tension-resistant

Connections which cannot withstand tensional forces.

b) not to be opened c) tension-resistant

Use

Welding is the easiest jointing method, providing the many advantageous bene-fits of prefabrication; HDPE needs no other component in order to be welded. It can be used in all circumstances where prefabrication is used on site or in the workshop.

The essential conditions for a perfect weld are:

• Cleanliness of the welding plate and the parts which are to be welded. • A correct welding plate temperature.

• The correct pressure for jointing the parts. • The parts to be welded must be cut square <) 90°.

Butt welding takes up little space. The edge of the weld does not obstruct the pipe, leaving its internal cross-section virtually unchanged. Even quite complica-ted distribution parts can be assembled in a small space, without wastage of material, because lengths of pipe or elbow sections can be easily reused through butt welding.

The allowance for butt welds is approx. as big as the wall thickness of the pipe.

Electroweld sleeve coupling

A short, simple and reliable connection Available from ∅ 40 to 315 mm. Connection properties b) not to be opened c) tension-resistant Use

On-site welding, conversion, additional installations, repairs. The small outside diameter

provides a great advantage.

Conventional assembly, on the nesting principle, made for easy use. The joint obtained is simple, quick and reliable.

The heating and melting zone is divided into two fields, as there are no electrical resistances in the centre of the sleeve. This provides a very satisfactory safety factor.

Also the ends of the pipes are not heated, the zones remain effectively cold, and provide

further reinforcement, thus cancelling out shrinkage of the pipe.

The pressure required for welding is obtained from the shrinking effect of the sleeve when it is heated, and is evenly distributed over the entire weld. This shrinkage has a compensating effect on pipe diameter measurement toleran-ces.

The electrical resistance wires will not corrode. Once the weld has been made they are

entirely covered by PE.

The use of original Geberit equipement, especially tempered Geberit HDPE pipes, are

recommended for correct welding.

Electrical sleeves can be made to slide by removing the central stop ring, thus making system conversion and repair work easier.

B.500.000/191

The stop ring can easily be removed with a screwdriver.

Assembly instructions are the same for both ring-seal sockets and screw-threaded joints, the sleeve lengths are the same for corresponding diameters. The effective sleeve length, i. e. the measurement – X – from the O-ring to the base of the socket governs the maximum length of pipe which can be connected by individual joints.

For HDPE approximately 15 mm of spigot should be allowed for every 1 m of pipe.

The pipe must be fully inserted into the socket, because the socket does not act as an expander. Owing to the pipe thickness and the low thermal conductivity of HDPE, the socket seal has very satisfactory resistance to heat and no shrinkage of the O-ring occurs.

The O-ring has a round seat regardless of pipe movements. The O-ring remains fixed in the seat and is always in contact with the pipe.

Use

Ring-seal socket joints can be used to provide a connection between various prefabri-cated parts for simpler assembly.

Assembly

May be used either vertically or horizontally. The small overall dimensions provide an advantage where space is limited. Can easily be assembled or released even where access is difficult.

Ring-seal sockets are provided with a yellow protection cap to prevent the ingress of debris during installation.

Screw-threaded joint

Available from ∅ 32 to 110 mm. Connection properties a) to be opened d) non-tension-resistant Use

Use

Wherever there is the possibility that a pipe can be pulled out of a screw-threa-ded joint by axial tensile forces a flange bushing must be used to ensure that the connection will resist these forces. It is also recommended that a screw-threaded joint with flange bushing should be used when installing in floors or slabs, where the length of pipe between two connections (elbows, branches or sleeves) is longer than 2 metres.

Expansion socket

Available from ∅ 32 to 315 mm. Connection properties b) not to be opened d) non-tension-resistant Use

An expansion socket is recommended between anchor brackets, particularly on installations assembled with rigid joints and where excessive thermal movement is anticipated.

At least one expansion joint must be provided on vertical stacks running from floor to floor, long collector pipelines and before connecting to the buried drain pipework.

Different conditions apply for underground installations. For this application field see page 48.

Installation

Can be used either vertically or horizontally. One advantage is the depth of the sleeve which makes the assembly of downpipes and mains easier, allowing both vertical and horizontal corrections (e.g. in level, and in the precise positio-ning of the direction of branches and elbows).

A firm anchor bracket must always be located behind the expansion socket to avoid any movement of the socket in the event of expansion or contraction.

The special shape of the seal allows the pipe to slide within the socket during expansion and contraction, ensuring that the connection remains perfectly watertight even under heavy hydraulic load.

Horizontal assembly (e.g. at 20°C)

Example: Insertion depth in an ambient temperature of 20°C

(Vertical assembly).

The following conditions are important to ensure perfect and easy assembly of the sleeve:

1. Chamfering the inserted pipe end to approximate <) 15°.

2. Check the scale on the outer surface of the expansion socket for insertion depth.

The Geberit HDPE contraction sleeve is a convenient connection possibility for most uneven, irregular or special materials.

A common additional application method is also the connection from HDPE to different clay ware apparatus, e. g. for Laboratory sinks.

Installation

The enclosed rubber ring will be placed over the pipe end. Make sure that the rubber ring will be placed in the middle of the sleeve length (h2). Then push the contraction sleeve over the pipe end. Apply low heat (approx. 125°C) evenly around the socket, moving the blow lamp constantly.

The sleeve will now shrink and give an absolute watertight and strong connection. Afterwards fix the contraction sleeve pipe with an anchor bracket.

For Ø 125–315 mm use two soft flames.

The main purpose of the anchor bracket is to prevent any movement of the expansion socket.

The distance «L» and the thrust forces «P» have to be taken in account, when selecting the diameter of the pipe nipple between mounting plate and bracket.

The thrust force «P» is the slide resistance between rubber seal and HDPE pipe. This force depends on the pipe diameter.

Embedded fixed points

Principal: Any variation in length must be prevented by embedded fixed points in concrete (e. g. electroweld sleeve couplings, branches, bends or collar bushes) or by the provision of corresponding fixed point structures.

B

Embedding in concrete

Basically Geberit HDPE material absorbs within itself thermal movement due to its high elasticity.

However, in the case of large diameters (e.g. 315 mm) the forces «P» (resulting from expansion and contraction) are considerable. They must be absorbed by the embedded fixpoints alone, since cement/concrete will not adhere to HDPE pipework.

Since the fitting has to act as a fixpoint, do not insulate it.

Under no circumstances should a ring seal or expansion socket be embedded in concrete. Reduced small branches of large pipe diameters must be secured by an additional anchor point (electroweld sleeve couplings or collar bushes) to prevent shearing off of the branch.

Underground drainage pipes for housing

Underground

drainage pipes of Geberit HDPE

Not only has Geberit HDPE proven itself excellently for many years for drainage systems inside of buildings such as:

– soil and waste stacks – vent pipes

– connection and branch pipes – collector pipes

but it is also suitable for under-ground applications as: – ground pipes

– domestic drainage pipes

Criteria for underground drainage pipes

1. Tightness

2. Resistance to chemicals Geberit HDPE provides the

assu-rance of universal resistance

to the greatly diversified types of chemical attack by the disposal water, as well as by external factors (acidic soils).

3. Flexibility

Geberit HDPE is a flexible, operatio-nally reliable drainage system, even in soils in which a certain degree of settling of ground must be anti-cipated.

4. Resistance to frost

Geberit HDPE has proven itself excellently for many years in frost endangered soils such as in Scandinavia. It can be used in

tem-applications. In addition to the attack from the inside, the pipes are also subjected to attacks from outside. Geberit HDPE excellently stands up to all these requirements.

Guidelines for laying drainage pipes

Trench

The trench is to be dug as narrow as possible – but not narrower than the pipe diameter + 40 cm. The floor of the trench must be level and free from rocks and loose clumps. Correct elevation and slope are also impor-tant.

1

B = Bedding

Under normal soil condi-tions the trench is provi-ded with a bedding layer of round gravel (grading up to 30 mm) or of bro-ken material (grading up to 10 mm) of a thickness of approx. 100 mm. The bedding layer must be compacted and tamped. In certain cases it will be neccessary to reinforce the ground.

2

U = Underpinning

After the pipe has been laid, recesses are to be provided for sockets and flanges so that the pipe is supported along its entire length. The underpinning is to be done with a tamping post or the like. It must be done very carefully. If seve-ral pipes are laid, make sure that the lowest one is fully covered before the one above is placed. The pipe must lay flat, and it must be installed with the correct slope.

3

C = Consolidation layer

The material is to be filled in layers of approx. 100 mm thickness. Tamping can be done by stamping with the feet, or with a special tool. The purpose of this material is to help prevent the pipe from deforming, so that it must be compacted well on both sides at the same time .

4

2

P = Protective layer

Now fill in a layer of the same material (must not contain rocks which could cause point loading of the pipe) of at least 300 cm.

For the further filling the available material is to be used. The trench must not contain rocks which can-not be lifted by hand.

Rigid installation

The rigid fixings must be stronger

than the possible expansion or contraction forces of the HDPE pipe.

Geberit pipes can be installed rigidly with relatively low effort, for which the following elements are required:

(51)

Please note:

The scale found on the outer surface of the socket does not apply in the case of underground installations.

Underground installation of

Geberit expansion sockets

In addition to the butt-welded and electrically welded connection, the expansion socket is an ideal connection in underground draina-ge systems. Since in such systems lower temperature differences are usually encountered than in stacks and connector pipes, smaller length variations can be accounted for.

For this reason in underground installations the distance between expansion sockets can be longer.

The values arev calculated accor-ding to the formula

With regard to the ground line between the building wall and the street sewer, where extreme settling can occur, an installation mat must be wrapped around the ground line to act as a deflection leg.

In such cases Geberit HDPE is an ideal material, since it assures tightness and at the same time provides maximum flexibility.

Drainage requirements for bridges

Traffic safety/Maintenance

Geberit HDPE also meets the special requirements for all types of bridges. The pipes and the wide range of fittings provide an easy design and execution at the cons-truction site. The smooth walled pipes make a trouble-free mainte-nance and service possible, whereby all modern cleaning equip-ment can be used.

Heating tape

Where the bridge crosses a river, railway or another road, an absolu-tely watertight system is essential. In accordance with the anti-pollution laws, protection must be maintained in the event of an accident.

(55)

Drainage of bridges

Installation indications

Laid in concrete

Piping embedded in the bridge structure can never be replaced. It is therefore essential that a drainage material which offers the greatest security is used. When choosing this material, the consolidation of the concrete, temperature varia-tions, contraction and creep, as well as the prestressing of the bridge must be taken into consideration.

Thermal movement

The following points must be obser-ved

– Location of supports or piles – Horizontal movement of

the bridge on the supports – Deflection of the bridge – Swaying of the bridge

– The watertightness of the expan-sion socket (example 1)

In the case of example 2 an expan-sion funnel is required to absorb the lateral movements.

Fixing

The spacing of the guide brackets for HDPE piping is 1,5 m and may not be exceeded. With all plastic piping, the pipe bracket should have a minimum width of 60 mm, in order that the stresses due to the weight of the filled pipe is well distributed.

Low pressure installation

Low pressure application

Discharge pipeline of a pump set

Generally the Geberit HDPE product range is designed for water drainage systems.

For the low pressure range, e. g. swimming pool, pipework through circulation pumps, Geberit has established maximum admissible stressing values for an endurance life of 10 years.

Pressure max. 1,5 bar Temperature max. 30°C Longterm

rupture strength 10 years

All connections must be butt weld joints, electroweld sleeve couplings or flange joints.

Suitable fitting range for low pressure application see page 4.

The Geberit HDPE range of products can also be used for the discharge pipeline of a pump set, provided that the mechanical stress is low, only of short time and no thermal loaded medium (e.g. warm water) is pumped.

When designing discharge pipelines for drainage pumps the following important points should be observed:

1. The discharge pipeline has to be installed higher than the lowest installed appliance by means of a pipe loop.

2. If the flow rate is smaller than 5 l/s the vertical fall section of the pipe loop has to be increased.

3. If the flow rate is above 5 l/s the vertical stack has to be vented with a ventilation pipe of at least 50 mm inside diameter.

4. Long horizontal collector pipes have to be vented. The minimal inner diameter of the vent pipe must be 57 mm or 2 dimensions smaller than the discharge pipe.

The ventilation pipe must be higher than the total delivery head of the pump and must go above the roof.

External pressures

Internal negative pressures

External pressures

Permitted external pressures

Geberit HDPE pipes will withstand external pressures according to the table below depending on the pipe diameter.

The maximum level of the groundwater table has to be taken into account when designing Geberit HDPE pipelines in a groundwater area.

Internal negative pressures

Geberit HDPE pipes will withstand internal negative pressure according to the table above depending on the pipe diameter.

Geberit HDPE pipes are sometimes used as suction pipelines for pumpsets. The higher the suction lift is, the higher the negative pressure inside the pipeline. Important with such an installation is that the foot valve and strainer are not blocked.

Foot valve and strainer of the suction pipeline should be kept free from debris, possible blockage could lead to additional pressure increase.

Fire protection

Depending on the type of building different fire protection will be required (see local fire regulations for buildings).

Building parts

The requirments for building com-ponents are classified in fire resi-stant

classes in order to maintain maximum integrity of the relevant wall, floor or ceiling.

The weakening of a fire protection wall or ceiling is not allowed under any circumstances.

The integrity of the wall or ceiling will be maintained for the permitted periods when Geberit fire stoppers are used as illustrated.

Once the temperature in the room which is ablaze reaches a certain level, the intumescent material expands as a foam and closes off the cross-section of the pipe, therefore preventning (for a certain required length of time) the fire and smoke from spreading through the opening.

Ecological properties of Geberit HDPE

Polyethylene (PE) is a simple compound of carbon and hydrogen atoms, harmless to man, animals and plants.

PE is the perfect material for drainage systems from an ecological point of view. It has a long life span, no toxic gases rises from incineration (e. g. hydrochloric acid HCL from PVC) during disposal. It consumes much smaller quantities of energy during fabrication process and transport than steel, cast iron or cop-per pipes.

PE environmental loads relate to the fields of manufacture and disposal. In addition to the raw material crude oil, energy is used for the preparation of the plastic granulate and in the manufacture of the products.
