-1.0 Flow Direction

Band markings and arrows shall be made at the unit battery limits and then on convenient location at the point of use. It is recommended to adopt one method for the entire plant.

1.1.2 For Dia > 4”, dimensions of ‘A’ and ‘D’ shall be 2 x Dia. (18” maximum) and dimensions of ‘B’ and ‘C’ shall be Dia / 2 (9” maximum).

1.1.3 For Dia < 4” , A = 100 mm, B = 50 mm, C = 25 mm and D = 100 mm.

1.1.4 Colour Band ‘C’ is located on down stream side of Basic Identification colour bands and indicates direction of flow. In case of double direction flow, the band ‘C’ will be located each side of band ‘A’.

1.2 Flow direction by Arrows

1.2.1 The arrows shall be situated in the proximity of the basic identification colour and painted White or Black in order to contrast clearly with the basic identification colour.

1.2.2 Arrow size :

- For pipes diameter 2” to 6”, arrow to fit in a 25 mm x 100 mm rectangular.

- For pipes diameter 8” and above, arrow to fit in a 50 mm x 150 mm rectangular.

1.2.3 Where flow of fluid is possible in either direction, the arrows will be indicated one above the other and the arrow heads in opposite directions. The colour of both the arrows will be same.

2.0 Identification with two colour bands (Primary and Secondary)

2.1. The procedure as indicated in Figure – 2 shall be used to identify services (such as for fuel gas, hydrocarbons etc) with two colour bands (Primary and Secondary) as described in Table – 1.

4.0 Details of Contents Code Indication

4.1 The contents code indications shall be painted either in White or in Black in order to contrast clearly with the colour of paint on the pipe or equipment. For insulated lines the code indications shall be painted over the cladding of the insulation.

4.2 The name of fluid flowing inside a pipeline shall be indicated. The line number shall also be painted on the pipelines. The pressure or temperature of the fluid inside the pipeline shall not be indicated.

4.3 The contents code indication as described above shall be painted at following locations or such other places where quick identification is deemed necessary.

Pipe lines : At all junctions, both sides of valves, both sides of service appliances and at intervals of 30 Mtr on straight pipe lengths

For long straight lengths of pipelines, e.g., transfer lines, the interval of 30Mtr for code indication may be varied at the discretion of the Reliance.

4.4 The size of lettering for code indication on the insulated as well as uninsulated pipes is as follows. These sizes are only indicative and may be varied by the Reliance Engineer.

For Pipes : Diameter 2” NB - 25 mm letters For Pipes : Diameter 3” to 6” NB - 50 mm letters

For Pipes : Diameter 8”NB and above - 80 mm letters

5.0 Code Indication for Small Diameter Pipes

Code indication marking by paint may not be done for uninsulated pipelines of nominal diameter 1 ½” and below and for insulated lines less than 1” diameter.

For such pipes, the indication markings shall be punched on lead tags secured to the pipe. Such tags shall be provided at locations described in section 4.3 above. The size of the tag and the method of tying it with pipeline shall be as per advice of the Reliance Engineer.
