IS 15190 : Part 1 : 2002 Acetylene Pipelines - Code of Practice - Part 1 : for Pressures Up to 155 kPa (g)

1 Scope

1.1 This code covers the design, fabrication, erection, testingand commissioning of acetylene gas pipelines having a maximumworking pressure (P_W) of 155 kPa (g) (1.5kg/cm² g) operating at a temperature up to 60{bmc°C. The pipeline covered herein is intended to conveycommercially available gaseous acetylene containing small amountsof impurities normally present when produced from calcium carbideas per IS 1040 and used for welding, brazing, cutting and alliedprocess.

1.2 Conveying pipe size covered under this Code is up to andincluding a nominal diameter DN 100 mm. However, it is generallyrecommended to restrict the pipe size to DN 50. Pipes of size up toDN 100 may be used only wherever special requirement calls fortheir use.

1.3 This code does not cover the following:

a) Pipelines conveying mixtures of acetylene gas with dilutents,

b) Pipelines for interconnecting acetylene compressor withdownstream equipment such as dryers and acetylene gas cylinderfilling manifolds,

c) Cylinder discharge manifolds, and

d) Acetylene pipelines in a chemical plant where the gas is usedas a process feed material.

Section 3 Fabrication and welding

Section 4 Erection and testing

Section 5 Purging and commissioning
