Gas Piping Coods

Firstly - CONFIRM with your jurisdiction/regulator & your client.

Depending on the exact use, pressure (which you indicated incorrectly - I can only assume you mean kg/cm²), location and purpose, it could be any of the following, including others I have neglected to mention-

• ASME B31.8 (pipelines and distance transmission) *I suspect this is what you want*
• BS EN 13480
• ASME B31.3 (piping within industrial plant/setting)
• NFPA 54
• ICC International Fuel Gas Code

I think that you have to go API 1104. ADOLFO
