Clearance Between Underground Pipeline B31.8 1

SmallInfo · Jan 14, 2022

Hi experts,
Is there any clearance specified in B31.8 (Gas Transmission and Distribution Piping Systems)for two buried pipelines? I can find the clearance between buried pipeline and underground structure (image attached) but unable to find clearance between two buried pipelines.
Thanks in advance

Another pipeline can be regarded as a structure in this instance.

Most of the time you are limited by the other pipeline owner and his legal rights.

300mm is the smallest usually and 500mm very common.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I have 2003 Edition. The clearance requirements for plastic piping,

and Para. 841.143 is for steel piping and excerpt at your post.

So , incase of pipeline , min. clearance 150 mm and for gas main 50 mm.

You may look to the definitions of gas pipeline and ( distribution)gas main.
