Pipe specs/standards for buried pipes application
Pipe specs/standards for buried pipes application
(OP)
Hello everyone,
I am working on a project to construct a pipeline that runs for 5 miles between two terminal to transport Natural Gasoline. The whole pipeline will be buried underground with certain bored sections (ie HDD bores under the river).
Can someone please advise what type of pipes is recommended and what standards and specs to go by for such project?
Thanks in advance

RE: Pipe specs/standards for buried pipes application
In the USA, use CFR 49, Part 195 for liquid pipelines, essentially the same as B31.4 for most situations, but when in doubt, or not, CFR is the law there.
you must get smarter than the software you're using.

I was told that there are different coding for buried vs bored pipes. can someone please explain the difference.
Thanks
RE: Pipe specs/standards for buried pipes application
There is no "separate coding" for HDD pipes AFAIK, as this is simply an extension of pipeline design. There are some established custom and practice, but no difference as far as the design codes I know.
I will have to say though that maybe English isn't your first language, but the wording and questions implies no prior knowledge of this work? You should really be seeking advice from closer to home.
"Butane and Methane" implies gas in which case the design code might be different to what BI states.
Are you asking for the pipeline design code or the pipe design spec? API 5L is the specification normally used for pipelines. Strength of material is a key factor and PSL2 pipe is the usual grade.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

Gas wells typically produce only raw natural gas, while condensate wells produce raw natural gas along with other low molecular weight hydrocarbons. Those that are liquid at ambient conditions (i.e., pentanes-octanes and heavier) are called natural gas condensate, sometimes also called natural gasoline or simply condensate.

B31.4
Butane and Methane, probably B31.8
