RE: a105 instead of a694

Probably going to depend on your Code of Construction (if any) and perhaps contractural requirements (if any).

code of construction in the compressor station is asme b 31.8

RE: a105 instead of a694

No, but A 106 can be used. A 105 is a specification for forged piping components and not piping itself;

Scope: This specification covers forged carbon steel piping
components for ambient- and higher-temperature service
in pressure systems. Included are flanges, fittings, valves,
and similar parts ordered either to dimensions specified by
the purchaser or to dimensional standards such as the MSS,

RE: a105 instead of a694

ehsankeyvan,

Just to clarify, are you asking about the material for the pipe itself, or the forged fittings?

A105 & A694 are both forging material. A105 is CS forgings, A694 is carbon and alloy steel forgings.
A106 is for seamless CS pipe.

Either way, you'll have to check the code to see what is allowed. Is this question just out of curiosity or is there a reason you're trying to replace A694 with A105?

RE: a105 instead of a694

Yes you can use A-1 in pipeline construction per B31.8. Whether it is acceptable for use on production pipe (like API 5LX-XX) is another story - may be, may be not.

RE: a105 instead of a694

I believe that you are talking about flanges, low carbon steel, both standards, A105 and A694, are very different in the chemical and mechanical requirements,
