ASME Section 1 and A358 Cl.1 304H Pipe

ASME Section 1 and A358 Cl.1 304H Pipe

ASME Section 1 and A358 Cl.1 304H Pipe

(OP)
Does anyone know of a code case, where SA358 Cl.1 304H pipe was used in a project that required ASME Section 1 certification?  I bought pipe that is SA358 Cl.1 but I needed it capable of being used in a section 1 application, and I am against a deadline now.  It is my undestanding that Section One of the ASME Code does not allow A/SA358 Cl.1 pipe at all.

RE: ASME Section 1 and A358 Cl.1 304H Pipe

The "S" in SA358 means that it has been approved by ASME for some applications. A358 is the ASTM designation. You need to be careful with "H" as it designates high temp application (which in my opinion is a stretch- an opinion which has gotten my butt kicked by an ASME officer).

RE: ASME Section 1 and A358 Cl.1 304H Pipe

Keep in mind ASME Code Cases are not accepted in all Jurisdictions across the US.

RE: ASME Section 1 and A358 Cl.1 304H Pipe

You might be able to consider this as a SA-240 304H rolled and welded shell with x-ray.  Take a look at the SA358 specification, I think this is basically plate that is rolled and welded from both sides with filler wire.  There are also addtional NDE requirements but I think you would be able to use it based on the understanding that plate was used to form this pipe.

Just my 2 cents.

I'll see if the AI will go for it.  Thanks for the suggestion..

RE: ASME Section 1 and A358 Cl.1 304H Pipe

Hello sjl228,
As you can see :
1) in ASME section 1, PG-5 to PG-10, SA-358 specification is absent;
2) in ASME Section 2  Part A Table ED-1, SA-358 is not allowed for ASME 1 .
3)In ASME section 2 Part D Table 1A, SA-358 is not allowed for ASME 1 .
4)In ASME section 2 Part D Table 1A, SA-358 is not allowed for ASME 8 Division 1.
Sincerely,

RE: ASME Section 1 and A358 Cl.1 304H Pipe

sjl228,
ATsampalas already have answered to your question.
Regarding Code Case, I think, it was use of austenitic material for boiler external piping falling under ASME Section I administrative jurisdiction but assigned to ASME B31-1 technical responsibility.
In plain language you can't use this material to make boiler's proper, but you can use it to built piping for drain, vent, instruments etc till first valve.

Regards,

Curtis
