SCH160S

[clay87]

To what size specification is Schedule 160 Stainless Steel (316) pipe made? B36.19 (Stainless Steel Pipe) doesn't include Sch 160 but does state:

ASME B36.10M [wrought steel piping] includes other pipe thicknesses that are also
commercially available with stainless steel material.

 

[XL83NL]

Our main SS supplier has Sch 160 available for all standard grades of stainless teel, duplex, and some ferritc grades, like 304, 309, 316, 321, 347, duplex grades 32205, 403, 405, 409, and standard product forms like ASTM A312, A358, A790. Most SS suppliers will do so.

The best things to do might just be to contact your SS supplier and ask him for his programme.


PS:
- where in B36.19M is your quote found? I couldnt find it in the 2004 edt.
- its Sch 160 or 160S (choose, but) note the latter is the designation per B36.19M [Stainless Steel Pipe] and Sch 160 is the designation per B36.10M. E.g. Sch 40S therefore is a double designation (if Im correct).

It's in the scope.

its Sch 160 or 160S

I think Sch is just an abbreviation for "Schedule" and the S suffix invokes B36.19M. Lack of a suffix invokes B36.10M??

For schedule 160 pipe made of 316SS, I think the proper designation is Sch 160 and not Sch 160S since B36.19M doesn't include the stronger schedules.

And "S" on the end of a schedule designator number indicates that it is an "alloy" pipe which means that it isn't carbon steel. It can be stainless, but isn't necessarily limited to stainless.

If you read through some of the ASME B31.X piping codes, you can find that clearly defined. I can't remember which one it is specifically but suspect that it might be B31.3.
