Stainless Steel Pipe

Stainless Steel Pipe

Stainless Steel Pipe

(OP)
For stainless steel pipe schedule 10S, what does the S mean?
I've found references to suffix S in the schedule number is used to differentiate B36.19M pipe from B36.10M pipe.
Any info on these two?

RE: Stainless Steel Pipe

The S means it is the stainless steel schedule, which in some cases is different from (or includes thinner walls than) the carbon steel sizes.

Carbon steel pipe dimensions, for example, are given in ASTM A53.  Stainless dimensions come from some other ASTM standard.

RE: Stainless Steel Pipe

ASME B36.19M - 1985 Stainless Steel Pipe Standard covers the standardization of dimensions of welded and seamless wrought stainless steel pipe. The word pipe is used as distinguished from tube to apply to tubular products of dimensions commonly used for pipeline and piping systems. Pipe dimensions of sizes 12 and smaller have outside diameters numerically larger than the corresponding size. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes. The wall thicknesses for sizes 14 through 22 inclusive of Schedule 10S, for size 12 of Schedule 40S, and for sizes 10 and 12 of Schedule 80S are not the same as those of ANSI/ASME B36.10M. The suffix "S" in the Schedule Number is used to differentiate B36.19M pipe from B36.10M pipe. ANSI/ASME B36.10M includes other pipe thicknesses which are also commercially available with stainless steel material

RE: Stainless Steel Pipe

In looking up some ASTM specifications for SS pipe, I find in each case, they refer back to the ANSI B36.19 standard mentioned above.

BOO1, what is the B36.10 standard?  Is it for tubing rather than pipe?  Or for CS pipe rather than stainless?

RE: Stainless Steel Pipe

ANSI/ASME B36.10M standard is for steel pipe

RE: Stainless Steel Pipe

Superbee,

As JStephen has said, "The S means it is the stainless steel schedule, which in some cases is different from (or includes thinner walls than) the carbon steel sizes."

To underline this, take a look at this page, and pay special attention to the line at the bottom.

The page relates to Carbon and Stainless Steel Welding Neck Flange Bores.

I hope this helps.
