What is the difference between SCH40 and SCH40S?
What is the difference between SCH40 and SCH40S?
(OP)
I wonder if the only difference would be just thick.?
It happens that the thickness of the spool at one point and according to the BOM of the plane tells me SCH40 and elsewhere indicates that I should be SCH40S, would I use the tube in place at SCH40 SCH40.
Best regards

RE: What is the difference between SCH40 and SCH40S?
In general, I believe the -S designator arises from the .19 standard which used to be for stainless pipe. At (i.e. above) certain sizes, Sch40 and Sch40S are not the same anymore. Hence the need to spec if youre using B36.10 or B36.19.
RE: What is the difference between SCH40 and SCH40S?
The S usually signifies stainless Standard sizes, especially 10S which is not normally made in carbon steel.

Is that a bad assumption?
