thread o lets

(OP)
i am looking at a piping drawing and it is asking for Thread o let 6000LB,SCF,CS,A105.
DOES ANY ONE KNOW WHAT IS SCF?

RE: thread o lets

I reviewed ASME B16.11, and since this was on a drawing instead of markings on an actual fitting, I would tend to believe SCF is being called out for Special Class Fitting.

RE: thread o lets

Here is a descriptor for SCF from Kitz concerning SS fittings. Could someone have just changed the material?

There are special cleanliness requirements for CS pipe and fittings for certain processes, like Phosgene gas.
