Standards for industrial pipe fittings and valves

I’ll send you a standard catalog for reference; although it’s not very comprehensive, I believe it will be sufficient! There should be PDF versions available for download on the forum! Another suggestion for the original poster: if you want to learn the standards, go to the *sharing section! 1.
