Ringkasan

254 SMO stub end is a pipe fitting made from 254 SMO, a high-alloy super-austenitic stainless steel (also known as 6Mo super-austenitic). It is designed for use with lap joint flanges in piping systems requiring exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking in severe chloride environments.
