The wall thickness of Screwed Pipe Fittings wall thickness

　　The Screwed Pipe Fittings wall thickness grade is indicated by the Screwed Pipe Fittings number, the ANSI 304 Stainless Steel Screwed Pipe Fittings number is Sch40 and Sch80. When selecting the welded pipe fittings, the pipe should be the same as the pipe number of Screwed Pipe Fittings to which it is connected, that is, the strength of pipe and pipe, Thick), except that the wall thickness of the end of Screwed Pipe Fittings is the same as the wall thickness of Screwed Pipe Fittings . China's National Standard for Steel Butt Welded Pipe Fittings (GB12459) and China Petroleum & Chemical Corporation Standard (SH3408) are basically the same as ASME B16.9, B16.28, JIS, JPI-7S and JPI-7S-1.
