XS thickened pipe with a pressure wall thickness of less than DN200 mm is designated as SCH 80.
Three categories of pipe wall thickness are identified by the inner diameter of carbon steel reducers, as specified by MSS and ANSI in the United States:
1. STD stands for standard weight pipe; it is a carbon steel reducer with an inner diameter of less than DN 250 mm. Sch40 is a pipe for STDs.
2. The thicker pipe is symbolized by XS, a reducer made of carbon steel with an inner diameter of less than 200 mm. Sch80 pipe is XS.
3. XXS, or extra thick pipes, are carbon steel reducers having an inner diameter of less than DN 250 mm. An XS pipe is Sch120.
Domestic carbon steel reducers meet all American pipe standards, including XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; and Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS. The two varieties are XS and STD.
The two distinct and non-interchangeable pipe flange systems—the European pipe flange system, represented by Germany, and the American pipe flange system, represented by the United States—can be used to summarize the widely recognized pipe flange standards. framework.
