Pipe series standard
The American pipe series (ANSI B36.10 and ANSIB36.19) is a typical "large outer diameter series" with a nominal size range of DN6 to DN2000mm. There are two ways to indicate its wall thickness.
One is to use the pipe number "SCH" to indicate the wall thickness.
①The ANSI B36.10 standard includes ten grades: SCH10, SCH20, SCH30, SCH40, SCH60, SCH80, SCH100, SCH120, SCH140, and SCH160.
②The ANSI B36.19 standard includes four grades: SCH5s, SCH10s, SCH40s, and SCH80s.
The second method is to use the weight of the pipe to indicate the wall thickness of the pipe. It divides the wall thickness of the pipe into three types:
Standard weight pipe, indicated by STD;
Thickened pipe, indicated by XS;
Extra thick pipe, indicated by XXS.

Why are elbows made of stainless steel?
Stainless steel stamped elbows are suitable for pipeline systems in petroleum, chemical, hydropower, natural gas, construction, and steam storage tank industries because they can be used directly as raw materials without the need for blanks. Large-diameter thin-walled carbon steel elbows can serve as low-cost pipe-making equipment and molds. By shortening the production cycle, production management costs can be significantly reduced. Especially for large steel elbows, the blank surface is smooth, with good ductility, and the stamping process is simple, precise, easy to operate, and assembly and welding processes are also very convenient.
