small diameter size pipe caps stainless steel butt welding pipe fittings ASME B16.9 end caps

Pipe cap (end cap) is a pipe fitting welded to the end of a steel pipe to cover the pipe. It is used to close the pipeline and has the same function as the pipe plug and plug. Butt welded pipe caps have many shapes, mainly including convex shape, conical shell, variable diameter section, flat cover and tightening mouth.
Convex tube caps include: hemispherical tube caps, oval tube caps, dish tube caps and spherical crown tube caps.

standard system
There are two main systems of international pipe flange standards, namely the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by the US ANSI pipe flange. In addition, there are Japanese JIS pipe flanges, but they are generally only used for public works in petrochemical plants, and have little influence internationally. The pipe flanges of various countries are introduced below:
1. European system pipe flanges represented by Germany and the former Soviet Union
2. American system pipe flange standard, represented by ANSI B16.5 and ANSI B 16.47
3. British and French pipe flange standards, two countries have two casing flange standards.
In summary, the internationally accepted pipe flange standards can be summarized as two different, non-interchangeable pipe flange systems: a European pipe flange system represented by Germany; the other is represented by the United States American pipe flange system.
IOS7005-1 is a standard promulgated by the International Organization for Standardization in 1992. The standard is actually a pipe flange standard formed by combining two sets of pipe flanges from the United States and Germany.
