We are is a professional A234 WP5 Pipe fittings,Elbow,Tee,Reducer, Pipe end Caps, chrome moly pipe fittings manufacturer in China.As a experienced A234 WP5 Pipe fittings manufacturer in China We can produce high quality steel pipe fittings,
ASTM A234 WP5 Pipe Cap is a type of alloy steel butt weld fitting used to close the ends of piping systems.
It is manufactured from Chrome-Moly alloy steel (5Cr-0.5Mo) and designed for use in high-temperature and high-pressure services, such as power plants, refineries, and petrochemical industries.
The material complies with ASTM A234 / ASME SA234 for wrought alloy steel fittings and is often used with ASTM A335 P5 seamless pipes.

Manufacturing process of ASTM A234 WP5 steel pipe fittings:
The process of A234 WP5 pipe fittings manufacturing is called “wrought” which means it is casted or forged.Usually the ASTM A234 WP5 elbows,tees,reducers are made from A335 Gr P5 Seamless steel pipes,the A234 WP5 caps are made from plates.
