What Are ASTM A234 WP11 Pipe Fittings?
ASTM A234 WP11 Pipe Fittings are made according to the ASTM A234 standard for the butt weld pipe fittings. The standard is international and there are different grades of materials in this standard that are being used to produce the pipe fittings. The WP11 is one of these standards which includes seamless pipes for high pressure and temperature applications. C&N Hongcheng is a manufacturer and supplier of the ASTM A234 WP11 fittings in different sizes, types and grades. There are different manufacturing methods such as forging, hot rolling and cold drawing and heat treatments. The products also vary in type such as bends, elbows, reducers and connectors.

How Many Types of Steel Pipe Elbow?
According to the shape, there are straight and reducing elbow.
Depending on the angle, there are normally 45 degree, 90 degree and 180 degree elbow.
As based on radius, there are long radius ( 1.5D) and short radius ( 1D) elbow.
For connection, they can divided into socket weld elbow, butt weld elbow and threaded elbow.
