Alloy Steel Buttweld Fitting ASTM A234 WP9 180 Degree SR Elbow B16.9
YUHONG GROUP is engaged in manufacturing of a wide range of Butt Weld Fitting that is available in varied types such as L/R & S/R elbow, tee, concentric and eccentric reducers, reducing elbow & tee, cross and caps.
The ASTM A234 is a standard of pipe fitting material and WP9 is the grade. This material standard indicates that the fittings consist of various carbon steel and alloy steel. Different types of pipe fittings are available under this specification like reducer, tees, couplings, caps, etc., and each of them have varied functions. One can get seamless and welded variants of the ASTM A234 WP9 pipe fittings.
