ASTM A234 WP9 pipe fittings are butt welding pipe fittings,includes elbows,tees,reducers and caps.They are commonly used to be welded with the ASTM A335 P9 steel pipes and A182 F9 forged pipe fittings and forged flanges.
ASTM A234 WP9 is low content alloy steel material,it have a good performance in high temperature conditions. Grade WP9 have two classes,Class1 and Class3.They have different mechanical properties.It is necessary to choose the correct class when install the piping systems.WP9 Class 3 have a better yield strength and tensile strength.
The butt welding joint of ASTM A234 WP9 pipe fitting makes it have a good strength in the piping system,it is leakproof and strong.
The ASTM A234 WP9 pipe fittings could be used in industry field,like Oil,Gas,Power plant,Water Treatment,Chemical-industry etc.
