ASTM A234 WP9 CL1 / CL3 Alloy Steel Buttweld Pipe Fitting 180 Degree Elbow

B16.9 ASTM A234 WP9 CL.1 / CL.3 Alloy Steel 180 DEG. Elbow Buttweld Pipe Fittings​

ASTM A234 WP9 pipe fittings have a good performance in high temperature conditions.Grade WP9 have two classes-- Class1 and Class3 with different mechanical properties. It is necessary to choose the correct class when install the piping systems. ASTM A234 WP9 Class 3 have a better yield strength and tensile strength.

Other low carbon alloy grades such as: WP1, WP11 Class 1, WP11 Class 2, WP11 Class 3, WP12 Class 1, WP12 Class 2, WP22 Class 1, WP22 Class 3, WP5, and WP9 shall be furnished in the annealed, isothermal-annealed, or normalized and tempered condition. If normalized and tempered, the tempering temperature for WP11 Class 1, WP11 Class 2, WP11 Class 3, WP12 Class 1, and WP12 Class 2 shall not be less than 1150 °F [620°C]; for Grades WP5, WP9, WP22 Class 1, and WP22 Class 3 the tempering temperature shall not be less than 1250 °F [675°C].
