ASTM A234 WP22 CL1 / CL3 Alloy Steel Fitting Buttweld 180° Elbow Black Painted

ASME B16.9 Buttweld ASTM A234 WP22 CL1 / CL3 180 Degree Elbow Alloy Steel Pipe Fittings​

WP22 is the designation used to describe the grade of buttweld fittings, it corresponds to the material grade and is part of the ASTM A234 specification for alloy steel fittings. These fittings are available in a range of sizes, and their specifications will generally reference standard dimensions like ANSI/ASME B16.9 for butt-weld fittings. They are classified into different classes based on their minimum yield strength and design applications. The classifications typically refer to the manufacturing process or the intended service conditions of the fittings. Usually, fittings belonging to class 1 and 3 are first liquid quenching followed by the performance of a tempering process. ​
