ASTM A234 WP22 CL3 Buttweld 90 Degree LR Alloy Steel Elbow B16.9 For Fired Heater
ASTM A234 WP22 Alloy Steel Elbows are commonly used in piping systems for high-temperature and high-pressure applications， particularly in the oil and gas， chemical processing， petroleum and power generation industries. ASTM A234 WP22 CL1 / CL3 Buttweld Alloy Steel Elbows consist of low-alloy steel with the inclusion of chromium and molybdenum. This combination of elements provide excellent resistance to corrosion， high-temperature and high-pressure environments. ASTM A234 WP22 Alloy Steel Elbows have high tensile strength， good impact resistance， and excellent ductility， which make them suitable for being used in applications where high reliability is required. Our Group supplies alloy steel buttweld fittings for many years， including 45/90/180 degree elbows， equal tees， reducing tees， concentric reducers， eccentric reducers and so on.
