ASTM A234 Grade WPB Butt-Weld Elbows
The Butt-Weld Elbow is a wrought pipe fitting that facilitates a crucial change in the direction of a fluid flow, typically at 90° or 45°. It is joined to the pipe by butt welding, creating a permanent, highly secure, and leak-proof system. The standard for this fitting material is ASTM A234 Grade WPB, which specifies Wrought Carbon Steel for pressure piping and high-temperature service. This fitting grade is perfectly matched for piping systems that incorporate ASTM A105 flanges, which are secured by ASTM A193 Grade B7 Stud Bolts and their complementary A194 Grade 2H Heavy Hex Nuts. The material's strength and weldability ensure that the piping system maintains its integrity under the severe mechanical and thermal stresses typical of critical high-pressure lines in power plants and refineries. Zeron Fasteners offers these elbows in both Long Radius (LR) and Short Radius (SR) to meet specific hydraulic and space requirements.
