Product Description

ASME B16.9 Carbon Steel 45/90/180 Degree Seamless Butt Welded Fitting Elbow Bend

Descriptions of Elbows

Elbow is a pipe fitting used to change the direction of fluid flow in a piping system. It features high pressure resistance, high temperature resistance, corrosion resistance, excellent sealing performance, and long service life.

 

Optional materials include cast iron, malleable cast iron, stainless steel, alloy steel, and carbon steel. Connection methods include direct welding, flange connection, hot-melt connection, electrofusion connection, threaded connection, socket connection, and clamp connection.

Based on manufacturing processes, elbows are classified into welded elbows, stamped elbows, push-formed elbows, and cast elbows. This fitting is widely used in chemical, construction, petroleum, power, natural gas transmission, municipal engineering, and shipbuilding industries, serving as a directional change and connection point for different pipe diameters in piping systems; it is also known as a butt-welded elbow, among other industrial names.
