A234 B16.9 Carbon Steel Pipe Bend
ASTM WPB A234 B16.9 SEAMLESS AND WELDING CARBON STEEL PIPE BEND
Bend is a kind of pipe fitting, it is adopted the complete bending device to curve, divided into two kinds, cold heat and hot push technology. Most machine equipment and pipeline all use bend, mainly used in oil, gas, infusion, engineering bridge construction, etc.
According to the radius of curvature points: can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature is equal to 1.5 times the outer diameter of tube, R = 1.5 D. Short radius elbow refers to its radius of curvature is equal to the pipe diameter, R = 1.0 D. To bend diameter (D, R for the radius of curvature).
