3D 5D Carbon Steel Seamless Bend ASME B16.28 A53 U-Shaped Bend

Bend is mainly used in the pipe duct of oil and gas meteorites. The purpose is not much different from that of the elbow. In order to have a certain bending angle for the pipe, its product advantage is that it can smooth the transition of the pipe shu road and the angle is very large. Above 120 degrees, the specifications are expressed by wall thickness and diameter. The engineering diameter is a number close to the outer diameter, neither the outer diameter nor the inner diameter. The engineering diameter is used for the standardization of large bend production and is not used for specification expression.
Bend uses a complete set of bending dies to bend, divided into two processes: cold simmering and hot pushing. No matter what kind of machinery and equipment and pipelines, most of them use bend, mainly for oil, gas, liquid, etc.
