Carbon Steel Buttweld Fittings Welding elbow
Description
Welding elbow, its production process is, if do long radius elbow, must first select specifications, put forward pipe material. Through theoretical calculation, the expanding rate is generally between 33% and 35%, which can be pushed back. After selecting the raw materials, cut according to the elbow specifications, and then consider the curvature radius, for example, 90 ° elbow, through its curvature can calculate the length of cutting, and 90 ° elbow can be processed. It can be calculated by theoretical calculation, and then cut with the length as the ruler. Finally, the material is made by hot pressing.

Characteristic
Welding elbow adopts hot push forming. You may have seen the pusher, but it's actually very simple. It is a horn shaped core or mandrel. The mandrel changes from thin to thick. The pushing process is a process of expanding and bending. There is a support at the back to put the blanking pipe section into the mandrel, and a archway frame at the back to fix the mandrel. There is a car in the middle. Some cars are driven by hydraulic transmission, some by mechanical transmission, that is, lead screw transmission, and then push the car forward. The car pushes the pipe along the mandrel. There is an induction ring outside the mandrel to heat the pipe. Then the car pushes the pipe down and processes it.
