What should carbon steel flanges pay attention to in daily use?First of all, we don't put carbon steel flanges in damp places, because carbon steel will rust after being in contact with water for a period of time, the surface will change, and the corresponding mechanical properties will also change.
The basic process of carbon steel elbow forming is: first, weld a polygonal ring shell or a polygonal fan-shaped shell with both ends closed. After the internal pressure is filled with pressure medium, the cross-section gradually changes from polygon to circle and finally becomes a circular ring she
Because the Carbon steel butt welded fitting is easy to produce cold crack, hot crack and other defects during welding, it is necessary to take some special process measures to weld normally.1. Welding methodAll kinds of arc welding methods can be used to weld medium carbon steel. Because medium car
Carbon steel elbow in accordance with the production process can be divided into: welding elbow, stamping elbow, casting elbow and so on. Valve testing machine Most gaskets are from non-metallic plate, or by the professional factory in accordance with the size of the production, its materials for as
Heating temperature is a key index in heat treatment of large diameter flange and other flange fittings. The selection and control of heating temperature involves the quality of heat treatment and the final product quality, therefore, how to choose the proper heating mode and how to control the heat
