Types of Other Flange
Special Steel Socket Thread Flange
When welding the flange, the transverse contraction of the weld is easy to cause the deformation of the flange, so the corresponding technological measures must be taken to control the welding quality and deformation of the flange during the welding process.
Special Steel RJ Flange
Although the structure is relatively simple, strict requirements are carried out in the whole manufacturing process, such as reasonable selection of materials, electrode configuration, welding quality control, etc.
Special Steel Non-standard Flange
Check according to the specification, model, diameter and pressure against the corresponding flange standard, and the dimension deviation can refer to the dimension tolerance in the standard.
Carbon Steel RJ Flange
The different characteristics are that users who understand carbon steel flanges may know that carbon steel flanges have fierce scrubbing during the beginning and the sealing process.
Carbon Steel Non-standard Flange
A circular groove is opened in the middle of the two flanges, the metal ring is placed in, the two flanges are hit hard, and the flange is hard connected.
Carbon Steel Socket Thread Flange
Low pressure small diameter threaded flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and quantity are different.
