There are many types of large diameter flange forging process, and the flange price difference is not small.
Large diameter flange forging process is as follows:
1. This process is mainly used for large diameter flanges with the required interface in the center. Although soldered, the basic finished weld is not shown above and is not recommended for use in high pressure piping.
2. Steel plate - cutting is usually carried out using steel plates made by regular enterprises, and the materials are regular. Mainly used for small diameter machining. Tread is relatively flat, cheap, good quality and relatively easy to work with.
3. Scrap iron pin - Smelting - Embryo Production This is a low-cost forging method, most of which is processed in small workshops, so it is difficult to guarantee the material.
4. The forging flange is dense, the material is good, and the quality is higher, but the processing is troublesome.
