How about the difference between forged flanges and steel flanges?
Forging flange is a forging process to make flange blank, and then machined flange; steel plate flange is machined after cutting steel flange. Because of the forging process of forged flange, the inner structure of flange is compact and can be used in medium and high pressure condition. The steel plate flange is only suitable for low voltage working condition
High neck flanges are usually forged and used mainly in medium and high pressure.
Hello! The plate flanges and forged flanges are almost indistinguishable from finished flanges and may differ in gloss. Forged flange, he is processed by high temperature grinding tool steel lathe, used in high-pressure flange, usually welding flange series. But the steel flange is a flange to the hot rolling mill out of plate cutting made, mainly suitable for small caliber welding plate flange. You do not doubt the quality of the steel flange, flange plate is not low cost quality suspected, steel plate is a large steel factory after years of experience, and the flange forging in the forging process of extrusion prone interlayer and cracks are not observed, so that the flange plate can buy, and high pressure flange welded flange etc. are forged into doubt, there are steel plate flange there is a lot of small projects, small units he will automatically choose cheap products, the customers accounted for more than 7. Italy Cheng Cheng piping equipment for you to answer, there are technical problems at any time to communicate.
