Threaded flange of stainless steel
The threaded flange is the interconnected part of the shaft and the shaft. It can be used for the connection between the pipe ends. It can also be used for the connection between two devices. The flange is divided into a threaded flange, a welded flange and a clip flange. The low pressure pipe can be used with a wire flange. The welded flange is used for pressures above 4 kg.
The production process of flanges is generally divided into four types. The first one is forged flanges. Relatively speaking, this type of flange is the best quality and the most expensive type of flange; the second is the casting flange, in addition to cut flanges and rolled flanges, in general, rolled flanges are large diameter flanges.

Compared with the forged flange, the cast flange has the advantages of accurate shape and size, small processing volume and low cost, but there are casting defects (pores, cracks, inclusions); the internal flow of the casting is poor;
Forged flanges generally have lower carbon content than cast flanges and are not easy to rust. The internal structure of the forgings is uniform, there are no harmful defects such as pores and inclusions in the castings; the line shape is good, the structure is relatively dense, and the mechanical properties are superior to the casting flanges.
Thread flange nominal diameter: DN8 ~ DN100
Working pressure: 1.0 to 2.5 (MPa)
Threaded flange material: stainless steel, carbon steel, alloy steel.
There are two kinds of threaded flanges. The nominal pressure of a threaded flange is low, and it is generally used in galvanized steel pipe and other occasions where welding is not suitable. The other is used for high pressure conditions, using external threads and machined into a certain shape of the two pipe ends with sealing gasket to seal. This kind of flange used to be used for synthetic ammonia production. In addition, threaded flanges should be avoided on any pipe that may undergo crevice corrosion, severe erosion, or cyclic loading
