Large stainless steel flange is a kind of flange, which is widely used and promoted in the machinery industry, and has been well received and favored by users. The rolled flange has a wide range of uses. The range of use is determined according to different characteristics. It is mostly used in situations where the medium conditions are relatively mild, such as low-pressure non-purified compressed air and low-pressure circulating water.
The rolled flange is suitable for steel pipe connection with a nominal pressure not exceeding 2.5 MPa. The sealing surface of the rolled flange can be made into three types: smooth, concave-convex and tongue-and-groove. Smooth rolled flanges have a large amount of applications. The other two types of rolled flanges are also more common in use. Rolled flanges include many types and models. Butt-welded steel flanges are used for butt welding of flanges and pipes. They are mainly used in welding technology and have good performance characteristics and performance.
Its structure is reasonable, its strength and rigidity are large, it can withstand high temperature and pressure, repeated bending and temperature fluctuation, and its sealing is reliable. The rolled flange with nominal pressure of 0.25 ～ 2.5MPa adopts concave-convex sealing surface. The main application environment of the rolled flange is suitable. It needs to be determined according to the specific situation to ensure the specific use value and performance of the rolled flange, and to withstand high temperature and pressure.
