Manufacturing process and application of large flange

Large flange is one of the flanges,which is widely used and popularized in the machinery industry,and has been well received and favored by users. Rolled flanges have a wide range of uses, and the scope of use is determined according to different characteristics. They are mostly used when the media conditions are relatively mild, such as low-pressure non-purified compressed air and low-pressure circulating water. Its advantage is that the price is relatively cheap.

The rolled flange is suitable for the connection of steel pipes with a nominal pressure not exceeding 2.5MPa.The sealing surface of the rolled flange can be made into three types: smooth, concave and convex, and tongue and groove. The rolled flange includes many types and models. Butt welding flange is used for butt welding of flange and pipe. It is mainly used in welding technology. It has good performance characteristics and performance. Its structure is reasonable, its strength and rigidity are large, and it can withstand high temperature and pressure and repeated bending and temperature fluctuations. The sealing performance is reliable. The rolled flange with a 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 to withstand high temperature and high pressure.

Large flanges are cut into slats with a middle plate and then rolled into a circle. The water line and bolt holes are processed.This is generally a large flange,which can be up to 7 meters.This type of flange has a good quality guarantee.Because the raw material is the middle plate, the density is good. The materials are carbon steel, stainless steel, alloy steel,etc.

In the machinery industry,the flanges (also called reinforcement rings) used by many manufacturers are only used for connection or support, etc.,so that they can be directly rolled into the required flange rolling equipment with steel tape (flat steel) The ring can be used.This processing method saves labor and materials, and greatly saves costs.
