It is mostly used under mild medium conditions, such as low-pressure non purified compressed air and low-pressure circulating water. Its advantage is that its price is relatively cheap. Rolled flange is suitable for the connection of steel pipe with nominal pressure no more than 2.5MPa. The sealing surface of rolled flange can be made into lubricating type. The application of lubricating type rolled flange is large, and the other two types of rolled flange are relatively common in application.

The manufacturing process of large diameter flange is to cut the medium plate into lath, and then roll it into circle. Then process water line, bolt hole, etc. In this way, it is usually a large flange, which can be up to 7 meters. The raw material is medium plate with good density. Large diameter flange materials are carbon steel, stainless steel, alloy steel, etc.

There are three types of large diameter flange sealing surface: plane sealing surface, which is suitable for places with low pressure and non-toxic medium; concave convex sealing surface, which is suitable for places with slightly high pressure; mortise sealing surface, which is suitable for places with flammable, explosive, toxic medium and high pressure.
