        Flanges can be divided by size: small flange, medium flange, large flange, by connection type can be divided into: plate flat welding flange, energetic flat welding flange, welded flange, socket welding flange, threaded flanges, etc., where it focuses on the process of making large flange and purpose.

 

       Large rolled flange flange is a kind commonly used in machinery industry and promotion, users get the praise and favor. Roll flanges widely, depending on the use of determined characteristics, conditions are used for medium to ease the situation, such as non-purified air pressure, low pressure circulating water, which has the advantage of relatively cheap. Rolled flanges for nominal pressure of not more than 2.5MPa pipe connections, rolled flange sealing surface can be made smooth style, lenticular and tenon slot three. Smooth style rolled flange largest application, two other ways of rolled flanges in use is relatively common. Rolled flange includes a variety of types and models, welded steel flanges for flange and pipe welding counterparts, mainly used in welding technology, the use of good performance characteristics and performance, reasonable structure, strength and stiffness , and can withstand high temperature and pressure, and repeated bending and temperature fluctuations, reliable seal, nominal pressure of 0.25 ~ 2.5MPa of rolled flange sealing surface irregularities. Rolled flange main application environment is appropriate, the need to determine the specific situation to ensure that the specific use of rolled flanges value and performance, and withstand high temperature and pressure.

Large roll flange plate cut into planks, and then rolled into round. Reprocessed waterline, bolt holes, etc.. This is generally large flange, the maximum can be done 7 meters. Such flanges have a good quality assurance. Because raw materials are in the plate, good density. Materials are carbon steel, stainless steel, alloy steel.

 

In the machinery industry, many manufacturers use the flange (can also be said stiffening ring) just as the connection or the supporting role so that you can use to strip (flat) directly in the volume directly on the device flange into the required volume the ring can be, this processing method provincial labor and materials, significant cost savings.
