Proper installation of large flanges is important. When installing large flanges, two large flanges should insist that the sealing surface of parallel and large flanges should not be damaged and should be cleaned.

When the medium is corrosive, the local flange contact medium (flanged short segment) for high grade data such as stainless steel, and the external low data such as carbon steel data of the flange ring clamped it to complete the sealing; The advantages of flat welding flange in the welding assembly of flat welding flanges are easy to match, and the price is relatively cheap, so it is widely used.

Application scope of butt welding flange: the butt welding flange is not easy to deformation, good sealing, widely used, suitable for pressure or temperature greatly wavering pipeline or high temperature, high pressure and low temperature pipeline, the advantage is cheap compared with the price, nominal pressure less than 2.5MPa; It is also used in the pipeline with expensive, flammable and explosive medium. The nominal pressure is about PN16MPa.

Welding flanges include many types and models, welding steel flanges for flange and pipe welding, mainly used in welding technology, good performance and performance, its reasonable structure, strength and stiffness. Requirements according to the detailed status of the welding flange of the detailed application value and performance, accept high temperature and high pressure.
