It has been known that the national standard flange, the flange material and workmanship are in line with national standards. The national standard flange (English standard flange) refers to the flange piece produced according to the provisions of the People's Republic of China's national standard "GB/T 9112~9124-2010 Steel Pipe Flange". Our GB 2 piece flange ball valve can be forged and cast. The cast flange has a precise shape and size, a small amount of processing, and a low cost, but it has casting defects (swells, cracks, inclusions); the internal streamline of the casting is poor (if it is a cutting part, the streamlined shape is worse. Forged flanges generally have lower carbon content than cast flanges and are less likely to rust. Forgings have a good streamline shape, a denser structure, and better mechanical properties than casting flanges. Improper forging processes can also result in large or uneven grain sizes, hardening cracking, and forging. Higher than cast flanges. In industrial pipelines, flange connections are used extensively. In the home, the diameter of the pipe is small and it is low pressure and the flange connection is invisible. If in a boiler room or production site, there are flanged pipes and equipment everywhere.
