Flat Welding Flange Introduction
Flat welding flange, including plate flat welding flange, with neck flat welding flange.
Flat-plate flange (PL)
Flat welding flange for nominal pressure not exceeding 2.5MPa steel pipe connection.Flat welding flange sealing surface can be made of smooth, bump and tongue-and-groove type three smooth flat welding flange the most widely used. Used for more moderate media conditions, such as low pressure non-purified compressed air, low pressure circulating water.
With neck flat welding flange (SO)
With neck neck welding flange lower neck height, the flange stiffness, carrying capacity has increased. Compared with butt welded flange, welding workload, high welding rod consumption, can not withstand high temperature and pressure and repeated bending and temperature fluctuations, but the site installation is more convenient, you can omit the weld pat rub injury process, more popular.
