The difference between groove flange and high diameter flang
Brief introduction: Grooved flanges are flanged flanges with grooved grooves. High neck flange: the neck height is high, the stiffness and carrying capacity of the flange are improved. Compared with butt welding flange, welding workload big, electrode consumption is high, can't withstand high temperature and high pressure and repeated bending and temperature fluctuations, but the installation is convenient, can omit the weld inspection process production, more popular.
The difference between: 1, groove flanges are used in fire and water piping. High neck flanges are commonly used for high temperature, high pressure, inflammable and explosive, highly toxic, and the clean cleaning requirements in the pipeline.
The grooved flanges have been seen on imported equipment. It's two docking and it's the same structure of the flanges, and there's a very deep groove on the surface, and when you combine the two flanges, and you add an iron ring in the middle to make the seal, Flange height to diameter is in the crater on the surface of the flange of the combined with raised portion, a ring for the welds with pipe connection, the flange has national unified standard, but used more in the south of China, the north is rare,
