advantages of butt welding flange

1. It is easy to align butt-welded flange during welding and assembling, and the installation is simple and convenient.
2. It can be widely used in metallurgy, machinery, chemical industry, fuel, machine tools, water conservancy engineering, construction, engineering, ships, environmental protection, coal, agricultural machinery, food, boiler pressure vessels and other industries.
3. Butt-welded flanges are mostly used in mild medium conditions, such as low-pressure non-purified compressed air and low-pressure circulating water. Their advantages lie in the relatively low price. The strict sealing face of butt welded flange can be divided into three types: smooth, concave-convex and mortise-groove.
Smooth butt-welded flange has a wide range of applications, and the other two types of butt-welded flange are also more in use. The butt welded flange has reasonable structure, high strength and stiffness, can withstand high temperature and high pressure, repeated bending and temperature fluctuation and other very bad environment, and will not reduce the sealing performance.
