Use of large-diameter flanges
The common large diameter flanges are flat welding flanges and butt welding flanges. There is no large diameter threaded flange. In actual production and sales, flat welding products still account for much. The structure and scope of use of flat-welded large-diameter flanges and butt-welded large-diameter flanges are different, and the characteristics and advantages that can be displayed will also be different. Therefore, they must be used in different scopes to ensure that the flange plays an important role. . Large diameter flat welding flanges have poor rigidity and are suitable for occasions with pressure p≤4MPa; butt welding flanges, also known as high neck flanges, have greater rigidity and are suitable for occasions with higher pressure and temperature. There are three types of flange sealing surface: flat sealing surface, suitable for occasions with low pressure and non-toxic media; concave-convex sealing surface, suitable for occasions with slightly higher pressure; tongue and groove sealing surface, suitable for flammable and explosive , Toxic media and high pressure occasions. Flange pipe fittings of different properties have good product performance in different fields, and the effects of different applications and spaces will be different.
A manufacturer of large-caliber welding flanges. The welding flange is a part that connects the pipe to the pipe and is connected to the pipe end. The welding flange has holes and bolts to make the two flanges tightly connected. The gasket is sealed between the two flanges. The welding flange is A disk-shaped part, the most common in pipeline engineering. Welding flange (flange) connection is to fix two pipes, pipe fittings or equipment, respectively, on a weld. Between the two welds, a flange gasket is added. Fasten together with bolts to complete the connection. Welding is an important connection method for high-pressure pipeline construction. Welded flange connections are easy to use and can withstand greater pressure.
