Weld Neck Flange related introduction
Welding Neck Flange is one of the flange, widely used in machinery industry and the promotion, users get the praise and favor. Welding Neck Flange of the wide range of USES, use according to the characteristics of different, more than in the mild conditions of medium, such as suit low circulating water, the purification of compressed air, and it has the advantage of the price is cheaper.
Welding Neck Flange forging can be divided into free forging, upsetting and extrusion, die forging, closed die forging, closed upset. Closed die forging and closed upset because there is no flash, material utilization ratio is high. With a process or a few process can complete complex forging finishing. Since there is no flash, forging stress area is reduced, the required load is also reduced. However, we should pay attention to not make blank completely is restricted, so we will strictly control the volume, control the relative position of forging die and measure of forgings, effort to reduce the wear and tear of forging die. Flat welding flange in cold forging, the size of the forgings changed little. Welding Neck Flange is suitable for the nominal pressure of not more than 2.5 MPa steel pipe connection, Welding Neck Flange sealing surface can be made into smooth type, concave and convex type and mortise type 3 kinds. Smooth type Welding Neck Flanges are the biggest, the other two ways of Welding Neck Flange in use is also common.
We have adopted advanced production equipment and technologies to manufacture our blind flanges and threaded flanges, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
