Blind Flange Manufacturers prefer to check beforehand rather than rework afterwa
Blind flange is also called flange cover and blind flanges. It is a flange without holes in the middle for sealing the pipe plug. The function is the same as that of the welded head and the screw cap, except that the blind flange and the screw cap can be removed at any time, while the welded head can not. There are many types of sealing surface, such as plane, convex, concave and convex, tenon and groove, ring connection surface. The production process is mainly divided into forging, casting, cutting and these three kinds. The casting flange has accurate shape and size, small workload and low cost, but it has casting defects (pore, crack, inclusion); the inner structure streamline of the casting is poor (if it is a cutting part, the streamline is worse); and the forged flange is generally lower than the cast flange in carbon content, less rust-prone, better streamline, denser structure and better mechanical properties than the cast flange; Flange cover can contact our shengtian company, we also have various flanges, such as national standard flange and German standard flange and non-standard flange and British standard flange or American standard flange, with high quality
