Carbon Steel FF RF Wn/So Forged Flange

SO refers to the type of flange, the full name is Slip- on flange. The full name of Slip-on flage is neck flat welded steel pipe flange. It is a flange that extends steel pipe and pipe fittings into the flange and connects with equipment or pipe through fillet weld. Advantages: SO flange with neck also belongs to flat welded flange, because there is a short neck, thus improving the strength of the flange and improving the bearing strength of the flange. So it can be used in higher pressure pipelines. SO flange flange is mainly used for gas valves and natural gas pipelines. Because the short neck can improve the stiffness and bearing capacity of the flange. Plate welded flanges are used for general media. SO flange flange is suitable for inflammable, explosive, corrosive, toxic places. The sealing surface of SO flange flange can be convex surface, concave and convex surface and tenon surface. They differ in construction, sealing effect and strength. SO flange are generally…
