The name "flat welding" in the name of flat welding flange represents the welding form of the flange, which is different from butt welding flange because the shape and size of the flange are different due to different welding forms, and the usage and pressure resistance are also different.The sealing surface form of plate type flat welded steel pipe flange PL is divided into two types: raised face (RF) and full face (FF).The sealing surface forms of SO with neck flat welded steel pipe flanges are divided into raised face (RF), raised and raised face (FM, M), tenon and groove face (T,

The flat flange has sufficient strength and must not deform during the tightening process. The sealing surface of the flange should be smooth and clean. When installing stainless steel flanges, oil stains and rust spots should be carefully cleaned. Gaskets shall have good oil resistance and aging resistance, as well as relatively good elasticity and mechanical strength.

The main use of flange is to connect pumps, pipes, valves, and other equipment to make a pipework system. Usually, flanges are threaded or welded, and you can connect two flanges by bolting them with gaskets and providing a seal that gives easy access to the piping system.1. Standard:JIS B2220 2.

Flange connection is a removable joint that first fixes two pipes, fittings, or tools to a flange, then provides a flange gasket between the two flanges, and sooner or later makes use of bolts to tighten the two flanges to tightly join them. The connection between stationary pipelines and rotating or reciprocating gear can be achieved.1.

As for iron plate welding flanges, many customers are questioning whether the quality of iron plate welding flanges is better than forged welding flanges. In fact, the quality of iron plate welding flanges is the same as that of forged welding flanges. However, where is the material of iron plate welding flanges that cannot be guaranteed? This means that the material of iron plate welding flanges is the least guaranteed, because in general, the density of iron plate welding flanges is not an issue.
