Additional Product Information

The part that connects the pipe to the pipe. Connected to the tube end. There are holes in the flange and bolts can be worn so that the two flanges are tightly connected. The flanges are sealed with a gasket. Flanged pipe fittings are pipe fittings with flanges (flange or socket). It can be cast or it can be threaded or welded. A flange joint consists of a pair of flanges, a washer, and bolts and nuts. The gasket is placed between the sealing surfaces of the two flanges. After the nut is tightened, the specific pressure on the gasket surface is deformed after the specific pressure reaches a certain value, and the unevenness on the sealing surface is filled so that the connection is tightly sealed. Some fittings and fixtures have their own flanges and are also flanged. Flange connection is an important connection method for pipeline construction.
The flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are used extensively. In the home, the diameter of the pipe is small, and it is low pressure, and the flange connection cannot be seen. If in a boiler room or production site, there are flanged pipes and equipment everywhere.
In layman's terms, the function of the flange is to fix and seal the pipe joints.
