What Is Metal Flange Part Shape?

A flange is a disk-shaped part of a mechanical structure with flange edges that can be bolted together, such as an edge, rim, rib, or ring protruding from a wheel or large diameter pipe, used to increase the strength of an object, to hold an object in place, or to attach one object to another. Flanges are used in pairs.
All in the two plane around the use of bolt connection at the same time closed connection parts, generally known as "flange", such as the connection of ventilation pipe, boiler room steam transmission pipe connection; Flange connection is an important connection mode in pipeline construction.
Flange connection is the two pipes, pipe fittings or equipment, respectively fixed on a flange plate, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection.
Flange is divided into threaded connection (wire connection) flange and welded flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connecting bolt diameter and number are different.
Flange connection is easy to use and can withstand greater pressure. Flange pads come in different materials according to different levels of pressure, from low pressure asbestos pads, high pressure asbestos pads to metal pads.
