Notes on flange connection

flange connection is an important connection method for pipeline construction

flange connection is to fix the two pipes, pipe fitting injection boxes and the measuring technology or equipment adopting the newly developed mixing head on a flange respectively, add flange pads between the two flanges, and fasten them together with bolts to complete the connection. And some pipe fittings and equipment that can be recycled have their own flanges, which also belong to "flange connection", explained Liang Bin

flanges are divided into threaded (threaded) flanges and welded flanges. Low pressure small diameter threaded flange, high pressure and low pressure large diameter are welded flanges, and the thickness of flange plates and the diameter and number of connecting bolts under different pressures are different

according to different pressure levels, flange gaskets also have different materials, from low-pressure asbestos gasket, high-pressure asbestos gasket to metal gasket

flange connection is convenient to use and can withstand large pressure. Flange connection is widely used in industrial pipelines. In the family, the pipe diameter is small, and it is low-pressure, so the flange connection cannot be seen. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere

also known as flange or flange. Parts that connect pipes to each other. Connected to the pipe end. There are holes on the flange, which can be threaded with bolts to make the two flanges tightly connected. The flanges are sealed with gaskets. Flanged pipe fittings refer to pipe fittings with flanges (lugs or adapters). It can be cast (not shown in the figure), or it can be formed by threaded connection or welding. Flange, joint is composed of a pair of flanges, a gasket and several bolts and nuts. The gasket is placed between the two flange sealing faces. After tightening the nut, the specific pressure on the gasket surface reaches a certain value and deforms, and the uneven part on the sealing face is filled, so that the two force arms of the connection and compression are tight.
