What is the connection method of vacuum flange?

Vacuum Flange connection is an important connection method in pipeline construction.
Flange connection is the process of fixing two pipes, fittings, or equipment onto a flange plate, adding flange pads between the two flanges, and fastening them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections.
Flanges are divided into threaded connection (threaded connection) flanges and welded flanges. Low pressure small diameter threaded flanges are used, while high pressure and low pressure large diameter flanges are welded. The thickness of flange plates and the diameter and quantity of connecting bolts vary for different pressures.
According to different levels of pressure, flange gaskets are made of different materials, ranging from low-pressure asbestos gaskets, high-pressure asbestos gaskets to metal gaskets.
The flange connection is easy to use and can withstand high pressure.
In industrial pipelines, flange connections are widely used. In the home, the diameter of the pipeline is small and it is low-pressure, so flange connections cannot be seen. If there are flanged pipes and equipment everywhere in a boiler room or production site. Flange connection is the process of fixing two pipes, fittings, or equipment onto a flange plate, adding flange pads between the two flanges, and fastening them together with bolts to complete the connection. Some pipe fittings and equipment already come with flanges, which also belong to flange connections.
Pay attention to ensuring that all bolts are tightened uniformly when connecting, especially when tightening bolts.
