The production materials of the flange cover

The flange cover is also known as blind plate flange or blind plate. It is a type of flange without holes in the middle, used to seal pipeline plugs. Its function is the same as that of welded caps and threaded pipe caps, except that the blind plate flange and threaded pipe caps can be removed at any time, while the welded caps cannot.

Flange sealing and leakage sealing treatment methods

Flanged sealing mainly depends on the tight connection between the flange plates and the role of the sealing gasket. The following are some key elements to ensure the sealing of the flange: 1. Selection of flange: Choose the appropriate flange material and specifications according to the pressure, temperature and medium characteristics of the pipeline system. Stainless steel flanges have become the first choice in many fields because of their excellent corrosion resistance and strength.

The key difference between high-quality valve body and low-quality valve body determines the "fate" of industrial equipment!

In petroleum, chemical industry, electricity and other high-demand industrial scenarios, the quality of the valve body, as the core component of the fluid control system, not only determines the operating efficiency of the equipment, but also directly affects the safety, stability and long-term operating costs of the production system. A high-quality valve body means lower risk, longer service life and higher economic benefits.
