Products Description
Basic concept of blind flange:
A blind flange is a flange used to close openings in pipes or equipment, usually where temporary or permanent closure is required. They are widely used in chemical, petroleum, natural gas, and other industries.
Sealing performance of blind flange
The sealing performance of the blind flange is very critical. In order to ensure a good sealing effect, a gasket is usually installed between the two flange surfaces and fixed with bolts. Flange blind plates with different pressure levels require the use of gaskets of different thicknesses and bolts of different specifications.
