Description

Technical Field

[0001] The utility model relates to the technical field of flanges, in particular to an anti-corrosion flange. Background Art

[0002] Flange is also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange. Flange connection is widely used in the construction industry, urban water supply, boiler pressure vessels, petroleum industry, gas supply, chemical industry, food industry, fire protection, pharmaceutical industry, power station, water conservancy, HVAC and other industries due to its advantages of good connection sealing, stable structure, high strength, easy use and low cost.
