Flange metal gasket strength and hardness test

　　In the atmospheric corrosion resistance, if is the industrial atmosphere or heavy pollution area, you will need to clean in time to avoid the corrosion. Flange suitable for use in food processing, storage and transportation. High pressure equipment and pipeline, using 10 copper, aluminum, steel, stainless steel type lens or other shaped metal gasket. Flange in the use of specific areas show important performance and value, fully grasping the use of specific operations and contribution, ordinary is suitable for the occasion of temperature below 120 ℃, Pressure is lower than 5 mpa, for general corrosive medium, the most commonly used is acid-proof asbestos board. High pressure washer and sealing surface contact width is very narrow (line contact), processing with gasket sealing surface roughness is higher.

　　Polyurethane whether or heat-resistant steel, stainless steel plate shape the best comprehensive properties of steel, austenite have enough strength, and has excellent plasticity and hardness is not high also, this is also one of the reasons they are widely used. Pneumatic actuator is a kind of can produce plastic deformation, and has certain strength rings made of materials. Valve pressure testing machine most gaskets from non-metallic plate cutting, or produced by professional factory in accordance with the provisions, the size, the material of asbestos rubber sheet, asbestos board, PE board, etc.; Another with steelskin belt with asbestos tape winding of spiral wound gasket. Different stress of flange bolts with different thickness and use different.

　　We have adopted advanced production equipment and technologies to manufacture our blind flanges and A105 weld neck flange, which can not only improve product quality, but also save raw materials. Our products have high strength, good toughness and resistance to corrosion.
