Seal Gasket Background

Gasket seal occupies a very important position in modern industrial enterprises, sealing quality is directly related to the continuity of production, property safety, energy saving and environmental protection and people's physical and mental health, so the development of gasket more and more people's attention. With the rise of modern industry, especially modern petroleum, chemical industry, atomic energy industry, large power stations, pressure vessels to high temperature, high pressure, high vacuum, cryogenic and large-scale, multi-series direction, the gasket seal constantly put forward new requirements, a variety of new materials and new structures continue to appear, its sealing performance is also very different. In addition, the fluctuation of pressure, the change of temperature, the relaxation of the bolt pre-tightening force, the tilt and dislocation of the flange, the defect of the sealing surface, and the corrosion of the medium will have a great impact on the sealing effect. Therefore, how to correctly select the appropriate sealing gasket according to the working condition and how to correctly install it is the key to ensure the sealing effect.
