JT-G1000CGI Spiral wound gasket with inner and outer ring

At present, the most widely used sealing gasket is the gasket with the best resilience among the semi-metallic sealing gaskets, which is formed by alternately winding V-shaped or W-shaped thin steel strips and various fillers. The chemical corrosion of gaskets by various media can be solved by changing the material combination of gaskets. In order to strengthen the main body and accurate positioning, the metal inner reinforcing ring and outer positioning ring are adopted, and the inner and outer rings are used. Control the maximum compression degree to strengthen and avoid loose rings of the basic body. Due to the existence of the outer ring, the gasket is more convenient to install. It is generally used in flat and convex flanges of medium and low pressure. It can withstand high temperature, high pressure and adapt to ultra-low temperature or vacuum conditions. It does not require high surface accuracy of the flange sealing surface contacted by the gasket, and it is convenient for disassembly and assembly in petroleum, chemical industry and metallurgy Sealing of flange joints such as pipes, valves, pressure vessels, condensers, heat exchangers, towers, manholes and handholes in industries such as gold, electric power, shipbuilding and machinery, performance characteristics of spiral wound gasket with inner and outer rings equipment for winding pad.

The following are general parameters:
