Product introduction

This product is widely used in the static sealing of flange joints of machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and various instrument industries, such as pipes, valves, pumps, heat exchangers, towers, manholes, handholes, etc. Main materials: metal belt and inner ring are made of stainless steel, and filler materials are asbestos, flexible graphite, polytetrafluoroethylene, non asbestos fiber, ceramic fiber, etc.

Product features

● The spiral wound gasket has good compressibility and resilience, multiple seals and certain self tightening functions.

● It is not too sensitive to the surface defects of the flange compression surface, and does not bond the flange sealing surface.

● It can partially eliminate the influence of pressure, temperature change and mechanical vibration.

● It can maintain its excellent sealing performance under various harsh conditions such as high temperature, low temperature, high vacuum, impact vibration and other cyclic changes.
