70/75 Shore a Black NBR Rubber Gasket and Sealing Material Gasket for Pipe and Flanges Spiral Wound Gaskets

Spiral wound gasket comprise a mix of metallic and filler material. Generally, the gasket has a metal (normally stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.Spiral wound gaskets are designed for ASME ,DIN,JIS flanges.There are usually 4 types of spiral wound gasket ,R/IR/CG/CGI.

Product Feature

For accurate positioning, the  Spiral Wound Gasket is provided with a metal inner reinforcing ring and an outer positioning ring. The inner and outer steel rings are used to control its maximum compression degree, and the surface accuracy of the flange sealing surface contacted by the gasket is not high. There are various kinds of color options, thus to provide more choices to meet need.

 

Product Description

This Spiral Wound Gasket is equipped with advanced process, which has longer service life for use and there is no special need of maintaining. In addition, it is made of thin steel strips alternately wound with various fillers. It can withstand high temperatures and high pressure, with high performance. By changing the material combination of the gasket, our Spiral Wound Gasket can solve the problem of chemical corrosion of the gasket by various media. Its structural density can be made according to different locking force requirements.
