Product Description

Vortex gasket JIS gasket
Vortex gasket is made of intercalarted V or W type formed steel belt and nometalic belt which are helically winded. The rainforced rings can be added according to the operating duty request. So it has the strong points of multichannel sealing ,high temperature endurance, corrosion-resistantance and lower requirement of the coarseness of the flange sealing surface.
 
It is widly used in power plant, aviation,petrochemical,and valve industry,etc.It is applied in the medium of steem, hydrogen, natural gas, pyrolysis gas, and petrol products, acid, alkali,and salt solution,etc.
