spiral wound gasket with inner ring

spiral wound gasket 1) graphite gasket + metallic ring inside 2) outstanding resistance and compressibility.

 ® Properties  

     • Spiral Wound Gasket is the best in the compression resilient in all the half-metal seal gasket, which is made by the metal hoop band and different kinds of packing material.

 ® Advantages:

     • We can make its structure density according to the demand of different locking force, and we use the inner and outer circle to control the maximum compact degree. So it can be well suit the rough flange face, especially suit the situation of unbalance load, loose of joint force, temperature and pressure change periodically, concussion and shock.

  ® Usage:

      •  It is widely used in the fields like petrochemical industry, machine, electric power, metallurgy, ship-building, medicine, atomic energy, space navigation.
