Spiral Wound Gasket Advantages:
1.Have good compression and resilience;
2.With appropriate plasticity, can be tightened to adapt to the sealing surface of the rugged and fill the sealing surface gap to ensure that the system temperature and pressure in the case of alternating with good sealing performance.
3.Has excellent corrosion resistance; in some extreme media is not destroyed, does not produce a large expansion and contraction.
4.High temperature conditions do not soften, no creep; low temperature conditions do not harden, do not shrink.
5.Have sufficient strength, under external load conditions, not crushed; under high pressure, not blown out.
