Spiral wound gaskets for ASME b16.47 A series flanges

Spiral Wound Gasket

Stainless Steel Spiral Wound Gasket 

There are four type of the gasket: the basic type(HSA), the inner ring gasket( HSB), the outer ring gasket(HSC), and the gasket with inner and outer ring(HSD).
Pre-press forming metal corrugated belt and non-metal belt alternately overlap,spiral wound made. Also according to the conditions required to add reinforced ring.Spiral wound gaskets for ASME b16.47 A series flanges

Main Features

1) Due to the role of the inner ring, played a role in blocking the media to erode the sealing surface，and the outer ring has played a role in strengthening the positioning, is a high-performance sealing products.
2) Have good compression and resilience;
3) 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.
4) Has excellent corrosion resistance; in some extreme media is not destroyed, does not produce a large expansion and contraction.
5) High temperature conditions do not soften, no creep; low temperature conditions do not harden, do not shrink.
6)There is the role of inner and outer rings, so that in the course of use, under high pressure, not blown out.In the extreme medium is not easy to be corroded, life expectancy increased and extended.Economic security, convenient and quick.It is the best choice for high temperature, high pressure.
