Spiral wound gasket Is formed by the V-shaped or W-shaped stainless steel belt and non-metallic filler through lamination, spiral winding, and spot welding of the tops and ends. With good compression elasticity, it is applicable to the sealing parts under the intense alternating temperature and pressure, as the static sealing elements at the flange joints of pipelines, valves, pumps, heat exchangers, towers, manholes, handholes, etc.
Product Description:
Spiral wound gaskets are designed for ASME B16.20 and ANSI B16.5 flanges. Spiral wound gaskets are available for classes 150 to 2500. Custom filler, winding strip, guide ring and inner ring materials are available upon request.
