Designed more than 100 years ago, Spiral Wound Gaskets are widely used as high integrity and sustainable gaskets. The sealing element is manufactured from preformed, V-shaped metallic windings with intermediate soft sealing fillers. Most used filler materials are Graphite and PTFE or LeaderTHERM NXT 1000 (high temp. modified Phlogopite). Due to the gasket construction, Spiral Wound Gaskets offer high compressibility and recovery. Leader Style SR Spiral Wound Gaskets are provided with an outer guide ring. The SR gaskets are suitable for ASME B16.5 raised faced flanges up to 600 Class and for EN/DIN flanges up to PN40. Inner ring shall be furnished for all PTFE fillers spiral wound gaskets and FG filled unless the customer specifies otherwise. ASME B 16.20-2008
Petrochemical Industry, Steam, On- and Offshore exploration, pipeline systems, pressure vessels and exchangers.
Spiral Wound Gaskets can be used in a wide variety of media, i.e. a pH range varying from 0-14. Application/ compatibility guide is available on request. Temperature from –450 °F up to 850 °F (steam up to 1200 °F)
