About Gaskets & Sheet Seals
Gaskets are static seals clamped between two flanged faces to fill surface irregularities and prevent leakage of fluids or gases across a bolted joint. Sheet seals are the cut-from-sheet variety, where gaskets are die-cut or water-jet cut from gasket sheet to suit a flange or cover. The family spans soft non-metallic gaskets (compressed non-asbestos fibre, PTFE, expanded PTFE, graphite, rubber, and rubber-bonded cork), semi-metallic gaskets (spiral-wound, metal-jacketed, and corrugated-metal), and solid metallic gaskets (ring-type joints). Dimensions and materials for pipe-flange gaskets follow ASME B16.20 for metallic gaskets (spiral-wound, ring-joint, and jacketed) and ASME B16.21 for non-metallic flat gaskets, matched to ASME B16.5/B16.47 flange classes. Spiral-wound gaskets combine a metal winding (304/316L stainless, alloy) with a filler (flexible graphite or PTFE) plus inner and outer guide rings, and are colour-coded by winding and filler. Selection considers flange rating and finish, gasket factor m and seating stress y, temperature, and media compatibility, with sheet seals chosen by sheet grade and thickness. Ring-joint gaskets (oval or octagonal) seat in machined grooves for high-pressure service, and jacketed gaskets suit heat exchangers and large vessels. Sheet seals are commonly cut to a customer flange or cover drawing, which makes them flexible for non-standard equipment. Through Himalay, partner manufacturers can typically supply material certificates to EN 10204 3.1 where specified, dimensional inspection, and RoHS/REACH declarations; fire-safe, oxygen-service-cleaned, and low-emission gasket documentation is available for relevant duty, with PED conformity for pressure-equipment joints and material traceability coordinated as part of the standard order flow.
