Stainless steel strip for spiral wound gaskets
Metal seals for flanges, pipework and plants.
Gaskets and spiral-wound gaskets
In spiral-wound gaskets a profiled stainless steel strip is wound in a spiral together with a filler material, producing a seal that withstands high pressures and temperatures. Stainless strip is also used for reinforcing rings and flat metal gaskets.
In spiral wound gaskets the strip is formed into a V profile and wound together with the filler: consistent width and thickness are essential for the windings to nest evenly and for the gasket to reach its design thickness. 3S supplies narrow stainless steel strip from 3 mm wide in grades such as AISI 304, 316L, 316Ti and 321, with EN or ASTM tolerances and 100% dimensional control. The annealed 2R/BA condition eases profiling. Traverse-wound spools provide long continuous lengths, reducing joints and winder stoppages. A 3.1 certificate is available on request for plant documentation.
