About this part

Precision-wound spiral gaskets designed for sealing high-pressure, high-temperature steam lines, boiler stop valves, and heat exchangers. Composed of alternate V-shaped metallic stainless steel winding strips and flexible expanded graphite filler, reinforced with a solid carbon steel outer centering ring and inner ring to prevent radial blowout under intense thermal expansion cycles.

Key features

  • Alternating V-shaped SS304/SS316 metal strip and high-purity flexible graphite filler
  • Solid outer centering ring for accurate bolt circle alignment and blowout prevention
  • Inner compression ring to prevent turbulent erosion and internal filler extrusion
  • Excellent recovery and spring-back resilience under thermal cycling and pressure surges
  • Rated for pressures up to Class 1500# and temperatures up to 550°C

Typical applications and wear

Main steam distribution manifolds, boiler stop valve flanges, PRV stations, and superheater pipelines. Wear stems from improper bolt torque, thermal over-cycling, and flange face pitting.

Compliance

Conforms strictly to ASME B16.20 and DIN EN 1514-2 high-pressure sealing standards.
