Industrial Spiral Wound Gaskets (ASME B16.20)

Designed to deliver exceptional resilience and tight dynamic sealing under extreme thermal and mechanical fluctuations, our industrial spiral wound gaskets ASME B16.20 provide robust flange containment across high-pressure pipelines, heat exchangers, steam systems, and chemical processing plants. Constructed by winding alternating metal strips with compressible filler materials, these semi-metallic seals effectively absorb flange movement, thermal expansion, and line vibration without losing structural integrity or seal stress.

We manufacture and stock a complete range of standard and custom metallic spiral wound flange gaskets—including Style V (Winding Only), Style CR (Outer Centering Ring), Style RIR (Inner Ring Only), and Style CGI (Inner & Outer Rings) for raised face and flat face flanges. Built with premium winding metals (304SS, 316L, Duplex, Inconel, Monel) and high-performance fillers (Flexible Graphite, PTFE, Thermiculite), our spiral wound sealing solutions satisfy stringent emissions standards, offering fire-safe, blowout-resistant performance for critical industrial and oilfield applications worldwide.
