Spiral Wound Gasket in Refineries: Why It’s the Industry Standard for Critical Sealing
In refinery operations, equipment runs under extreme temperatures, high pressure, and aggressive chemical exposure. Sealing failure can lead to production losses, safety hazards, and costly shutdowns. This is why the spiral wound gasket has become the preferred sealing solution in refineries worldwide. Let’s explore why spiral wound gaskets dominate refinery applications and what makes them uniquely reliable. What Is a Spiral Wound Gasket? A spiral wound gasket is a semi-metallic gasket made by winding a metal strip and a soft filler material together in a spiral pattern. The metal strip provides strength and resilience, while the filler material ensures sealing and adaptability to flange imperfections. Common materials include: Stainless steel windings Graphite filler PTFE filler Inner and outer guide rings This layered design gives the gasket flexibility along with structural stability. Why Refineries Prefer Spiral Wound Gaskets 1. Excellent Recovery and ...
