Stainless Steel (SS) Spiral Wound Gaskets
Our premium Stainless Steel (SS) Spiral Wound Gaskets utilize high-grade metallic winding strips and guide rings, primarily sourced in SS 304, SS 316L, or SS 321, and paired with high-purity flexible graphite or PTFE fillers. This construction ensures maximum resistance to chemical degradation, high temperatures, and structural blowouts. These stainless steel variants are crucial for mitigating flange face erosion and micro-leakage, offering an unyielding seal across aggressive chemical lines, steam networks, and cryogenic processing operations.
Key Features
✓ Exceptional Recovery Under Fluctuating Loads
✓ High Resistance to Blow-out & Pressure Surges
✓ Precise Centering with Solid Metal Outer Rings
✓ Prevents Turbulence with Protective Inner Rings
