Spiral wound gaskets are mechanical sealing devices widely employed in high-pressure and high-temperature applications to prevent leakage between mating surfaces. They are made of a V-shaped metal strip coiled in a circular pattern with a soft filler material, such as graphite or PTFE, sandwiched between the metal winding layers. The metal strip offers structural support and toughness, while the filler material ensures flexibility and sealability. This design enables spiral wound gaskets to seal connections exposed to harsh circumstances, making them popular in oil and gas, chemical processing, and power production.

Basic Spiral Wound Gasket: A V-shaped metal strip is coiled in a circular pattern. A soft filler substance, such as graphite or PTFE, is inserted between the metal winding layers. The metal strip adds structural integrity and toughness. The filler substance promotes flexibility and sealability. Suitable for a wide range of high-pressure, high-temperature applications. Commonly utilized in the oil and gas, chemical processing, and power generating sectors. Inner Ring Spiral Wound Gasket: Similar to the classic spiral-wrapped gasket, but with an inner metal ring. The inner ring adds structural support, preventing filler material from leaking into the flange grooves. Enhances the gasket's stability and sealing performance. This is particularly helpful for situations with uneven or damaged flange surfaces. It provides superior resilience to pressure and temperature changes compared to standard spiral-wrapped gaskets. Widely used in critical sealing applications requiring high dependability, such as pipelines, valves, and pressure vessels.
