The 6" 150# Spiral Wound Gasket with a Carbon Steel (CS) Outer Ring is specifically engineered for demanding industrial applications requiring reliable sealing under high temperature, pressure, and corrosive conditions. This gasket features a robust spiral construction combining a V-shaped metal strip with a flexible filler that provides excellent resilience and ability to accommodate surface irregularities. The carbon steel outer ring offers enhanced rigidity and protection to the soft sealing elements, ensuring durability and preventing gasket blowout, especially in flange connections rated for 150 pounds per square inch. Its design ensures a secure, leak-proof seal in pipelines, pressure vessels, and heat exchangers where standards compliance and long service life are critical. Ideal for use across various chemical, petrochemical, and power generation industries, this gasket supports process integrity, reduces downtime, and optimizes plant safety.

The carbon steel outer ring enhances gasket rigidity and prevents extrusion or blowout during high-pressure sealing in 150# rated flanges, improving durability and sealing reliability.
Yes, the combination of stainless steel winding and filler materials like graphite or PTFE makes it suitable for chemically aggressive environments, with the outer carbon steel ring providing mechanical protection.
Yes, this 6" 150# spiral wound gasket is designed to fit standard ANSI B16.5 flanges commonly used in industrial piping systems.
The gasket can operate effectively between approximately -200°C to 540°C depending on the filler material used, making it versatile for various high-temperature applications.
Typically, the filler material is integral to the spiral winding structure and not replaceable, as it is essential for maintaining the gasket's sealing function and flexibility.
A Spiral Wound Gasket (SWG) is a type of industrial gasket that is widely used in high-temperature, high-pressure, and corrosive environments. It consists of a V-shaped metal strip and a softer filler material that is wound in a spiral fashion to create a resilient sealing surface.
