The Spiral Wound Gasket 0.5" 150# with Carbon Steel (CS) Outer Ring is engineered for robust sealing performance in demanding industrial applications. Specifically designed to withstand high-temperature and high-pressure environments, this gasket features a resilient spiral wound construction using V-shaped metal strips alternated with a filler material, enabling it to maintain leak-tight integrity under thermal cycling and mechanical stress. The 0.5" thickness and 150# pressure rating make it ideal for standard flange sizes, while the carbon steel outer ring enhances the gasket's structural integrity, providing firm centering and preventing flange damage. Suitable for use with steam, oil, gas, and various corrosive fluids, this gasket ensures reliable and durable sealing in refineries, power plants, petrochemical facilities, and other industrial sectors requiring high-performance sealing solutions.

The carbon steel outer ring provides additional structural support and prevents gasket over-compression during flange assembly. It also facilitates easier centering of the gasket within the flange and protects the flange face from damage.
Yes, the combination of the metal strip and soft filler material like graphite makes it suitable for many corrosive fluids. However, compatibility depends on the specific filler and metal alloy used, so it should be selected based on the fluid characteristics.
Yes, spiral wound gaskets with flexible filler materials can accommodate thermal expansion and contraction effectively, maintaining a reliable seal over repeated temperature fluctuations.
This gasket is designed to meet ASME B16.20 standards, ensuring compatibility and performance with flanges rated for Class 150 pressure.
Yes, spiral wound gaskets including the 0.5 inch 150# variety can be manufactured to custom dimensions to match specific flange sizes and requirements.
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.
