Spiral Wound Gaskets
Spiral wound gaskets are versatile sealing components used in various industrial applications. They are composed of a spiral-wound metal strip and a filler material, providing excellent sealing capabilities under high pressure and temperature. Here are the main types of spiral wound gaskets:
1. Standard Spiral Wound Gaskets
- Construction: Composed of alternating layers of metal strips (typically stainless steel) and filler material (such as graphite, PTFE, or asbestos-free materials).
2. Kammprofile Gaskets
- Construction: A combination of a spiral wound gasket and a metal core. The core provides additional strength and the sealing elements are spiral wound around the core.
3. Double Jacketed Gaskets
- Construction: Feature a metal jacket surrounding the spiral wound core, which provides additional protection and strength.
4. Inner Ring Gaskets
- Construction: Includes an inner metal ring that provides additional support and limits the radial movement of the gasket.
5. Outer Ring Gaskets
- Construction: Features an outer metal ring that helps in maintaining the gasket’s shape and position, particularly in flange
6. Compact Gaskets
- Construction: Designed to be thinner and more compact, these gaskets have a reduced profile compared to standard spiral wound gaskets.
7. Temperature-Resistant Gaskets
- Construction: Made with specialized fillers and metals designed to withstand extreme temperatures.
8. Chemical-Resistant Gaskets
- Construction: Includes fillers and metal strips that are resistant to corrosive chemicals.
- Applications: Used in industries where exposure to aggressive chemicals is common, such as chemical processing and petrochemical industries.
9. Fire-Safe Gaskets
- Construction: Designed to maintain their sealing ability even under extreme fire conditions.
- Applications: Typically used in industries where fire safety is a critical concern, such as in the oil and gas industry and in safety-critical applications.
10. Low Emission Gaskets
- Construction: Designed to minimize the leakage of gases and fluids, often incorporating specialized materials and design features.
- Applications: Used in applications where controlling emissions is crucial, such as in environmental and regulatory compliance scenarios.
