Types of S.P. Gaskets Insulation Kit Gaskets
- Specifically designed for RTJ (Ring Type Joint) flanges.
- Fits directly into the grooves of RTJ flanges.
- Available in oval and octagonal designs.
- Conforms to ASME B16.20 standards, ensuring a reliable seal.
- Designed for full-face flanges.
- The central gasket's diameter matches the flange's outside diameter, ensuring easy alignment during installation.
- Typically made from neoprene-faced phenolic or other reinforced materials for durability and flexibility.
- Designed for raised-face flanges.
- The central gasket is placed inside the flange bolt circle and sits on the raised face of the flange.
- Suitable for use in API, ANSI B16.5, DIN, and BS standards.
