The new LineSeal flange gasket has been specially designed by PSI for use in extreme critical service when Zero Emission is essential. LineSeal® gaskets are suitable for use as a high quality sealing gasket for harsh service and/or as part of high quality flange isolation kit. The LineSeal® gasket is designed for all pressure class flanges and used throughout Oil, Gas and Petrochemical industries as a problem solver. Advanced features of the LineSeal® gasket include a stainless steel core for strength, bonded between G-10 laminates incorporating a proven spring energized seal element. Unsurpassed for sealing and electrical isolation it is manufactured in accordance with stringent ISO 9001 standards.
- Lowest possible clamp and compressive load.
- Increases gasket life.
- Materials such as Kel-F, olyimide, TFE (Teflon) and vinyl may be used as sealing elements which dramatically increases the options available for matching gasket materials to service and environmental conditions.
- This greater variety of materials also provides excellent temperature and chemical range compatibility.
- Linebacker sealing gaskets incorporate near zero m and y factors that make it possible to effect a positive seal without tremendous bolt loads that are required with flat gaskets.
- Type E and F sealing and insulating gaskets may be fabricated to any diameter.
- Linebacker gaskets may be ordered as part of a complete flange insulation kit.
- Linebacker gaskets Eliminates flange leaks.
- Guards against blowouts, and protects against fire and hostile environments.
