Due to the industry's need for sage, effective sealing solutions to meet the demands of increasingly demanding applications, Flexitallic invented the spiral wound gasket in 1912. These products are a crucial part of industrial sealing solutions, renowned for their high quality and superior performance.

Product Types

• Standard Spiral Wound Gaskets: Suitable for general industrial applications, offering fundamental sealing performance. 
• CG and CGI Type Spiral Wound Gaskets: Designed for specific flange designs and operating conditions, with CGI type typically equipped with an inner ring for additional compression and sealing performance.
• Special Application Gaskets: Such as Thermiculite® gaskets, made with heat-treated Inconel X-750 material, suitable for extreme temperature and pressure conditions.
• Low Emission Gaskets: Specifically designed for stringent fugitive emission requirements, such as those in the oil and gas industry.

Application Fields

• Oil and Gas Industry: Provides sealing in high-pressure and high-temperature environments.
• Chemical Industry: Used for reactors, storage tanks, and pipeline systems requiring sealing.
• Power Industry: Including high-temperature and high-pressure applications in thermal power generation and nuclear power stations.
• Heat Exchanger Applications: Special gasket designs, such as the HE-CGI type, for TEMA flanges.
