GAMBITGRAF LUX® Sheet

GAMBITGRAF LUX®

Series: GAMBIT AF Special

A gasket sheet designed to work in high temperatures and pressures, providing reliable sealing in demanding operating conditions. Recommended for use with steam, hydrocarbons, and most chemicals, excluding strong oxidizers. It features high resistance to mechanical and thermal loads, effectively withstands sudden temperature changes and operating cycles.

The GAMBIT AF Special series consists of advanced gasket sheets designed to work in extreme conditions, such as very high or low pressures and temperatures, as well as exposure to aggressive media. Each model in this series has been specially adapted for specific applications, such as steam installations, exposure to acids, and operation under intense thermal and pressure loads, ensuring maximum durability and reliability in demanding industrial environments.

Technical Specification - Graphite Foil Reinforced with Perforated AISI 316L Steel Sheet

Material and Composition

Gasket sheet made of expanded graphite with a purity of 99.5%, reinforced with perforated AISI 316L steel sheet with a thickness of 0.1 mm. It is characterized by low sulfur content (max. 300 ppm) and chlorides (max. 50 ppm), providing high chemical resistance and stability in extreme working conditions.
