Non-Asbestos Gaskets
Compressed Non-Asbestos Gaskets (CNAF) Materials are used in high pressure and high temperature applications. Rama industrial Products Corporationis a leading supplier and manufacturer of different classes such as the Non-Asbestos Full Face & Ring Gaskets with different pressure capacities. The different application types such as piping systems use the Non Asbestos Jointing Sheets for maximum integrity. They are easy to remove from the flange assembly after use due to the anti-stick coating properties, are very economical and will withstand a temperature range from -196°C up to 450°C (grade may vary dependent upon the application) and suit- able for pressures up to 140 bar (again depending upon the grade).
