Flange joints

Product offer

Flange joints belong to the most used structural elements since the beginning of the development of machinery. Depending on their importance and number, their proper functioning affects substantially the safety and cost-effectiveness of the facilities, as well as the emission values of companies.

Flat gasket is a key component of flange joints. Its purpose is to ensure the tightness of the joint by compensating for the unevenness of the sealing surfaces and closing the inner ducts by applying pressure to the flange joint. During operation, the specific pressure on the gasket changes and therefore new materials and construction of flat gaskets must be constantly developed to reliably maintain the required sealing class with the widest range of operating conditions. The properties of the gasket are measured and described by the characteristic values that allow leakage calculations with the tightness certificate as well as the mutual comparison of the individual gaskets on the market.
