The Flex-O-Form® gasket programme from Simrit covers a whole range of applications. Sealing of detachable connections to pipes, containers, units etc. is achieved using static seals. The function of the seal is to compensate for unevenness in the sealing surfaces and slight movement such as heat expansion and vibration in the overall system. The most common type of static seal for such disconnection points are gaskets. With the gasket materials Flex-O-Form S and P two types of material with specific properties are available, in particular for the chemicals industry. Flex-O-Form® S...

From a standard design to an individual solution The gasket materials described above form the basis for a wide range of punched and turned seals. Thanks to the range of dimensions offered by Flex-OForm S and P sheeting and foils single-part gaskets with large diameters are possible. In addition, there are dimensional ranges which call for a customised solution. Examples of requirements ■ sealing for heads of tubular heat exchangers ■ heat exchanger subject to permanent slight vibration ■ increased service life in comparison with conventional gasket ■ dimensional range of 2000 mm exceeding...
