Installation Upon receipt ensure that the mating flange set consists of the correct number of gaskets and fasteners. The mating flanges should be attached to the designated piece of pipework by the appropriate method of connection i.e. screwed or welded. If welding ensure that an appropriate procedure is selected to suit the flange and pipe material. When installing the flanges please bear in mind that the gasket material has the following properties for a thickness of 1.5 mm: Specific gravity 1.5 Compressibility 7% - 14% Recovery 55% Stress relaxation 30 N/mm². It is the responsibility of the installer to ensure that, dependent on the number of fasteners, the gasket material is not under/over tightened as it is torque sensitive. Flange fasteners should be tightened in diametrically opposed sequence, as shown below.
