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

Compressibility

Recovery

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.
