Products Expansion joints

Definition | Expansion joints

A STENFLEX® expansion joint is a flexible element for compensating for a wide range of movements in piping systems. In particular, it is used to offset thermal expansion, assembly inaccuracies and to reduce noise and vibrations in fittings, pumps and apparatus. 

Construction

STENFLEX® expansion joints comprise an elastic bellows and two connecting elements (e.g. flanges, welding ends or screw connections). Depending on the application, universal expansion joints, expansion joints with tie rods or with joint bracing are used. For special requirements, all STENFLEX® expansion joints can be equipped with inner conduits or an outer protective jacket.

Universal use

STENFLEX® expansion joints can be used everywhere in all industrial sectors. They are used, for example, in water treatment plants, on motors, pumps or emergency power generators as well as in air conditioning and heating systems.
