Compensation pads are used to absorb pre-insulated pipe movements on L-, Z- and U-Luks, on bends, reducers, end couplings, valves, as well as at high and low hot spots.
Compensation pads consist of closed cells formed of polyethylene which completely protect the outer diameter of the pre-insulated pipe.
