The damaging of insulation material in district heating pre-insulated pipes is a very recurrent issue, due to the thermal and mechanical expansions caused by the different temperatures of the flowing water in the tube.
LK2 provides an effective solution for the recovery, based on the action of different materials supplied by CANUSA-CPS allowing a prompt solution and damage prevention. The selected materials do not affect the cathodic protection, guaranteeing the complete joint sealing and an excellent resistance to the mechanical stress.
