Heat shrink sleeve
Heat shrink sleeve
Components for pipeline construction or repair. Heat shrink sleeves are used for pipeline joints closure in adverse conditions: in rain or snow, in deep forest or on the bottom of a pit. Being heated with a torch, the sleeve shrinks and wraps the joint tightly. After that, a hole is made in the sleeve to pour the foam package inside. The contents foam up building a PUF insulation layer.
