Heat Shrinkable Joint

Heat Shrinkable Joint

Heat Shrinkable Joint INTRODUCTION PE Heat Shrinkable Joint(sleeve) is composed of cross-linked polyethylene back and special heat melt adhesive. Heat melt adhesive has good bonding with PE back, steel pipe and Fusion bonded epoxy (FBE layer). By heating PE back shrinks, adhesive layer melts, and closely wraps around pipe joints, then it forms together with FBE a firm and continuous anti-corrosion body. It is resistant to corrosion, wear, impact, UV and aging, easier to be operated.

    3. The best way to weld the joint should use the Hand extruder welding the cutting edges inside of the pipe first, the use the narrow tape welding it from outside.


    1. Waterproof;
    2. Able to withstand axial forces initiated by axial movements of the pipe in the ground;
    3. Able to withstand radial forces and bending moments;
    4. Able to withstand effects of temperature and temperature variations.
    5. Have the same thickness of the line pipe insulation layer
