Dn24'' Heat Shinrkable Wraparound Sleeve
Heat shrinkable sleeve (2 layers), which are developed and manufacture for Anti-corrosion of pipeline, are the composition of radiation cross-linked Polyethylene backing and high shearing strengthen melt adhesive, and have The function of shape memory. The hot melt adhesive is squeezed into the Joint by the shrink power to form a perfectly sealed surface, after being Heated. It is compatible with standard pipe coating, also can be used for Coating bare, replacement pipe section and large radius bends. The system Is designed to be applied with minimum preheating and is ideal for large Diameter wastewater pipe.
Feature
Fast shrinkage speed, good waterproof performance, good anti-corrosive Performance, long service life, convenient transportation and fast Construction. The product are ideal material for corrosion prevention and Insulation.
Application scope
It's mainly used for heat pipe network, steel pipe corrosion resistance and Insulation, chemical pipes and sewage pipes etc.
Used for protection of welded joints of oil, water & gas pipelines from Mechanical damage & corrosion.
