WT wrapped with heat shrinkable products for overhead and buried steel pipe Welded Joints of pipeline corrosion and heat insulation designed to fill the mouth. It is cross-linked polyolefin radiation from the base material and special hot melt adhesive sealing compound by special sealed with hot melt adhesive polyolefin substrate, the surface of steel tube and solid epoxy coating can form a good bond. WK-WT shrinking with the installation of heating, the base material in the radial contraction at the same time, in-house compound melting layer, tightly covered up in the mouth, together with the base material in the pipeline has become a form of a solid body of the anti-corrosion With excellent wear resistance, corrosion resistance, impact resistance and good anti-aging properties of light and ultraviolet.
