Pipeline corrosion
Shrink WSS sets (with) family of products for the underground and overhead steel pipe Welded Joints of the anti-corrosion and heat insulation pipelines designed to fill the mouth. It is by radiation crosslinking polyolefin substrate and specialty hot melt adhesive sealing compound formed, special sealed with hot melt adhesive polyolefin substrate, the surface of steel pipe and solid epoxy coating can form a good bond. WK-WSS shrinking with the installation of heating, the substrate in the radial contraction at the same time, internal composite layer melting, tightly covered in the meeting I Department, together with the matrix form in the pipeline corrosion has become a solid body with excellent wear resistance, corrosion resistance, impact resistance and good anti-aging properties of UV and optical.

Characteristics:
- High mechanical strength, anti-aging ability.
- Environmental stress-resistant performance.
- Adhesive performance.
- Easy to use.
