Item Name : |
Heat Shrinkable Sleeving for Corrosion Protection of Pipelines |
Description : |
Accessories
1. Heat Shrinkable Sleeve with adhesive
2. A piece of lacquer
Characteristic:
1. Designed for corrosion protection and thermal insulation of the buried or exposed pipelines’ weld joint. Also for the air-proofing and corrosion protection of the pipelines’ flange joint and hoop part.
2. The product has three-layered structure, they are heat-melting adhesive, radiation cross-linked polythene based material. The material’ s capacity is good.
3. Conveniently installed, and easily operated.
4. The heat-shrinkable sleeve has good mechanical capacities, such as enduring abrasion, resisting impact, and preventing penetration. Easily adapts itself to the environment.
