Characteristic |
|
| |
| 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. |
| The product has three-layered structure, they are heat-melting adhesive, radiation cross-linked polythene based material. The material’ s capacity is good. |
| Conveniently installed, and easily operated. |
| The heat-shrinkable sleeve has good mechanical capacities, such as enduring abrasion, resisting impact, and preventing penetration. Easily adapts itself to the environment. |
