Heat Shrink Sleeves

The heat shrink sleeve has the two-piece structure. Together with the primer, the three-layer coating system is formed. The inner layer is two-component epoxy primer which is coated onto the steel pipe. The intermediate layer is the special hot melt adhesive. The outer layer is the modified radiation cross linked polyethylene film backing. The product is designed specially for corrosion protection for girth-weld joints of buried or exposed steel pipelines. It is widely applied and operated easily.

Features
1. The heat shrink sleeve is produced with a separate closure. The open type design allows the product to be applied after the pipeline is welded and cleaned.
2. The product can provide great sealing effect and long term corrosion protection for pipeline for its superior resistance to cathodic disbondment as a result of the high performance adhesive.
3. Due to the cross-linked film backing, the product has excellent durability against abrasion as well as mechanical and chemical attack.
4. The preheating temperature for the product is low to 50℃ and the maximum operating temperature is up to 80℃.
5. The product with bulk roll can be cut instantly in length to fit the pipe with different size.
