Radiation Crosslinked Polyethylene Anticorrosion Heat Shrinkable Patch

The product is lap joint, normally applied after the line welding.

1) Structural Description

The on-site joint wrap tape is made of three layers, namely the inner layer is binary solvent free epoxy primer, the middle layer is hot-melt adhesive, the outer layer (backing material) is radiation cross linked PE. The two-layer tape bears no primer.

2) Specification

Proper Pipe Diameter Backing Material Adhesive

≤ 400 ≥ 1.2 ≥ 0.8 > 400 ≥ 1.5

3) Property and Advantages

The product is heat shrinkable patch (normally named as lapping or open heat shrinkage patch) with shrinkable ≥ 15%m and a stator, which is usually applied to repair the large-scale damage or defect of the duct joint or anticorrosion layer.

Great Compatibility to the Pipe Coating

The product is applied to the anticorrosion coating of all types of pipes such as: 2PE, 3PE, 3PP, FBE, insulation jacket, coaltar enamel, and petroleum asphalt. It has been used widely in the joint anticorrosion works on the pipelining site with satisfactory effect, which has been proved in many pipeworks.

Strong Creep and Aging Resistance

Used together with high quality hot-melt adhesive and primer, the product of our company is able to adapt to different kind of operating temperature, with strong creep resistance and a service life as long as that of the pipe.

Low Preheating Temperature

Adoption of the new material and technology extends the application range of the product in on-site joint anticorrosion. Our company has solvent free epoxy primer of super adaptability which can be applied in coating the joint at the preheating temperature of 55Celsius-60Celsius. This enables the product to be used promptly with strong peeling strength, making the operation more convenient.
