Heat Shirnk Tape designed for corrosion protection of buried and exposed steel pipelines, especially for pipelines, fiftings, bends, elbows and other irregurations. HWT is made of three layers, namely the outer layer(backing material)is a cross-linked polyolefin backing; The middle layer is high performance heat melting adhesive, polyethylene and fusion bonded epoxy. The teo-layer tape bears no primer. Upon the application of heat, HWT shrinks down to fully encapsulate the protected substrate.

1. Great Compatibility to the Pipe Coating.

2. 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.

3. Outstanding Waterproof Sealing
Composed of hot-melt adhesive of excellent performance, radiation cross linked PE and solventliss epoxy primer, the product has excellent property of anticorrosion, quick contraction, sealing and waterproof.

4. Strong Adaptability on Site
The heat shrinkable sleeve of special structure has a high shrinkage (≥ 50%), strong shear resistance and peel strength which enables it to be used in the sealing of the joint, concentric reducer, or the plugging of the crossing ends. Because of it performs well in the sealing, it is widely used.

5. Timesaving and Laborsaving Installment
The product is easy and convenient to use, thus it can ensure the quality of the installment. Because the size of the sleeve of special structure changes greatly after it shrunk, compared with that before the shrinking, the installation personnel can observe whether it is properly installed by visual inspection.
