Product Description

DN36''Heat Shinkable Wraparound Sleeve for Girth-Welding Area Corrosion Protection

Heat shrinkable tape has a two-layer structure (polyethylene backing and hot-melt adhesive). When the tape is being heat, the backing of the tape shrinks, the adhesive layer softens and fills in all the irregularities to constitute a uniform coating and provide with excellent peel and dielectric strength of the coating.

Features & Benefits:                                                

1. HSWS is a wraparound sleeve with a separate closure
2. Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.
3. High performance adhesive provides excellent resistance to Cathodic   Disbondment to ensure long-term corrosion protection.
4. Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size
5. Easy to operate and preheating temperature low (50 ºC)
6. Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.

The tape is delivered in 30, 40 or 50 running meter rolls, and the thickness is usually in 1.2mm-2.5mm.
