450mm Width Heat Shrink Sheet with Closure Patch

Product Description

Uniform Shrinking TSD65 Heat Shrinkable Sheet for 3PE Steel Pipes
TSD65 Heat Shrinkable Tape with Closure Fixing Patch

Product Description

1.1 Product profile

HSS ,Two-piece, with separate closures designed for the corrosion protection.
HSS is superior performance heat shrinkable products designed for corrosion
protection on field applied girth-weld joints of buried and exposed steel pipelines
operating up to 80°C (176°F).

The inner layer is two-components epoxy primer which coated on steel pipe;
Intermediate level is special hot melt adhesive ;
Outer layer is modified radiation crossing linking polyethylene backing.

1.2 Features & Benefits:

Heat Shrinkable Sleeves provide great corrosion protection, Superior resistance to
Cathodic Disbondment and excellent durability against abrasion and chemical attack.
The result is effective, good performance of sealing, wide application, easy to operate
and preheating temperature low (50 ºC) ,long term protection against corrosion.
HSS is a wraparound sleeve with a separate closure
Cross-linked backing provides superior abrasion, mechanical and chemical attack resistance.
High performance adhesive provides excellent resistance to Cathodic
Disbondment to ensure long-term corrosion protection.
Just-in-time customized lengths allow bulk rolls to be field cut to protect any pipe size
Open sleeve configuration allows the product to be applied after the pipeline has been welded and cleaned.
