Product Description
The heat shrinkable sleeve is made of radiation crosslinked high-density polyethylene substrate and special sealing adhesive. It has the characteristics of excellent mechanical damage resistance, good sealing and long service life. The heat shrinkable opening sleeve is widely used in steel pipe network engineering in petroleum, natural gas, chemical industry, urban construction and other industries to provide a long-term excellent and reliable anti-corrosion protection system for the position where the pipeline needs to be repaired for anti-corrosion.
Product advantages
It has the advantages of flexible and convenient use, excellent adhesion performance, high strength, wear resistance, environmental stress resistance, heat aging resistance, UV resistance, high dielectric strength and acid and alkali corrosion resistance.
● Cross-linked backing
Provides superior abrasion, mechanical and chemical attack resistance,great corrosion protection,
● With a separate closure.
Open type sleeves allows the product to be applied after the pipeline has been welded and cleaned.
● Jumbo Rolls
Just-in-time customized lengths allow bulk rolls to be field cut top protect any pipe size
● Widely temperature range
Meet the requirements of different pipeline operating temperatures,
50 Degree, HT60 Degree HT80 Degree
HT120 Degree HT140 Degree
HST 80 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.
