Product Description
Heat Shrink Wraparound Sleeves
Wraparound sleeve with a separate closure designed for corrosion protection of buried and exposed steel pipelines. It consisting of a cross-linked polyolefin backing, coated with a protective heat activated adhesive. Once installed, the system effectively bonds and protects steel substrates and common main line pipe coatings including polyethylene and fusion bonded epoxy.
- 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
- A broad range of operating temperature specific and soil stress resistant adhesives for project specific conditions
Design Temperature
HT C 50/65
HT C 70/80
50℃/65℃-type heat-shrinkable sleeve is this Company’s leading product, which was developed in the year 2000 and was put into the market in 2001. Up till now, altogether 500 thousand sets of it have been used and there is good market feedback. It has earned recognition of and praise from each major customer.
50℃/65℃-type sleeves is easily handled, safe, fast in shrinking and short in construction time. Average operators can easily handle it. All these combined together make this product a good choice for protection coating of petroleum and natural gas pipes.
70/ 80/120℃- type heat-shrinkable sleeves is used in high temperature place, such as desert, Middle east .
We have taken a lead in China to pass the European test and get the DVGW certificate.
Standard with EN12068, DIN 30670, ASTM.
