3LPE Heat Shrink sleeve material and closures are manufactured from a thermally stabilized, ultraviolet-resistant, semi-rigid, high-density polyethylene. The 3LPE HSS backing is radiation cross-linked PE backing which provides superior abrasion, mechanical, and chemical attack resistance. And the inner surface of the sleeve is coated with a controlled thickness of a high-shear hot-melt copolymer adhesive. The high-performance adhesive provides high bond strength, high shear resistance, excellent resistance to cathodic disbondment, long-term stability and long-term corrosion protection for the linepipe joint.
FRDP weld joint Heat shrinkable sleeving enjoys good performance of sealing, wide application, easy operation and low preheating temperature, and a perfect anti-corrosion effect. It is suitable for use at the maximum design temperature of the pipeline.
Long service life: The heatshrink sleeve enjoys more than 30 years of service life and good sealing capability.
The wraparound heat shrinable sleeve belong to open tape allows it to be applied after the pipes have been welded and cleaned, it is more convenient for application than the tubular heat shrinkable sleeve.
💡 FRDP Heat Shrink Sleeve is Germany DVGW Certified and CHINA CLASSIFICATION SOCIETY certified. FRDP heat shrinkable sleeve can meet a variety of domestic and international standards, such as GB∕T 23257-2017, DEC, DIN30672, European Standard EN 12068, and EN ISO 21809-3:2016.
💡 The widest sleeve width can be offered is 1200mm and the max. length can be offered in 300M per roll.
💡 Strict quality management is carried out in accordance with ISO9001. Each batch of heat shrink sleeves is accompanied by a certificate stating the tests have been carried out on every batch and results are in accordance with the specification standard.
💡 With a professional R&D team and a National CNAS-accredited laboratory, production can be customized according to client special requirements. OEM and ODM services can be offered.
