Croppable Heat Shrink Wrap Tape For Pipe Corrosion Protection
Description
heat shrink tape is a special accessory for heat-shrinkable wraparound sleeve PE.
heat shrink tape consists low pre-heated special rubber adhesive and thick-wall irradiated cross linked polyolefin. When heated the backing layer shrinks and the adhesive flows and forms a reliable corrosion protection seal onto metal and adjacent coating surfaces.It installed by wrapping the tape on the pipe joints ,fittings ,bends ,elbows etc .After the shrinking of the tape ,the closure patch should be installed onto the overlap of the tape.
Heat shrink tape have mainly three types, it suitable for pipe operating temperature, 60 ℃,80 ℃ and 120 ℃
Features & Benefits
●Heat shrinkable wrap Sleeves provide great corrosion protection,
Superior resistance to Cathodic Disbandment and excellent
durability against abrasion and chemical attack. The result is
effective, good performance of sealing, wide application, easy to
operate and preheating temperature,,long term protection against
corrosion.
● with a separate closure
● Cross-linked backing provides superior abrasion, mechanical and
chemical attack resistance.
● Excellent resistance to Cathodic Disbondment to ensure long-term
corrosion protection
● Just-in-time customized lengths allow bulk rolls to be field cut
top protect any pipe size
● Open sleeve configuration allows the product to be applied after
the pipeline has been welded and cleaned.
