Pre Insulation Pipe Joints Corrosion Protection HDPE Heat
Shrinkable Sleeves
Usage
Radiation cross-linked Polyethylene (PE) Heat Shrinkable Sleeve is
mainly used in anti-corrosion, repairing of oil gas pipeline,is fit
for 3PE oil gas steel pipe, 2PE steel pipe, thermal insulating
pipe, Epoxy powder coating, and PE drainage pipe etc. We have
National Patent certifications.
Advantage
Radiation crosslinked PE heat shrinkable sleeve is made by basic
material and melt adhesive. Our product is with strong adhesion to
make sure good quality of project; easier operation, quick
shrinking, low cost, perfect anti-water permeating, anti-chemical
corrosion, good insulativity and aging resistance, is ideal
material of anti-corrosion and thermal insulating system.
EVA is imported. Brand Matsui Japan or Dupont USA
We sold it to Vietnam,Sudan, Kenya, Russia, Kazakhstan,Australia,
Turkey etc.

backing.
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 °C) ,long term
protection against corrosion.
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.
