3PE HT65 Heat shrink sleeves
Forever heat shrink tsleeves consists of a crosslinked polyolefin backing, coated with a protective, heat active anti-corrosion adhesive which effectively bonds to steel substrates and common pipeline coatings including polyethylene and fusion bonded epoxy.
HT60 is superior performance heat shrinkable products designed for corrosion protection on field applied girth-weld joints of buried and exposed steel pipelines operating up to 65°C.The inner layer is two-components epoxy primer which coated on steel pipe; Intermediate level is special hot melt adhesive ;Outer layer is modified radiation crossing linking polyethylene backing.
The product is well above the domestic anticorrosive professional standards and reaches the standard requirement of EN12068，DIN 30672，ISO 21809-3 and ASTM as well.
The epoxy Primer is a corrosion protection layer to improve cathodic disbonding resistance, which is applied to cleaned and dry steel surface.
Features & Benefits
Heat shrink 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.
HT 65 is a wraparound sleeve 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.
