Wrap-around heat shrink sleeve
Product Profile
CNP 60 system is a wrap-around heat shrink sleeve which replicates the structure and the performance of factory applied three-layer PE coatings. It is installed on a welded joint by wrapping it around the welded joint of the gas & oil & water pipeline over the applied layer of epoxy primer CNP-EP in the field. The sleeve (piece of tape) is fixed on the lash with a closure patch.
Construction
First layer: Liquid epoxy, solvent-free two-component.
Second layer: High shear strength hot melt adhesive.
Third layer: Radiation cross-linked, high density polyethylene.
Features & Benefits
● CNP 60 is a wraparound sleeve with a separate closure
● Cross-linked backing provides superior mechanical and chemical attack resistance.
● CNP 60 Sleeve provide super barrier protection against corrosion,good performance of sealing, widely application range.
● High performance adhesive provides excellent resistance to Cathodic Disbondment to against abrasion and chemical attack.
● Just-in-time customized lengths allow bulk rolls to be field cut top protect any pipe size
● Dimpled backing provides a “permanent change” indicator for application when heat.
● CNP 60 can be used on the PE, FBE, Coal Tar, DFBE coatings.
● Meet for standard ISO21809,EN12068,GOST
