HSS PP Polypropylene Heat Shrinkable Sleeve 3 layer dry film application ISO21809-3 14D-1

HSSPP Polypropylene Heat Shrinkable Sleeve/3 layer/dry film application/ISO21809-3 14D-1

-Field joint coatings for 3-layer PP coated pipes

HSSPP Heat shrinkable wrap-around sleeve 3-layer system is engineered for special need of corrosion protection for high operation temperature pipeline joints. Once installed, the system effectively bonds and protects steel substrates and common main line pipe with coatings such as PP or other coatings. Especially applied for rapid installation requirement under higher stress conditions caused by elevated temperatures.

Construction: Tri-layer system

First layer:  FBE or CP-3 epoxy primer (sleeve installed after epoxy primer cured)

Second layer:  High copolymer hot-melt adhesive

Third layer:  Radiation cross-linked polypropylene backing

Features & Benefits

• Excellent multifunctional adhesive allow for lower installation pre-heat temperature and super bonding to coating.

• Superior cathodic disbondment and hot water immersion resistance offers the optimum barrier long term protection against corrosion.

• Easy field installation, saves time & cost, HSS PP can be installed quickly and easily in most environments

• Covers wide range of operating temperature ratings, offers a solution for nearly every application.
