Double-Layer Heat-Shrinkable Sleeves, Tapes & Cuffs for GOST-Compliant Pipeline Protection
Russian Standard GOST R 51164-98 | PE Backing + Hot-Melt Adhesive | Field Joint & Weld Seam Corrosion Protection
Product Overview
Our Double-Layer Heat-Shrinkable Sleeves, Tapes, and Cuffs are a family of cold-to-warm applied corrosion protection products designed for field weld joints on steel pipelines, fully compliant with Russian Standard GOST R 51164-98 and related GOST requirements. The product range includes wraparound sleeves, continuous heat-shrinkable tapes, and pre-formed cuffs, all sharing a common two-layer construction: a radiation cross-linked polyethylene backing and a hot-melt adhesive layer.
These products are engineered for pipeline operators and contractors working in Russia, Central Asia, and other regions where GOST compliance is a mandatory project requirement. The double-layer construction provides reliable corrosion protection for operating temperatures up to 60°C (standard grade), with higher-temperature variants available for demanding service conditions.

Description |
Typical Application |
| Heat-Shrinkable Sleeve |
Wraparound sleeve with separate closure patch |
Field joint corrosion protection on pipes with PE/PP factory coating |
| Heat-Shrinkable Tape |
Continuous roll for spiral wrapping |
Weld seams, irregular configurations, and repair areas |
| Heat-Shrinkable Cuff |
Pre-formed tubular sleeve (no closure required) |
Field joints where a seamless, closed configuration is preferred |
All three product forms share the same two-layer system construction and are qualified to the same GOST performance framework.
System Construction
| Layer |
Component |
Function |
| Backing |
Radiation cross-linked, thermally and light-stabilised polyethylene |
Mechanical protection, moisture barrier, shrink memory, UV stability |
| Adhesive |
Hot-melt adhesive (polymer-modified bitumen or equivalent) |
Bonds to steel and compatible plant coatings; seals the joint against moisture ingress |
The backing is cross-linked by electron beam irradiation, providing the shrink force and thermal stability required for field application. The adhesive is formulated to flow under heat and form a continuous bond to the prepared steel and adjacent plant coating.
GOST Compliance Framework
GOST R 51164-98
GOST R 51164-98 ("Steel main pipelines. General requirements for corrosion protection") is the primary Russian standard governing pipeline corrosion protection systems, including heat-shrinkable field joint coatings. The standard specifies requirements for:
-
Coating system performance and durability
-
Surface preparation requirements (Sa 2½ per GOST R ISO 8501-1 for heat-shrinkable tapes requiring preheat )4
-
Compatibility with cathodic protection systems
-
Quality control and acceptance criteria
Our double-layer heat-shrinkable products are manufactured and tested to meet the requirements of this standard, and are suitable for use in pipeline systems where GOST R 51164-98 compliance is specified.

Application Summary
Surface Preparation: Clean the steel cutback to Sa 2½ per GOST R ISO 8501-1 (for systems requiring preheat) . Remove dust, oil, and contaminants.
Preheat: Preheat the steel surface to the manufacturer's recommended temperature.
Apply Primer (if specified): Apply two-component epoxy primer to the steel only.
Position Product: Wrap the sleeve or tape around the joint, or slide the cuff into position. For sleeves, secure the closure patch.
Shrink: Apply heat uniformly with a propane torch, working from the center outward, until the backing shrinks and adhesive flows at the edges.
Inspect: Verify complete shrinkage, adhesive flow, and absence of voids or lifted edges.
