Polyethylene Anti-Corrosion Adhesive Tape
PRODUCT PARAMETERS
Description
Product Description
Polyethylene anti-corrosion tape is a high-performance pipe wrapping tape manufactured by thermally laminating a butyl rubber-based adhesive onto a polyethylene backing film. It is widely used for steel pipeline corrosion protection in oil, gas, water, and chemical industries.
Three Protection Levels
The tape is available in three protection levels: Ordinary, Reinforced, and Extra Reinforced. Customers can select the appropriate level for inner tape (corrosion insulation) and outer tape (mechanical protection) according to their specific requirements, forming a complete anti-corrosion system.
Key Features & Applications
- Cold application — no heating required, ready for backfilling immediately after wrapping
- Strong adhesion and excellent sealing performance
- UV resistant, aging resistant, and high compressive strength
- Non-toxic, odorless, and environmentally friendly
- Ideal for field joint coating, pipeline repair, and external pipe wrapping
System Composition
The complete anti-corrosion system consists of polyethylene anti-corrosion tape (inner layer) + polyethylene protective tape (outer layer) + anti-corrosion primer. The primer fills surface irregularities and enhances bonding strength between the tape and steel pipe.

Installation Guide & Precautions
Two Installation Methods
The polyethylene anti-corrosion tape can be applied by manual wrapping or mechanical wrapping machine, depending on project scale and site conditions.
Quick Installation Steps
- Surface preparation: Remove rust to Sa2.5 (blasting) or St3 (manual).
- Primer application: Apply anti-corrosion primer evenly on the prepared steel surface.
- Tape wrapping: Wind the tape spirally with 50-55% overlap, maintaining uniform tension.
- Inspection: Check for smooth overlap edges, no bubbles, wrinkles, or lifted ends.
Key Reminders
- Backfilling can be done immediately after wrapping — no curing time required
- For mechanized wrapping, adjust the tensioner to apply proper tension
- Store in a dry, cool place between -10°C and 35°C, avoid direct sunlight
