High Strength Anti-Corrosion & Sealing PE Pipe Joint Wrapping Tape for Oil & Gas, Municipal Pipeline Field Joints

Product Description

System Overview

The double-sided butyl rubber adhesive tape is a cold-applied material designed as the inner layer of a multi-ply pipeline coating system. It is primarily used for the corrosion protection of oil, gas, and water pipelines, either underground or aboveground.

A liquid adhesive primer is recommended before application. The primer forms an initial anticorrosion barrier and creates a smooth, uniform surface to ensure strong adhesion of the double-sided tape to the pipe. The typical installation sequence is:

1. Apply liquid adhesive (primer).

2. Wrap the double-sided adhesive tape (inner layer).

3. Apply the outer protective tape.

 

Structure

The tape consists of four layers:

1. Internal adhesive layer: butyl rubber

2. External adhesive layer: butyl rubber

3. Film backing: special blended polyethylene

4. Interleaving: siliconized release film

Different models (e.g., T-430, T-435, T-440, T-450) are available with varying thicknesses.

 

Features & Benefits

• Uniform thickness and consistent adhesion

• Long-term underground performance and durability

• Excellent resistance to cathodic disbondment

• High flexibility and conformability to pipe surfaces

• Cold-applied, easy and safe installation
