2PE Heat Shrinkkable Sleeve With Closure Patch For Joint Wrap Coating

Product Profile

Two Layer Heat shrink sleeve system refers to a type of protective coating used primarily for corrosion protection of pipelines and other metal structures. The "two-layer" designation indicates that the system consists of two distinct layers, usually comprising:

1. Inner Layer: Typically made of a mastic adhesive that provides excellent adhesion to the metal surface and acts as a barrier against moisture and corrosive substances.

2. Outer Layer: Usually made of cross-linked polyethylene (PE), this layer serves as a protective barrier against physical damage, UV radiation, and environmental factors. The outer layer is often heat-shrinkable, meaning it can be shrunk to fit snugly around the surface it is protecting when heat is applied.

Key Features of a 2LPE System:

• Corrosion Protection: The combination of the epoxy and polyethylene layers provides robust protection against corrosion, which is crucial for maintaining the integrity of pipelines, especially those buried underground or submerged.

• Durability: The polyethylene outer layer is resistant to various environmental factors, including moisture, chemicals, and UV light, enhancing the longevity of the coating.

• Application: The heat-shrinkable nature of the sleeve allows for easy installation over irregular surfaces and joints, providing a tight fit that minimizes the risk of moisture ingress.

• Versatility: 2LPE systems can be used in various applications, including oil and gas pipelines, water pipelines, and other metal structures that require protection against corrosion.

• Ease of Inspection and Repair: The system allows for easy inspection and repair, as the outer layer can be removed if necessary, and the inner layer can be assessed for any corrosion issues.

Installation Process:

1. Surface Preparation: The metal surface must be cleaned and prepared to ensure proper adhesion of the inner layer.

2. Application of Inner Layer: The fusion-bonded epoxy is applied to the cleaned surface, creating a strong bond.

3. Positioning the Outer Layer: The heat-shrinkable polyethylene sleeve is positioned over the inner layer.

4. Heat Application: Heat is applied to the sleeve, causing it to shrink and conform tightly around the pipe or structure, ensuring a robust seal.

5. Cooling and Inspection: After application, the sleeve is allowed to cool, and the installation is inspected for any defects or areas that may require additional attention.

Conclusion:

The 2LPE system is an effective solution for protecting metal surfaces from corrosion and environmental damage. Its two-layer design combines the advantages of both epoxy and polyethylene, making it a popular choice in various industrial applications.
