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:
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.
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.
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.
Surface Preparation: The metal surface must be cleaned and prepared to ensure proper adhesion of the inner layer.
Application of Inner Layer: The fusion-bonded epoxy is applied to the cleaned surface, creating a strong bond.
Positioning the Outer Layer: The heat-shrinkable polyethylene sleeve is positioned over the inner layer.
Heat Application: Heat is applied to the sleeve, causing it to shrink and conform tightly around the pipe or structure, ensuring a robust seal.
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.
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.
