3LPE COATED PIPE

3LPE coating pipe

3LPE coating pipe is designed to provide enhanced protection for steel pipes used in various applications, particularly in corrosive or challenging environments. The three layers typically consist of:

Layer 1: Epoxy Primer - This layer provides excellent adhesion to the steel surface and acts as a corrosion inhibitor.

Layer 2: Copolymer Adhesive - This layer serves as a tie layer between the epoxy primer and the outer layer of polyethylene. It provides resistance to cathodic disbondment and ensures the long-term integrity of the coating system.

Layer 3: Polyethylene - The outer layer of polyethylene offers mechanical protection and serves as a barrier against moisture and harsh environmental conditions.

3LPE coating pipe are commonly used in the oil and gas industry, water pipelines, and other applications where protection against corrosion and mechanical damage is essential.

Features of 3LPE coating pipe :

1. Excellent chemical and corrosion resistance preventing steel pipes from any damage.
2. Resistance to cathodic disbondment
3. The external layer of polyethylene prevents any physical damages to either the pipes or the fusion bonded epoxy during handling
4. The 3LPE coating pipes have high performance characteristics and an extended life cycle.

Standards used in manufacturing 3LPE coating pipe are:

• DIN 30670
• CSA Z245.21
• AS 4321
• IS 3581
