TPEP Anti-Corrosion Steel Pipe
Excellence in High-Performance Pipeline Anti-Corrosion Technology
Product Overview
TPEP anti-corrosion steel pipe is a high-performance pipeline featuring dual protection technology with Three-Layer Polyethylene (3PE) and Fusion Bonded Epoxy (FBE) coatings, specifically designed for underground or overhead transportation in harsh environments. With its exceptional anti-corrosion performance and mechanical strength, it is widely used in petroleum, natural gas, chemical, and water supply industries, making it the ideal choice for long-distance transportation pipelines.
Three-Layer Composite Anti-Corrosion Structure
Fusion Bonded Epoxy (FBE)
Applied directly to the steel pipe surface, providing excellent adhesion, chemical corrosion resistance and anti-cathodic disbondment properties. Thickness typically ranges from 150-400 microns.
Adhesive Layer (AD)
Enhances bonding between FBE and polyethylene layers, ensuring overall integrity of the anti-corrosion coating. Thickness generally ranges from 170-250 microns.
Polyethylene Layer (PE)
Provides mechanical protection and waterproofing performance with high impact resistance and wear resistance. Thickness ranges from 1.5-3 millimeters according to requirements.
Core Advantages
