Product Overview

Our 3PE (Three-Layer Polyethylene) Anti-Corrosion Coated Seamless Steel Pipe combines the structural strength of premium seamless carbon steel with a state-of-the-art triple-layer protective coating system. This advanced coating technology provides unparalleled protection against corrosion, mechanical damage, and chemical attack, making it the industry standard for buried oil, gas, and water pipelines worldwide. Designed for a service life exceeding 50 years in underground environments, our 3PE coated pipes represent the ultimate solution for long-term pipeline infrastructure.

Key Features & Advantages

• Triple-Layer Protection System: Layer 1 - FBE (Fusion Bonded Epoxy) primer provides excellent adhesion and cathodic disbondment resistance; Layer 2 - Copolymer adhesive ensures strong inter-layer bonding; Layer 3 - High-density polyethylene outer layer delivers mechanical protection and moisture barrier.
• Exceptional Corrosion Resistance: The 3PE coating system withstands harsh soil conditions, stray currents, microbiological corrosion, and aggressive chemical environments, with proven performance in both arid and high-moisture terrains.
• Multiple Coating Options: Also available with 2PE, 2PP, 3PP, and FBE-only coating systems to match specific project requirements and budget considerations.
• Seamless Base Pipe: Premium API 5L compliant carbon steel pipe with tensile strength min 415 MPa ensures structural integrity for high-pressure pipeline operations.
• Cathodic Disbondment Resistance: FBE primer layer ensures less than 5mm disbondment radius at 65°C/28 days per CSA Z245.20 and DIN 30670 standards.
