3PE Coated Steel pipe

3PE Coated Steel Pipe - Industrial Anti-Corrosion Pipeline Solution

Product Overview

Our 3PE Coated Steel Pipe features a three-layer polyethylene coating system that meets API 5L and EN 10219 dual standards. The coating consists of fusion-bonded epoxy primer (>100μm), copolymer adhesive layer (170-250μm), and high-density polyethylene outer layer (1.8-3.7mm). With JSFITTINGS's 42-year manufacturing expertise and 30,000-ton annual capacity, you get reliable anti-corrosion protection that extends pipeline service life to 50+ years in harsh soil environments. Our precision-engineered coating process delivers peel strength exceeding 80 N/cm at 20°C and operates efficiently from -40°C to +80°C.For higher temperature requirements up to 110°C, we also offer 3PP (Polypropylene) coating options.

Key Features & Advantages

30,000-Ton Production Guarantee

You benefit from stable supply chains for large-scale projects with our dedicated production capacity and Central Asia/Middle East logistics network.

Dual-Standard Compliance

Your projects meet international requirements with API 5L and EN 10219 certifications, plus DIN 30670 and ISO 21809-1 coating standards.

Active-Passive Protection System

You get dual-layer security - even with outer layer damage, the inner epoxy prevents corrosion creep and maintains structural integrity.

Precision Coating Application

You receive uniform wall thickness and precision-engineered beveling through our 100-meter automated painting lines and controlled sandblasting systems.

Chemical Resistance Superior Performance

Your pipelines resist soil chemicals, fungus, and moisture with cathodic disbondment radius ≤7mm after 48h at 65°C testing.

FAQ

Q: What's the difference between 3PE and 3LPE coating?

A: 3PE and 3LPE refer to the same three-layer polyethylene coating system. Both terms describe identical anti-corrosion technology.

Q: Can you apply coating to existing steel pipes?

A: Yes, we can apply 3Pe Coated Steel Pipe coating to seamless, welded, stainless steel, and alloy steel pipes per your specifications.

Q: What's your minimum order quantity?

A: Our minimum order is typically 25 tons, but we accommodate smaller quantities for specialized projects.

Q: How do you ensure coating adhesion quality?

A: We maintain strict surface preparation standards, controlled application temperatures, and conduct peel strength testing on every production batch.
