Overview of 3LPE Coated Pipe

A 3LPE Coated Pipe (Three-Layer Polyethylene Coated Pipe) is a high-performance steel pipe coated with three protective layers: an epoxy primer, an adhesive layer, and a polyethylene (PE) top layer. This coating system provides exceptional corrosion resistance, high mechanical strength, and superior durability, making it ideal for oil & gas pipelines, water transmission, and underground applications.

Key Features of 3LPE Coated Pipe

Excellent corrosion resistance for underground and underwater pipelines
Strong adhesion to steel surfaces, preventing coating failure
High resistance to impact, abrasion, and mechanical stress
Superior chemical resistance against acids, alkalis, and saltwater
Longer service life compared to conventional coatings

This guide will cover everything about 3LPE Coated Pipes, including manufacturing processes, specifications, applications, price trends, and benefits.

3LPE Coated Pipe Manufacturing Process & Quality Control

How Is 3LPE Coated Pipe Manufactured?

The Three-Layer Polyethylene (3LPE) coating process involves applying three protective layers onto a steel pipe to create a highly durable, corrosion-resistant, and mechanically strong pipeline. Below is a step-by-step breakdown of the 3LPE Coated Pipe manufacturing process:

1. Surface Preparation

  • The steel pipe is cleaned using shot blasting or sandblasting to remove rust, scale, and contaminants.
  • A roughened surface is created to improve adhesion of the 3LPE coating.

2. Application of the Three-Layer Coating

The 3LPE coating system consists of three distinct layers:

Layer 1: Fusion Bonded Epoxy (FBE) Primer

  • A fusion-bonded epoxy (FBE) layer is applied to the pipe’s surface.
  • This provides excellent corrosion resistance and strong adhesion to the steel.

Layer 2: Adhesive Layer

  • A special adhesive is applied over the FBE layer.
  • This acts as a bonding agent between the FBE primer and the polyethylene top layer.

Layer 3: Polyethylene (PE) Outer Layer

  • A high-density polyethylene (HDPE) or medium-density polyethylene (MDPE) layer is extruded onto the pipe.
  • This provides mechanical protection, impact resistance, and UV protection.

3. Curing & Hardening

  • The coated pipe is allowed to cool in a controlled environment to ensure proper hardening and chemical bonding.
  • This step guarantees that the coating remains durable, flexible, and resistant to cracking.

4. Quality Control & Testing

  • Coating Thickness Measurement ensures the required thickness is achieved.
  • Adhesion Testing verifies the bond strength of the three layers.
  • Impact Resistance Testing ensures the coating can withstand mechanical stress.
  • Salt Spray & Corrosion Resistance Testing assesses long-term durability in harsh environments.

5. Final Inspection & Packaging

  • Pipes are visually inspected for uniformity, coating defects, and quality standards.
  • Each pipe is marked with batch numbers, coating specifications, and manufacturer details for full traceability.
  • Pipes are then bundled, packed, and prepared for shipping.

Why 3LPE Coated Pipes Are Preferred?

Superior resistance to corrosion, moisture, and extreme temperatures
High mechanical strength, preventing damage during transportation and installation
Strong adhesion to steel, preventing coating failure
Longer lifespan compared to conventional coatings
Ideal for underground, offshore, and high-pressure applications

Cangzhou Spiral Steel Pipes Group Co., Ltd ensures strict compliance with ISO, API, and ASTM standards for high-quality 3LPE Coated Pipes.
