TPEP Coated Steel Pipe

DHX offers a complete range of corrosion-resistant piping solutions, including steel pipes with a three-layer polyethylene (TPEP) coating, as well as fittings such as flanges, elbows, and tees. Our TPEP pipes feature a three-layer structure: an epoxy resin underlayer, an adhesive middle layer, and a polyethylene outer layer, providing superior corrosion resistance. The inner wall of the pipe is coated with a fusion-bonded epoxy (FBE) layer, offering excellent mechanical properties and resistance to internal corrosion, making it widely used in water supply, wastewater treatment, and the oil and gas industries.

  • Outer diameter range: 100mm – 1500mm
  • Wall thickness range: 3mm – 20mm
  • Coating type: Fusion bonded epoxy (FBE) + polyethylene (PE)
  • Maximum operating temperature: 80°C

Introduction

DHX provides one-stop piping solutions, including custom flanges, elbows, and other fittings, all coated with the same high-performance corrosion-resistant coating. Whether for underground installations, crossing overhead structures, or trenchless construction, DHX ensures seamless collaboration among all components of the piping system, enhancing safety, durability, and ease of installation.

Advantages

  • Superior Corrosion Resistance: The dual-layer coating of fusion-bonded epoxy on the interior and polyethylene on the exterior provides exceptional protection against corrosion, extending the life of the pipeline.
  • High Durability and Strength: Steel pipes offer high mechanical strength and resistance to pressure, while the polyethylene coating adds flexibility and impact resistance, making it suitable for harsh environments.
  • Cost-Effective: With a longer lifespan and reduced maintenance costs, TPEP coated pipes offer a high return on investment compared to traditional pipelines.
  • Environmental Protection: The pipes’ smooth inner surface prevents the buildup of contaminants, reducing the risk of water quality degradation, and they are resistant to chemicals and pollutants.
  • Improved Fluid Flow: The smooth inner wall also results in reduced fluid resistance, contributing to more efficient transportation and reduced energy consumption.
