Polyurethane-lined Steel Pipes

Polyurethane-lined Steel Pipes

Heavy-Duty Polyurethane-Lined Steel Pipes for Abrasive Slurry Transportation

Polyurethane-lined steel pipes are specially engineered for highly abrasive and corrosive slurry transportation systems in mining, mineral processing, dredging, power plants, and industrial applications.

The combination of:

  • High-strength steel pipe
  • Wear-resistant polyurethane lining

 

Provides:

  • Excellent abrasion resistance
  • High pressure resistance
  • Strong structural support
  • Long service life
  • Reduced maintenance cost

Compared with ordinary steel pipes and rubber-lined pipes, polyurethane-lined steel pipes offer superior wear performance and excellent impact resistance in severe operating environments.

PU-Lined Steel Pipe VS Conventional Steel Pipe

Advantages of Polyurethane-Lined Steel Pipes

 

 

  • Excellent Abrasion Resistance：PU lining provides significantly better wear resistance than ordinary steel pipes.
  • High Structural Strength：Steel pipe body ensures safe operation under high pressure conditions.
  • Long Service Life：Greatly reduces pipeline replacement frequency and downtime.
  • Reduced Maintenance Cost：Lower wear rate means lower maintenance expenses.
  • Excellent Impact Resistance：Polyurethane absorbs impact energy from abrasive particles.
  • Corrosion Resistance：Suitable for wet and corrosive environments.
  • Smooth Flow Performance：Low friction coefficient reduces energy consumption.
