Rubber-lined Steel Pipes

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

Rubber-lined steel pipes are widely used in mining, mineral processing, power plants, dredging, chemical industry, and industrial slurry transportation systems due to their excellent abrasion resistance, corrosion resistance, and structural strength.

The pipe combines:

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

 

This dual-layer structure provides:

  • Strong pressure-bearing capacity
  • Excellent wear resistance
  • Corrosion protection
  • Impact absorption
  • Long service life under abrasive slurry conditions

Compared with ordinary steel pipes, rubber-lined steel pipes significantly reduce pipeline wear, maintenance frequency, and operating costs in abrasive material transportation systems.

Rubber-Lined Pipe VS Ordinary Steel Pipe

Advantages of Polyurethane-Lined Steel Pipes

 

 

  • Excellent Wear Resistance：Wear-resistant rubber lining significantly improves pipeline life in abrasive slurry systems.
  • High Structural Strength：Steel pipe body provides excellent pressure resistance and structural stability.
  • Impact Absorption：Rubber lining absorbs impact energy from solid particles.
  • Corrosion Resistance：Suitable for wet and mildly corrosive environments.
  • Reduced Maintenance Cost：Longer service life reduces maintenance and replacement frequency.
  • Smooth Inner Surface：Improves slurry flow performance and reduces flow resistance.
  • Noise & Vibration Reduction：Rubber lining reduces operational vibration and noise.
