Overview of Pipe Lining Materials

LPS engineers and provides optimal internal linings for your pipeline project. The following are common internal linings that LPS works with:

Aromatic Polyurethane

  • Excellent long term resistance to water permeation
  • Very good adhesion to steel
  • Good abrasion resistance
  • Withstands stress from pigging and internal lineup clamps
  • Sufficient flexibility and elongation for thermal expansion, pipe handling & cold bends

Polyurethane per AWWA C222: Advantages vs. Epoxy

Thermoplastic Polyurethane

  • Excellent abrasion resistance & sufficient thickness for highly abrasive slurries
  • Superior physical properties (tensile, tear, elongation)
  • Very good adhesion to steel

Natural & Synthetic Rubber

  • Excellent abrasion resistance & sufficient thickness for highly abrasive slurries
  • Superior resilience and elongation
  • Excellent adhesion to steel
  • Synthetic rubbers are resistant to high temperatures & various chemicals

Fusion Bonded and Liquid Bonded Epoxy

  • Cost-efficient corrosion protection for water pipelines
  • Excellent adhesion to steel
  • Good chemical resistance

Welded Joint System for FBE Lined Pipe

Hi-Density Polyethylene

  • Very low water permeation
  • Good abrasion resistance
  • Sufficient thickness to eliminate possibility of liner pinholes
