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
