Lined Pipe Systems

Continuous HDPE lining of steel pipelines

The continuous HDPE lining system protects the carbon-steel pipeline from all internal corrosive elements, reduces friction, and provides substantial cost saving. A folded HDPE liner is inserted into the steel pipe and reverts to the exact internal diameter. PEXMART lined fittings are manufactured to ISO spec and pressure-tested to 1.5× service pressure.

Highlights

Rehabilitates old abrasion pipelines
HDPE lined fittings: bends, tees, concentric/eccentric, laterals
Smoother bore → superior flow, less friction
Ideal for acid water, crude oil, slurry, raffinate, effluent
Blasting & painting to prepare surfaces
