O-Liner

For operators of industrial oil pipelines, the corrosive effect of the raw material is one of the biggest challenges.

The O-Liner is a quick solution for rehabilitating pressure pipelines that also acts as a protective barrier between oil and pipe. Its media-specific inner layer made of thermoplastic polyurethane (TPU) is particularly corrosion-resistant.

The Primus Line O-Liner is suitable for the following applications in the oil sector:

Crude oil
Refined petroleum products
Process water
Diesel
Jet A1
Kerosene
