Long Term Corrosion Protection

The FBE component provides excellent adhesion to steel, providing superior long term corrosion resistance and protection of pipelines operating at moderate temperatures .If required, Low Application Temperature(LAT) FBE can be selected as the primer to ensure low preheating conditions and long term integrity of high strength steels(X80 or higher)

In addition, 3LPE systems offer an excellent resistance to cathodic disbondment, reducing lifecycle cost of cathodic protection.

Engineered Solutions

Bredero Shaw Advanced Manufacturing Systems allow for a customized 3LPE System to your specific project.

Can be applied to pipe diameters from 51 mm (2) to over 1220 mm (48).

Can be applied in a wide range of thicknesses to cost effectively meet unique project specifications and performance requirements.

Good Mechanical Protection

The tough outer PE layer protects pipelines during transportation and installation thereby reducing costly repairs while also providing added in-ground protection against shear forces, chemicals and abrasive soil conditions.

By increasing the thickness of the PE outer layer, the 3LPE System can provide a high level of mechanical protection across a variety of difficulty environments without requiring the use of costly backfill.

Global Availability

Can be manufactured at a single plant or in multiple coating plants to improve project logistics.

Through Bredero Shaw global footprint of high capacity plants clients benefit from single point of contact project management, even in the most demanding logistical configuration.
