Description
Overview:
Product description: The Polyken®942-AS /955 EN system is an asymmetric co-extruded multilayer coating system designed for the corrosion protection of new construction cross country pipelines / planpiping / pipeline coating rehabilitation operating in highly corrosive environments and exposed to high mechanical stresses that may be present particularly on large diameter pipes. The system consists of 1027 liquid adhesive, 942 asymmetric three ply anti-corrosion inner layer and 955 EN mechanical outer layer and is fully tested to the EN12068 Class C50 and ISO-21809-11.
The asymmetric three ply adhesive system produces a strong cohesivbond to the primed steel surface, at the spiral overlap and to the mechanical outer layer. The tough mechanical properties of the outer layer provide protection to the pipes during handling and installation. The coating system is compatible with the cathodic protection system.
Features:
- Thick adhesive layer towards the primed steel surface.
- Fully amalgamating overlapping areas.
- Impermeable to oxygen and moisture.
- Resistant to soil stress.
- Uniform coating thickness.
- Low cathodic protection-current requirements.
- Compatible with all pipe diameters and generic plant coating systems.
Benefits:
- Forming a sleeve-type coating.
- Proven long-term in-ground performance.
- Superior in-ground performance.
- Plant coating quality in-situ application.
- Saving cost over the life of the pipeline.
- Minimizes inventory, thus saving money.
