Description
System Description
The POLYKEN® 942&955 System is a multilayer coating system designed for the corrosion protection of pipelines operating in highly corrosive environments and exposed to high mechanical stresses that may be present particularly on large diameter pipes. The system consists of POLYKEN®1027 liquid adhesive, POLYKEN® 942 three-ply anti-corrosion inner layer and POLYKEN® 955 mechanical outer layer and is fully certified to the DIN 30672 and EN12068 standards.
The 3-ply adhesive system produces a strong cohesive bond 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.
Features
- Fully amalgamating overlapping areas
- Forming a sleeve-type coating
- Impermeable to oxygen and moisture
- Resistant to soil stress
- Superior in-ground performance
- Long-term in-ground performance
- Uniform coating thickness
- Plant coating quality with in-situ application
- Low cathodic protection-current requirements
- Saving cost over the life of the pipeline
- Compatible with all pipe diameters and generic plant coating systems
