If you are looking for China golden supplier and China good supplier polyken 942 black cold applied 3-ply pipe wrapping tape, good quality and high quality polyken 942 black cold applied 3-ply pipe wrapping tape, please feel free to contact Jining Qiangke Pipe Anticorrosion Materials Co.,Ltd.
System Description
The polyken 942 black cold applied 3-ply pipe wrapping tape 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 3-ply adhesive system produces a strong cohesive bond to the primed steel surface, at the spiral overlap and to the mechanical outer layer.
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 |
