An inner liner will contain the fluid transported by the pipeline and provide internal resistance to corrosion and erosion, protecting the reinforcing layers.
The choice of liner depends on the fluid. For dry gas, HDPE may be used, whereas for sour crude a thin liner of Corrosion Resistant Alloy may be used. The pipe design can also allow for the incorporation of heating for waxy fluids.
A key benefit of our technology is that the fluid containment layer can be optimised for the chemical nature and temperature of the fluid to be transported, without having to compromise on the mechanical pressure resistance of the pipe structure.
Radius HDPE pipe has been selected for ambient temperature gas pipelines and tested with SPS proprietary HSS reinforcement system up to 120bar.
For high temperature applications PVDF or PPS can be used up to 140C.
