Fixed extrusion plant coiling and reeling machinery using Low Ovality Technology plus newly developed transport trailers also allow free standing coils or reels up to DN250 x 250m to be transported without vehicle escorts. Pipe is supplied in coils with less than 5% ovality in the pipe ready to install or pipe is supplied in coils or reels which are much smaller than normal coiling processes can achieve. Portable extrusion line and methods of transporting large coils safely and efficiently. Portable extrusion line operates from a series of 40ft containers, the extrusion line is specially designed to operate from inside the containers with many power saving efficiencies such as heat scavenging for material drying and water chilling and electrical power may be from generators capable of being powered by raw gas. From this we provide very long lengths of HDPE pressure pipes e.g. 800m reels of DN315 or 4000m reels of DN160 pipes. Reels only travel locally from portable plant so limited highway disruption. Installation cost of pipe can be hugely reduced in reduction of butt welds. This also improves the pipeline integrity by removing 90 percent of the butt welds. System uses are for major pipe installations such as Shale Gas & Coal Seam Gas gathering lines and water feed lines. Health and Safety of whole pipe installation is also improved by removal of 80% of manual on-site labour. With a combination use of newly developed Coiling Machinery, Portable Extrusion plant and newly developed transportation we here show pipeline installation costs and pipeline maintenance can be greatly reduced.
