Kingfisher’s K-Pipe WRP is a polymer- lined high-density polyethylene (PE-HD) abrasion-resistant piping system that is suitable for movement of liquids, sludge and slurry containing abrasive media and contaminants. K-Pipe WRP is used within a variety of industrial sectors for the hydraulic and pneumatic conveyance of materials and offers an inner wear-resistant polymer within its matrix that enhances the service life of the pipe when exposed to abrasive media. It is manufactured via an automated extrusion process that incorporates a traditional HDPE outer sleeve and fuses an inner wear resistant polymer sleeve utilising a patented technology that eliminates the potential for delimitation in service. This results in a system being less expensive than the traditional range of metallics and ceramics used for handling abrasive materials such as ash, coal, minerals and other highly abrasive materials. Typical site uses include ash and dust handling, sewerage processing, tailing pipes, pulp and paper production, along with mining and quarrying applications.

The K-Pipe WRP system allows extra thicknesses of the wear resistant inner polymer to be incorporated, which in areas such as bends and branches where the abrasive effects of the media are most significant results in improved service and performance. Another advantage of K-Pipe WRP is that the system can be joined using a specially developed butt-fusion technology and electro fusion couplings, which results in welded joints as strong and as smooth as the pipe itself. Alternatively, flanges and mechanical sealing joints can be used in the same fashion as steel pipes. Dependant on the inner bore size, which ranges from 63 to 800mm, pipes can be supplied in lengths up to 500m, which reduces the number of joints and reduces installation time. The physical flexibility of the outer HDPE outer surface is an asset in many cases as it is able to absorb stresses caused by soil or ground movement, both

K-Pipe WRP abrasion resistant lining layer is selected for the medium being transported. After an assessment has been made of the composition of the medium and the operating conditions, the most appropriate liner material can be selected from a range of high resistance polymers. Kingfisher works directly with each user to calculate the pipeline’s design life, which determines the thickness of the abrasion resistant layer. This allows an optimum solution that combines high resistance towards abrasion and chemicals with lightweight yet Offering package, a turnkey
