medium and the operating conditions, the most appropriate liner material can be selected from a range of high- resistance polymers. Offering a turnkey package, Kingfisher works directly with each user to calculate the pipeline’s design life, which deter- mines the thickness of the abrasion- resistant layer. This allows an optimum solution that combines high resistance towards abrasion and chemicals with lightweight yet durable pipework that is quick and easy to install. 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.

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. K-Pipe WRP’s abrasion-resistant lining layer is selected for the medium being transported. After an assessment has been made of the composition of the

fashion as steel pipes. Dependent 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 HDPE outer surface is an asset in many cases as it is able to absorb stresses caused by soil or ground movement, both the minor movements of settling and more major movements, for example in earthquake-prone areas. Being a plastic, there is no need to paint or coat it to protect it from most corrosive environments.

of line pipe coating,” said Cedric Oudinot, global product line manager at Bredero Shaw. “It offers significant benefits for operators – and it’s competitively priced, so they get a superior solution without having to pay more.” Bredero Shaw, a division of ShawCor, provides specialised coating systems and related services for corrosion protection, insulation and weight coating applications on land and marine pipelines, including highly engineered corrosion and insulation systems for deepwater applications.

Formulated with a proprietary molecular structure, SureBond is claimed to provide better pipe protection and superior bonding with all field joints.

Bredero Shaw’s SureBond™ onshore pipe coating was developed to match or exceed the performance of three-layer coating products.

It eliminates the often- problematic adhesive layer, while providing strong, virtually permanent protection of the anti-corrosion layer. The SureBond product line performs across a wide temperature range, from -70°C to 100°C, with low temperature bending and thermal cycling performance, a known limitation of three- layer systems.
