Plast ic pipes

Application of high-pressure pipes HexelOne ® pipes, from German plastic pipe system manufacturer egeplast, can be installed by means of trenchless installation. installation without a sand bed, for ploughing, milling, relining and HDD. The high-pressure polyethylene pipe can withstand pressure up to 32 bar (water) and 16 bar (gas).

load resistant inner layer made from PE 100-RC and an additional protective coating made from abrasion-resistant polypropylene. The pipes are supplied with transparent outer layer, with silver-coloured HexelOne pipe and coloured stripes on the core pipe as media labelling. TÜV certification has been granted. The HexelOne pipes are also available with diffusion barrier layers (SLA ® ), conductive strips for position finding (DCT ® ) and additional layers for leak detection (3L ® ). The transparent coating permits the integration of a readable barcode label.

The high-pressure pipes with protective coating can be used for open trench installation in a sand bed, open

Polymers and pests Polymers and plastics are widely used and form the base of a host of materials. Rodents are attracted by the sweet smell of polymers and consequently rodent damage is one of the most widespread complaints from the pipe industry.

and safety aspects, Rodrepel ® ™ and Termirepel ® ™ were developed by C Tech Corporation. Rodrepel and Termirepel are patented non-toxic, non-hazardous and environmentally friendly aversives specially developed as a master batch for use in polymeric and coating applications. The products are RoHS- and REACH-compliant, and FIFRA exempted. They deter the pests by making use of the sensory mechanisms. They do not interfere with the properties of the polymer and are completely inert within the polymer matrix, apart from acting as an aversive. Rodrepel and Termirepel do not volatilise and are compatible with all kinds of polymers. They have undergone extensive testing at testing institutes like the BAM Institute in Germany and the Haffkine Institute in India.

Gas pipelines, drip irrigation pipelines, and tubing for wires and cables are some of the most-affected by pests. Damage to gas pipelines can have adverse consequences. Damage to drip irrigation pipelines by rodents and subterranean termites not only defeats the purpose of water conservation but it is also expensive to replace the pipe. Damage to the tubing and wiring harness of automobiles by rodents can cause thousands of dollars in losses. Conventional methods of rodent and termite control fall short, as they do not effectively control the pests. Also, being toxic they cannot safely be used in all applications. It is imperative to effectively solve the problem of polymer piping damage by pests and also to provide a long-term solution. With this aim, and keeping in mind environmental
