Proven performance for sanitary pressure pipes

Patented bi-stable reel composite tube for pipeline applications

RolaTube Technology, UK, has introduced a globally patented bi-stable reel composite (BRC) that can be repeatedly rolled and unrolled from flat spool to rigid tube. In principle, bi-stable composite reel products are fully capable of replacing and/or reinforcing all retractable and fixed tubular structures such as masts, poles and pipes, resulting in unlimited potential applications. The company has also identified the commercial potential of thermoplastic elastomers (TPEs), high tech plastics that contain rubber-like properties. RolaTube was provided with invaluable research support from the London Manufacturing Advisory Service (MAS), a DTI initiative supported by the London Development Agency.

Sabic Europe, Netherlands, is a supplier of pipe grades in bimodal HDPE and various PP grades. The company’s Vestolen P 9421 is a PP Random copolymer (PPR) grade used in applications such as hot and cold water supply. Pressure pipes made of this grade have been in use for over 30 years, which is longer than any other PPR pipe grade. Vestolen P 9421 is available in a variety of colours and contains a fine tuned stabilisation package proven to be fully effective against thermo-oxidative degradation. Pipes produced from the grade meet the requirements of the commonly used ISO EN 15874 and ISO 3213 standards. Vestolen P 9421 is easy to handle and process on conventional extruders and injection moulding machines, and easy to install. It is also environmentally friendly and corrosion-free. Loose aluminium flanges for PE/PVC plastic pipes Fonderia Fazzini Srl, Italy, produces loose aluminium flanges for PE and PVC plastic pipes, branded FF-PL and FF-PV. Loose aluminium flanges are an alternative to those made from other materials as they benefit from aluminium characteristics including light, hard, corrosion resistance, and cost efficiency. The inside diameter of these flanges is qualified for plastic pipes according to UNI-DIN standard. The mating dimensions are in accordance with the EN 1092-1 PN10/16 standard. The aluminium flanges can be supplied blank, sand-blasted or coated, and are manufactured from EN AC-47000 aluminium alloy. Sabic Europe – Netherlands www.sabic-europe.com

RolaTube can be used for pipelines and pipeline rehabilitation. The company has manufactured and successfully tested prototype designs of flat-reeled composite pressure pipes and linings for the oil and gas industry. The commercial product, when shipped as a reel, and deployed, welded and installed on site, can potentially save up to 90% of transportation costs compared with extruded pipes.

Bistable pipelines are equally useful in replacing and repairing low-pressure aqueous and non-aqueous applications.
