[edit] RTP - Reinforced Thermoplastic pipe
This type of plastic pipe is initially developed by Wavin early 90s and by Tubes d'Aquitaine[1] from France, who developed the first pipes reinforced with synthetic fiber.
Material of the pipe might be Polyethylene (PE), Polyamide-11 or PVDF and can be reinforced with Aramid or Polyester fibre[2].
Nowadays the technology of producing such pipe including the marketing is mainly in hands of Pipelife with Soluforce and available in coils up to 400m lenght. These pipes are available in pressure ratings from 30 to 90Bar. The last few years this type of pipe is acknowledged as the standardised solution for oilfield flowlines[3]. A very great advantage of this pipe is also its very fast installation time compared to steel pipe as speeds up to 1000m/hr have been reached installing RTP in ground surface[4].
The pipe mainly benefits applications where steel fails due to corrosion and installation time is an issue.
[edit] Technology
Mr Chevrier, also founder of Tubes d'Aquitaine developed machinery that could produce such pipes. This technology has been sold and is now marketed by Krauss-Maffei[5], who recently sold a RTP production line to a Chinese client[6].
