- Reinforced thermoplastic pipe
RTP is a plastic pipe, initially developed by
Akzo Nobel early 90s and by Tubes d'Aquitaine [ [http://www.materials-careers.org.uk/careers/tubes.htm Tubes d'Aquitaine - Inventor of RTPs] ] from France, who developed the first pipes reinforced with synthetic fiber to replace steel high pressure pipes.
Material of the pipe might bePolyethylene (PE),Polyamide -11 orPVDF and can be reinforced withAramid orPolyester fibre. [ [http://www.automateddynamics.com/docs/thermoplastic_composites.pdf Different materials for RTP - CEAC Automated Dynamics] ]
Nowadays the technology of producing such pipe including the marketing is mainly in hands ofPipelife withSoluforce and available in coils up to 400m length. 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.

The pipe mainly benefits applications where steel fails due to corrosion and installation time is an issue.Technology and history
The idea of synthetic fiber reinforced pipe came from Akzo Nobel, where Bert Dalmolen initiated a project to develop such a pipe. He was later hired by
Pipelife where a state of art production line was developed to produce RTP. Pipelife also developed a pipe reinforced with steel wire to achieve even higher pressure ratings of over 150Bar.Mr Chevrier (Tubes d'Aquitaine) also developed machinery that could produce such pipes, but was not successful in commercialising RTP.
