Soluforce is an RTP, which is a flexible pipe, supplied in long length coils up to 400m length and pressure ratings from 30 to 90 bar. In the last few years, this type of pipe has been acknowledged as the standardised solution for oilfield flowlines and also recently used offshore for water injection risers and oil flowlines.
A very great advantage of this pipe is also its very fast installation time compared to steel pipe as speeds up to 1000 m/h have been reached installing RTP in ground surface.
The pipe mainly benefits applications where steel fails due to corrosion and installation time is an issue. Beside the application for oil transportation, this pipe is also applied for gas transport lines.
The Soluforce RTP is a three layer pipe construction:
- A HDPE liner pipe
- The reinforcement layer, typically Aramid (Twaron or Kevlar)
- The HDPE protective outer layer for UV, damage and abrasion protection
Soluforce is used for the following applications:
- Oil field flowlines
- Oil field waste water disposal lines
- Oil field injection lines
- Offshore water injection risers
- Offshore oil flowlines
- High pressure Water transportation lines
- High pressure gas transport lines
- Relining existing pipes
