MATERIALS | PRESSURE PIPES
tures and pressures – challenge the use of steel. The conditions mean that most conventional polymer/composite systems are at the limit of their performance. An approach from Magma and Technip puts a conventional armour and sheath around a TCP to create the HFP. The idea if to extend strength to weight ratio, compared to a conventional flexible pipe. The HFP uses a Peek-based carbon fibre composite that offers high temperature and chemical resistance – including low permeation and a barrier against corrosion.
Exploring plastics Also in the field of oil exploration, the UK-based Non-metallic Innovation Centre (NIC) has joined forces with SoluForce of the Netherlands to carry out research that will expand the capabilities of plastic pipes in service.
R&D activities will focus on increasing the
operating temperature and pressure that rein- forced thermo-plastic (RTP) pipes can withstand when transporting hydrocarbons. The aim is to create a new, more affordable, spoolable compos- ite pipe.
Combining high performance and cost competi- tiveness will help to make non-metallic pipes more prevalent across the oil and gas industry, say the partners. The long-term strategy is to reduce manufacturing costs whilst optimising the cost benefit of developed products. Plastic pipes offers a number of potential benefits over metal pipes, including corrosion resistance to corrosion, light weight, flexibility, durability and reduced carbon footprints. R&D will take place at the NIC’s Cambridge base
– in TWI’s headquarters – and a prototype product will be made by SoluForce. NIC will carry out materials selection processes, investigate the potential use of recently developed and commer- cially available options, and evaluate the new pipe.
