As service demands increase, the oil gas, chemical, marine and mining industries require enhanced performance from a wide range of product and process pipework systems. Improved corrosion resistance is needed to withstand combined sour gas/CO2 attack, the conditions in sea water injection lines, and a diverse range of corrosive chemicals and operating environments. Longer service lives may be sought by increasing steel pipe wall thickness to give a corrosion allowance, or by specifying a corrosion resistant alloy grade. In either case, the resulting pipework may be considerably more expensive than an installation in conventional C-Mn steel. A new type of pressure pipework system is proposed. This consists of steel pipe which is lined by a thermoplastic layer, and which can be joined in the shop and in the field by butt welding to give continuous lengths of plastics lined steel pipe. The present paper presents an insight into an ongoing programme which is directed at the development of a new family of thermoplastics lined metal pipes which may be joined by welding. The development programme is focused on applications involving complex runs and high operating pressures, which are not susceptible to alternative multiwall solutions such as dry lining or joining by flanging and mechanical fastening.
