Summary of Project

“The use of thermoplastics pipes systems for gas distribution has been a big success. These materials and polyethylene in particular have become the first choice for low pressure gas systems up to 10 bar, solving the corrosion and reliability issues of steel and ductile iron systems. However it is unlikely that any significant increase in pressure rating can be obtained by future material development alone. Development is now concentrated on multilayer and composite pipe constructions to satisfy specific application requirements and to increase pressure ratings respectively…There has been a lot of interest in multilayer pipe in the plastics pipes industry in recent years. This has resulted in the development and publication of standards for both indoor and outdoor gas applications utilising such products, ISO 17484 and ISO 18225 respectively, see Appendix 1. Co-extrusion of pipes with metal or different polymer layers is a highly developed process and a method of obtaining pipe with specific material properties on the bore or external layer.” “Reinforced thermoplastic pipes (RTPs) are considered as prospective alternatives to traditional steel pipes in various offshore oil and gas applications due to their attractive properties such as better corrosion resistance, high stiffness and strength to weight ratios and low maintenance costs. However, as RTPs are relatively new products, their design and qualifications are governed by industry practice at present, which only cover limited loading cases. More advanced analysis is required to investigate the mechanical response of RTPs in detail when they are subjected to loads and combinations of loads typical for offshore pipes.” It is proposed that a combination of materials and forming techniques be developed to produce a pipeline product that can outperform current pipeline technology. A survey of current technology would be conducted with prototypes designed and tested.
