Abstract
Material and corrosion assessment are crucial engineering tasks that can deeply influence the satisfactory performance of interfield and export lines over the design lifespan. The project conditions to be pursued, can be different, and the field of engineering investigations needed and technical solutions developed, vast. The selection of line pipe material at design stage, in relation to the transported products and flow rate, relevant temperature and pressure profiles along the route and external environment as well, is a factor for a successful project. To be noticed that there are significant differences in the relevant engineering tests for the final selection, whether dealing with a short small diameter multi-phase flow line or a long strategic large diameter treated gas trunk line. On the other hand, the integrity management of a line over the operating time span, when the variation of transported product composition or inlet temperature and pressure as well, may occur, is a very specific process, to be assessed case by case, far different from the management of a strategic gas trunk line the performance of which over time is not subject to significant variation of transport conditions and the integrity of which may affect the vital activities of a district. In most circumstances the relevant project decisions regarding material and corrosion management are to be taken at a very early design stage, deeply influencing the future project development and operation as well. It shall be a very expert and safe decision. In this paper we will provide a brief overview of a few topics regarding strategic pipeline material selection and integrity management of interfield network, referring to recent outstanding R&D and project experiences.
