... flowlines integrity are complex with no single solution approach to address the myriad of different conditions. This paper present two cases of metallic and non-metallic materials installed in PDO flowlines showing their historical field performance and discusses the strategy adopted for the material...

... properties loss due to creep or thermal effects. Organic non-metallic materials will experience both creep and permanent mechanical properties degradation at much lower temperatures. The extant of chemical degradation of corrosion resistant alloys, except for hydrogen embrittlement, at temperatures below 250...

... reported previously for engineering evaluations of non-metallic materials. This paper first examines how the requirements for using the methods discussed above create certain experimental restrictions. That is, the estimation procedure used affects the ability to estimate the diffusion coefficient...
