Increased Strength

Specimens of pipe steel of increased strength grade type K56-K60, with different values of impact toughness (KCV) were investigated: a metallographic examination of the specimens’ structure was carried out by optical and electron scanning microscopy methods. The interrelation of the microstructure with mechanical properties, in particular with impact toughness and their influence on the nature of fracture pattern is established.

There are several methods currently being used to install offshore oil and gas pipelines. The reel-lay process is fast and one of the most effective offshore pipeline installation methods for seamless, ERW, and UOE line pipes with outside diameters of 18 inches or less. In the case of the reel-laying method, line pipes are subjected to plastic deformation multiplication during reel-laying. It is thus important to understand the change of the mechanical properties of line pipes before and after reel-laying. Therefore, full-scale reeling (FSR) simulations and small-scale reeling (SSR) simulations are applied as evaluation tests for reel-laying. In this study, FSR simulations were performed to investigate the effect of cyclic deformation on the mechanical properties of weldable 13Cr seamless line pipes. Furthermore, SSR simulations were performed to compare the results obtained by FSR simulations.
