Laser surface melting (LSM) has the potential to increase the resistance of steels to erosion–corrosion. In this study a submerged jet impingement system containing a brine under saturated CO2 conditions with sand has been used to assess the effect of LSM on the erosion–corrosion resistance of X65 steel. Erosion–corrosion rates under different experimental conditions were deduced based on CFD-simulated...
The interaction between corrosion and erosion has often been a subject of debate among scientists and engineers. The total material degradation when corrosion and erosion interact is often more than the individual components acting separately. Much effort has been directed towards the study of erosion–corrosion behaviour of carbon steels, standard austenitic and duplex stainless steels, highly alloyed...
Various carbon steel sections of pipework removed from an offshore facility were examined and found to have experienced exceptionally high wall thickness losses as a result of internal degradation. This prompted a case study to determine the mechanisms of degradation which had occurred and to ascertain the reasons why the implementation of corrosion inhibitor provided little protection to certain...
Erosion–corrosion of pipeline steel API-5L-X65 has in recent years become an important issue due to the high sand production rate and watercut in the maturing assets. The scope of using corrosion inhibitor to mitigate erosion–corrosion arises due to a number of industrial demands. The present study has been conducted to assess the performance of API-5L-X65 and the effect of corrosion inhibitor under...
A systematic study of pipeline steel (API X65) degradation due to erosion–corrosion containing sand in a CO 2 saturated environment has been carried out. This work focuses on the total material loss, corrosion, erosion and their interactions (synergy) as a function of environmental parameters (temperature, flow velocity and sand content) to enable the critical conditions, which move the damage...
