Grooving Corrosion of Electric Resistance Welded Pipe

Heat Transfer Modeling of an Annular On-Line Spray Water Cooling Process for Electric-Resistance-Welded Steel Pipe

On-line spray water cooling (OSWC) of electric-resistance-welded (ERW) steel pipes can replace the conventional off-line heat treatment process and become an important and critical procedure. The OSWC process improves production efficiency, decreases costs, and enhances the mechanical properties of ERW steel pipe, especially the impact properties of the weld joint. In this paper, an annular OSW...

Probabilistic Pitting Corrosion Risk Assessment of Welded Offshore Steel Pipelines

Steel structures continuously exposed to offshore marine environments are prone to corrosion. This can be of major economic and perhaps of environmental significance. The risk of these scenarios occurring can be assessed using good quality data, good quality corrosion and pitting models and structural reliability assessment. Recently, improved models for the prediction of longer term corrosion ...

Fretting Corrosion in Electric Contacts

Fretting corrosion is a form of accelerated atmospheric oxidation which occurs at the interface of contacting materials undergoing slight, cyclic relative motion. In electric contacts involving non-noble metals, fretting action can cause rapid increases in contact resistance, proceeding to virtual open circuits in a matter of minutes in the worst cases. Experimental results of resistance increa...
