Abstract

This study examines the effect of hydrostatic pressure testing on the microstructure of a carbon steel pipeline material. The study is targeted at establishing the likelihood of change in the microstructure of the tested pipe material. The experimental assessment involves subjecting two spools to service and hydrostatic pressures respectively, cutting the spools and preparing samples for metallography and finally, comparison of the photomicrographs and metallographic results to that of a control pipe spool. The results obtained showed that there is a significant change in the grains arrangement in both the service and hydrostatic pressure tested cases but more pronounced in the microstructure of the hydrostatically tested specimen.
