Crack growth behavior of X65 pipeline steel at free corrosion potential in near-neutral pH soil environment under a CO2 concentration gradient inside a disbonded coating was studied. Growth rates were found to be highest at the open mouth of the simu

This investigation enabled the identification of a discontinuous crack growth mechanism of pipeline steels in near-neutral pH environments, which was determined from experimental simulations lasting more than 4 months, using a novel experimental setu

In order to maintain pipeline operation during repair and maintenance work, operators typically install branch (i.e. hot-tap) and repair fittings (i.e. sleeves) onto flowing pipelines. In-service welding procedures must be designed for these installa

The susceptibility of pre-weld heat treated laser beam welded IN 738 superalloy to heat affected zone (HAZ) cracking was studied. A pre-weld heat treatment that produced the minimal grain boundary liquation resulted in a higher level of cracking comp

Microstructural study of laser-beam-welded IN 738 superalloy was carefully performed to better understand the causes of heat-affected zone (HAZ) cracking and to determine an improved approach of alleviating the weldability problem. The HAZ cracks in

Near-neutral pH stress corrosion cracking (NNPHSCC), which occurs when ground water penetrates under the pipe coating, causes longitudinal cracks to develop on the surface of pipelines. Such cracks grow over time and can ultimately lead to pipeline f
