Integrity management of pipeline is vital for sustainable production. Among all of pipeline
failure threats, contribution of corrosion is significant and has been reported up to 50%. This …

Owing to the findings of new locations for crude oil and natural gas, the need of high
strength materials that can be used for pipes and their joining has gained paramount …

This study examines the influence of arc pulsation and ErNiCrMo-3 filler metal on stress
corrosion cracking (SCC) in P91 steel weld joints using activated tungsten inert gas (A-TIG) …

In this study, the effects of hydrogen on the fracture toughness and crack propagation of X80
steel base metal and girth weld were assessed. The crack tip opening displacement (CTOD) …

This paper investigates the effects of ERNiCr-3 butter layer on the microstructure and
mechanical properties of API 5 L X65/AISI 304 dissimilar joint, welded by gas tungsten arc …

High strength steel, as API 5L grade X80 and above, have been applied in pipelines for sour
service in oil and gas industry. Hence, comes the concern about the risks comprising …

Natural-gas pipelines converted to carry hydrogen could have reduced mechanical
properties due to hydrogen embrittlement. The tensile properties of the X65 D pipeline steel …

The aim of this research was to evaluate the influence of microstructure on hydrogen
permeation of weld and API X52 base metal under cathodic protection. The microstructures …

Dissimilar metal welds (DMWs) are routinely used in the oil and gas industries for structural
joining of high strength steels in order to eliminate the need for post weld heat treatment …
