Bending and buckling of internally-pressurized steel lined pipes
(2019)During offshore installation, steel lined pipes are subjected to severe plastic bending, resulting in detachment of the thin-walled liner pipe from the outer pipe and eventually, the formation of local buckling in the form ... -
Dented externally-pressurised pipes subjected to cyclic axial loading
(2019)The present paper describes a numerical investigation of the mechanical response of externally-pressurized dented stainless-steel pipes, subjected to reverse cyclic axial loading. This is the first part of a large-scale ... -
The effect of spiral cold-bending manufacturing process on pipeline mechanical behavior
(2016)Large-diameter spiral-welded pipes are employed in demanding hydrocarbon pipeline applications, which require an efficient strain-based design framework. In the course of a large European project, numerical simulations on ... -
The effect of spiral cold-bending manufacturing process on pipeline mechanical behavior
(2019)Large-diameter steel pipes, fabricated through the spiral-welding manufacturing process, are extensively used in onshore pipelines for the transmission of energy (hydrocarbon) and water resources. However, their use in ... -
Effects of UOE manufacturing process on pressurized bending response of offshore pipes
(2014)Thick-walled steel pipes manufactured through the UOE process are used in deep-water pipeline applications for the safe and cost-effective transmission of hydrocarbon energy resources. Such pipes are subjected to bending ... -
Finite element analysis of cyclically-loaded steel pipes during deep water reeling installation
