Strain accumulation as a result of cyclic loading affects the microstructure and mechanical
performance of low-alloy steels under cyclic operation conditition. This manuscript presents …

Microstructure of the 40-year service-exposed 1Cr-0.5 Mo steel extracted from pressure
vessels through the boat sampling technique was characterized using x-ray diffraction, field …

Coke drums are critical equipment in the petroleum industry. The failure modes of coke
drums include excessive bulging deformation and fatigue cracking. The elastic-plastic …

Repetitive and severe thermal loads and load changes affect not only the physical
properties of the coke drum but also its dynamic properties, possibly leading to structural …

Coke drums are vertical pressure vessels used in the delayed coking process in petroleum
refineries. They are operated under severe thermal–mechanical conditions by cyclic heating …

Coke drums are vertical pressure vessels used in the delayed coking process in petroleum
refineries. They are normally constructed of carbon or low carbon alloy steels internally clad …

Low-cycle fatigue failure has been widely accepted as the key mechanism causing
damages of coke drums during cyclic thermal-mechanical loadings. Common damages of …

The flow field in a cylindrical container driven by a flat bladed impeller was investigated
using particle image velocimetry (PIV). Three Reynolds numbers (0.02, 8, 108) were …

Thermomechanical fatigue tests are performed on SA387Gr11CL2 (1.25 Cr-0.5 Mo) low
alloy steel, which is widely used in the manufacture of coke drum. Thermomechanical …

Coke drums undergo cyclic thermal and mechanical loading during operation, which tend to
cause damage like bulging and cracking near circumferential welds in coke drums. In this …
