Residual stresses created from welding have a direct influence on fracture mechanisms of cracks and flaws in around welded regions. Excessive residual stress can lead to unexpected failures an important property fitness-for-service calculations. In this work, experimental database the low heat input austenitic girth welds is analysed for statistical correlation. The combined measurement profile...

The fatigue life of tubular joints commonly found in offshore industry is not only dependent on the value of hot-spot stress (HSS), but is also significantly influenced by the through-thethickness stress distribution characterized by the degree of bending (DoB). The determination of DoB values in a tubular joint is essential for improving the accuracy of fatigue life estimation using the stress...

To maximise economies of scale future CO2 transport infrastructure, new pipelines within the carbon capture utilisation and storage (CCUS) value chain, should ideally have excess capacity to satisfy transportation demand. However, in scenarios where booster compressors cannot be employed along pipeline, rise pipeline mass flow rate over time culminates higher energy consumption upstream compres...

Abstract There are a lot of welded joints in the shale gas collection pipeline, so failure risk production line is very high. A leak has occurred pipeline dewatering station, and order to find out causes provide technical support for safe transmission, macroscopic analysis, non-destructive testing (X-ray flaw detection), mechanical properties, metallurgical analysis were performed on failed pip...
