Many methods have been proposed for leak detection in pipelines. The method based on the acoustic signals created by the leakage is a non-destructive method and has presented reliable results. However, applying such a method in noisy environments is…

Pipeline transportation is the most economic and reasonable transport means of petroleum and natural gas. Influenced by complex corrosion environment, it is challenging to detect anomalies accurately with precise boundaries. Inspired by the idea of…
Chemical, petrochemical, and refinery sectors have been facing tougher safety, environmental and mechanical integrity regulations as well as challenges associated with the need for cost reduction to improve competitiveness. Risk-based Inspection…
The coulometric method of measuring humidity and oxygen on the basis of an electrolytic cell with a film of phosphorus oxide for continuous analysis of natural gas in pipelines of its transportation is considered. On the basis of the method the…
This paper proposes a microwave non-destructive testing (NDT) method to detect and estimate the volume fraction of fresh or saline water in natural gas pipelines. The gas pipe is modelled as a waveguide that is filled with gas and different…
During plant shutdown maintenance, some components cannot be removed out of service immediately for metallurgical examination due to high cost involved and loss of production hours. The best alternative is to replicate the lab based metallography…
