The corrosion pits confirmed this and also the way in which the corrosion in the pipeline accelerated over time was characteristic of the way in which microbiological corrosion develops, as the bacteria grow and multiply.The bacteria forms in water, so that problems associated with microbiological corrosion were suspected to be associated with
(PDF) PIPELINE CORROSION CONTROL IN OIL AND GAS Corrosion in pipelines is one of the major challenges faced by oil and gas industries all over the world. This has made corrosion control or management a major factor to consider before setting up
Case Studies Inspectioneering contributors and authors have published numerous mechanical integrity case studies in Inspectioneering Journal and throughout our online resources. This page brings all of these case studies into one location to better help you learn from the experience of others.
Case Studies Of Corrosion Failures In Oil Refineries Mar 14, 2010 · This paper describes three corrosion case histories caused by overconfidence and lack of thorough understanding of the corroding systems. The first case history is exchanger tube failure from excessive high temperature sulfidation caused by changes of operation condition, run
Case Study:CH-1960 REFINERY REDUCES OVERHEAD Case Study:Refining Process Treatment REFINERY REDUCES OVERHEAD CORROSION THROUGH CONTINUOUS ANALYSIS AND ONLINE CONTROL INTRODUCTION Corrosion of crude unit overhead exchangers continues to be a significant integrity and reliability concern within the refining industry. For many crude units, good desalting and caustic injection practices are the

Corrosion Management in Gas Treating Plants (GTPs A Case Study in Sour Gas Refinery R.Mesgarian National Iranian Gas Company (NIGC) Many of the causes of amine plant corrosion corrosion in amine pipe lines and equipments can be divided in two areas (high corrosion zone and low corrosion zone) for DEA solution. High corrosion
Failures in Coke Drum Overhead Piping Delayed Coker UnitKochi Refinery 1 ½ inch MP steam purge line to coke drum overhead relief valve line was found failed due to weld crack in half coupling . Vibration was noticed in small bore piping. Flexible braided steam hose connected to the 1 ½ inch MP steam line was found damaged and broken Failure Case-3
Drill pipe is one kind of important tools for drilling in oil field. Drill pipes are subjected to various types of loads and are operated under different environmental conditions. Incidents of drill pipe failure due to fatigue, corrosion (local, i.e., pitting and groove), and stress corrosion are very common in the field.
