Corrosion under insulation (CUI) is a severe form of localized external corrosion that occurs on stainless steel (SS) that has been insulated.
Large-diameter piping used in the petrochemical, oil and gas, steel plant and power industries often carry toxic fluids and can pose significant safety hazards.
The fluid catalytic cracking unit (FCCU) is the primary conversion equipment for modern refineries to obtain clean transportation fuels, along with high-grade petrochemical feedstock.
Stainless steel is a generic term used for a large group of corrosion-resistant alloys containing at least 10.5% chromium (Cr), and possibly containing other alloying elements like nickel (Ni), molybdenum (Mo), manganese (Mn) and nitrogen (N).
Bazan Group’s crude unit No. 3—not designed by any of the authors’ companies—was bottlenecked by the preflash tower.
A process safety risk in industry is having unknown problems that are not accounted for.
The carbon dioxide compressor is one of the key major equipment in a urea production plant that produces fertilizers.
Job requirements and scope are well defined in engineering, procurement and construction (EPC) contracts because they are designed and engineered from scratch.
Failure of a piping section at the outlet of pressure safety valves (PSVs) and control valves—where significant differential pressure exists (particularly in gas processing industries)—is a common problem in industries.
Where process fluid must be maintained within a certain operating temperature window, the piping will likely require the application of a thermal maintenance system.
