Piping
High-frequency acoustic excitation—Part 2
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.
Strategies to minimize piping thermal maintenance system cost without compromising performance
Where process fluid must be maintained within a certain operating temperature window, the piping will likely require the application of a thermal maintenance system.
Double-suction centrifugal compressor in ethylene plant inlet piping design
Centrifugal compressors are designed with different suction nozzle orientations and impeller layouts in casing.
Corrosion: Address damage caused by galvanic corrosion
At petrochemical and refining facilities, it is common for U-clamps over piping runs to become corroded, sometimes to the extent where they are completely thinned out.

Stress qualifications for standard and nonstandard valves in piping systems
Various types of valves are used in refineries, petrochemical plants, fertilizer plants and utilities.
Engineering Case Histories: Case 110: A checklist for vibration analysis
Periodically, I receive questions from engineers around the world on why a piece of critical machinery is vibrating excessively.
Safety: Addressing corrosion at petrochemical plants starts with carbon
Maintaining the structural integrity of a pipeline is a significant investment of time and resources for organizations in the oil and gas industry.
Mitigate transient/hydraulic surge in liquid pipelines with nozzle check valves
Liquid pipelines often come across hydraulic transients, which can damage pipelines and associated equipment (i.e., pumps, valves, stations, etc.).
Supply Chain: How to reduce piping inventory
Piping represents a significant part of the plant cost, ranging from 15%–25%.1 Materials stored in warehouses or storage facilities cost companies in terms of personnel, materials, time, space, insurance, risk, etc. This article proposes cost-saving strategies for inventory reduction. Further, it emphasizes consistent naming conventions to avoid creating duplicate/redundant items.
