Piping
Built-up backpressure at the outlet flange of a pressure relief valve
Even for pressure relief valves (PRVs) discharging directly to the atmosphere through short tailpipes, API 520 Part 11 warns that choked flow may develop at the outlet flange, resulting in high backpressure.
Building blocks of process safety
Major incidents continue to strike the oil and gas industry at regular intervals.
Ensure a truly rigorous relief valve sizing method
Pressure relief valves (PRVs) protect equipment from excessive overpressure and, in case of emergency situations, they should ensure a sufficient discharge of mass to reduce the pressure below the recommended pressure limits.
Simplification reduces risks and cuts costs
A facility’s ability to operate safely is the determining factor in its success or failure.
How pipeline management becomes part of a plant safety strategy
A typical refinery or chemical plant contains miles of pipelines.
Optimize your insulation to reduce costs
Corrosion under insulation (CUI) is a common problem that is shared by the oil and gas (onshore and offshore), refining, petrochemical, power and manufacturing industries.
Reliability: Consider stainless steel tubing for mechanical seal connections
If, in days past, you have questioned why hard piping was used for mechanical seal flush lines and seal support configurations in process pumps, you are certainly not alone.
Evaluate structural stiffness for piping stress analysis
Hydrocarbon plants use a system of pipes of various sizes, pressures and temperatures. Sometimes these pipes have pulsating flows that result in piping system vibration. These piping systems must be designed for a high degree of reliability, which requires a comprehensive piping stress analysis for thermal, sustained, occasional and dynamic loading conditions.
Ineos sees Forties oil flows back to normal around new year
LONDON (Reuters) — Britain's biggest and most important oil and gas pipeline Forties should resume normal flows around the new year, slightly earlier than previously flagged, its operator Ineos said on Thursday.
TransCanada clashes with pipeline opponents at Nebraska hearing
LINCOLN, Nebraska (Reuters) — Opponents of TransCanada Corp's proposed Keystone XL oil pipeline argued on Tuesday that regulators in Nebraska had no authority to approve the line's "alternative" path through the state and that the project should be considered dead.
