Pitting Resistance Equivalent Number (PREN): How to Compare Duplex & Super Duplex Alloys
When choosing stainless steel for oil and gas, marine, desalination, chemical processing, mining, and offshore applications, pitting corrosion is one of the most significant corrosion problems. The integrity of pipes, fittings, flanges, valves, and other pressure-carrying components may eventually be compromised by localized, hard-to-detect attacks caused by surroundings containing chloride. The Pitting Resistance Equivalent Number […]
Why Duplex 2205 (S31803) Is the Default Choice for Oil & Gas Pipelines in Africa
Some of the most challenging pipeline conditions in the world are found in Africa’s oil and gas sector. Chlorides, seawater, hydrogen sulfide, carbon dioxide, generated water, high pressure, and temperature fluctuations can all be present in production and transportation systems. Therefore, selecting the appropriate piping material is crucial for preserving pipeline integrity and reducing lifecycle […]
