Pitting Resistance Equivalent Number (PREN): How to Compare Duplex & Super Duplex Alloys

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 […]

Duplex Steel for Mining Applications: Grades, Advantages & Supplier Selection Guide

Duplex Steel for Mining Applications: Grades, Advantages & Supplier Selection Guide

Piping and equipment are subjected to some of the harshest industrial environments during mining operations. Rapid corrosion and wear can be caused by slurries that comprise chemicals, dissolved minerals, chlorides, acidic process water, and abrasive particles. However, material durability is crucial since mining systems frequently work under high pressure and continuous production circumstances. Due to […]

Why Duplex 2205 (S31803) Is the Default Choice for Oil & Gas Pipelines in Africa

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 […]
