Duplex Steel Tubing finds extensive use in applications requiring higher corrosion resistance and mechanical strength. Within the oil and gas sector, it is applied in subsea pipelines, risers, and wellhead parts owing to its ability to resist chloride-induced stress corrosion. Within chemical processing, it finds application within heat exchangers, pressure vessels, and reactors involving acidic or caustic media. It is employed by the marine industry for desalination plants, offshore units, and ship parts. It is used in paper and pulp mills, structural frames, and water treatment systems where durability and resistance against aggressive chemicals are called for.
