Krupp Precision Tubing, a renowned German materials enterprise, has announced the large-scale mass production of its independently developed third-generation super duplex stainless steel pipes. Designed for high-salt and high-corrosion marine environments, this product will significantly reduce the pipeline maintenance costs of offshore wind power, deep-sea oil and gas development, and other projects. Moreover, its related technologies have passed the EU marine engineering material certification.
The new stainless steel pipe employs “nickel-molybdenum alloy composite strengthening” technology. While retaining the high-strength characteristics of traditional stainless steel, it has improved chloride ion corrosion resistance by 40% and extended the service life from 15 years of traditional products to more than 25 years.
The company plans to apply the new pipelines to the expansion project of the Juno oil field in the North Sea, and the first batch of pipeline laying is expected to be completed in Q2 of next year.
