Linepipe plates

Specializing in extreme conditions

Lowest arctic temperatures, highest pressure in the deep sea, acidic media: Even the most adverse conditions cannot harm our linepipe plates. Our plates can be found at depths of up to 3000 meters below sea level as sourgas-resistant linepipe plates or as land pipelines with a diameter of up to 48" (1220 mm). The highest sourgas requirements are met by our roll-bonded linepipe plates with corrosion-resistant cladding. As specialists in modern thermomechanical rolling processes with accelerated cooling, we are one of the world market leaders in linepipe plates. More than 2 million tons of sourgas-resistant linepipe plates and extremely tough linepipe plates for thick-walled deep-sea pipelines are ample proof of our product success.
