Linepipe plates

Specialist for extreme conditions

Extremely low arctic temperatures, extreme pressures in the deep ocean, acid media: Even the most difficult conditions have no negative effect on our linepipe plates. Our plates are found in depths of up to 3,000 meters below the sea surface, either in the form of sour-gas-resistant linepipe plates or as land lines up to 48 inches (1,220 mm) in diameter. We also offer roll-bonded clad linepipe plates with a corrosion-resistant cladding for the highest demands in sour-gas application. As a specialist in modern thermomechanical rolling technology with accelerated cooling, we are among the world's industry leaders. More than two million tons of sour-gas-resistant linepipe plates and high-toughness linepipe plates for thick-walled deep-sea lines testify to the success of our high-quality products.
