Gazprom and ChelPipe, have signed a roadmap for the development and batch production of pipes for offshore projects.
In accordance with the document, ChelPipe will adopt the technology to produce pipes from the 25Cr super duplex steel and the UNS N06625 nickel alloy. Due to these materials, the equipment used in offshore environments will acquire such characteristics as ultra-high strength and corrosion resistance. No pipes of this kind are produced in Russia at the moment.
It is planned to deliver, test and certify prototypes under Gazprom’s requirements in the course of 2018. The pipes will be used in the manufacturing of domestic equipment for subsea production systems, including manifolds and X-mas trees.
