Onshore large-diameter pipes LSAW

Large diameter pipes are used for construction of oil and gas pipelines.

For its clients, Severstal through the production asset Izhora Pipe Mill with more than 15-year experience and a production capacity of about 600 thousands of tonnes per year provides longitudinal seam (LSAW) pipes in accordance with the international standards. Pipes are manufactured from 508 to 1422 mm in diameter, with steel grades reaching up to X100, and lengths from 12 to 18.3 m.

Pipes of 18.3 m in length enable to decrease the cost of pipelines construction, as less amount of welding points become necessary.

When it comes to meeting specific needs of our customers, thanks to the full control over the entire manufacturing process (from slabs to pipes) and with the advanced R&D center we offer customized solutions on time and the ability to develop new products for technically challenging projects.
