The trunk pipeline transport of oil and gas is the crucial part of Russian economy and the focus of the latest achievements of domestic and foreign science and technology. In 2008, the length of Russian trunk pipelines exceeds 223 thousand km, of which 160 thousand km of gas-pipelines and 63 thousand km of oil-pipelines. The pipeline transport was pumped more than 488 mln tonnes of oil and oil products and 565 million tons of gas. The freight turnover of pipeline transport amounted to 1.156 trillion tonne-km of oil and oil products and 1.317 trillion tonne-km of gas. To ensure the high requirements to the trunk pipeline exploitation, the forming process of pipe billet according to the scheme JCOE is established on the market of production of welded large-diameter pipes. In this paper, the mathematical model for the calculation of the steel billet’ form after the O-forming press is obtained. At a forming process the elastoplastic medium model of steel is used. The research results mean for the calculation of the press’s optimal calibration in the production of the thick-walled straight-line-single-seam large-diameter welded steel pipes according to the scheme JCOE for main gas and oil pipelines.
