Gazprom informed that pipe No.1 for the first line of South Stream’s offshore section was produced at the Vyksa Steel Works (part of the United Metallurgical Company – OMK).
Unique pipes for South Stream’s offshore section are 12 meters long, 813 millimeters in diameter and have a wall thickness of 39 millimeters. These pipes made of SAWL 450 steel are designed for the super-high operating pressure of 28.45 MPa.
Since early April, Severstal (Izhora Pipe Mill) and German EUROPIPE have also been preparing for manufacturing these pipes.
The first pipes will be delivered to Bulgarian harbors in early summer, so that the construction of the first line of South Stream’s offshore section will start in autumn 2014.
South Stream is Gazprom’s global infrastructure project aimed at constructing a gas pipeline with a capacity of 63 billion cubic meters across the Black Sea to Southern and Central Europe for the purpose of diversifying the natural gas export routes and eliminating transit risks.
South Stream’s offshore section will consist of four lines, each exceeding 930 kilometers.
Pipe supply contracts for the first line were awarded to EUROPIPE from Germany (50 per cent of the total amount), United Metallurgical Company – OMK (35 per cent) and Severstal (15 per cent) from Russia.
Pipes for the second line will be supplied by Marubeni-Itochu and Sumitomo consortium from Japan (40 per cent of the total amount), OMK (35 per cent) and Severstal (25 per cent).
