Pipeline manufacturers talk South Stream at Gazprom HQ

January 24, 2013 - The Gazprom headquarters hosted a regular meeting of Alexey Miller, Chairman of the Company's Management Committee and heads of Russian pipe manufacturing companies (*).

Gazprom has a long history of successful cooperation with Russian pipe manufacturers, including interaction in innovative products development. The unique large diameter pipes specially developed for the construction of the Bovanenkovo – Ukhta, a new generation gas trunkline system, may serve as an outstanding example of such cooperation. These 1,420 millimeter high-strength cold-resistant flow-coated pipes made of K65 (X80) steel are designed for the operating pressure of 11.8 MPa – the world's record for onshore gas pipelines.

“Gazprom has new gas transmission megaprojects ahead – South Stream and Power of Siberia. We place higher demands on the pipes that will be used for the construction of these gas pipelines. For instance, the Power of Siberia gas trunkline system will be laid through a territory of high seismic activity. We need pipes that will secure reliable gas transmission in such complicated conditions.

For the first time in the global history of offshore gas pipelines construction, the pipes with a 39 millimeter wall thickness designed for the operating pressure of 27.73 MPa will be used while implementing the South Stream project. Moreover, it will be the first time when 813 millimeter pipes will be laid as deep as 2,250 meters. I invite you to take part in these projects, but once again I remind you that they should be implemented in line with the highest global standards,” said Alexey Miller.

The meeting participants discussed the test results of experimental large diameter pipe (LDP) batches designed for the construction of the South Stream offshore section. The pipe test results and production specifications were verified by DNV certification body that confirmed the possibility of their production and application during the construction of the South Stream offshore section.
