Experimental batches of tubes made of thick sheet strength category to the X100, which have no analogues in Russia, were produced by in 2009 and successfully passed the tests. Manufacturing of the product in commercial quantities will provide the design, construction, and high operational reliability of gas and oil pipelines and welded structures Arctic.
Reference: 5000 produces a wide strip thick sheet for the needs of shipbuilding and nuclear power industry, fuel and energy complex. Stan self-sufficient Strips JSC "Izhora Pipe Plant" (IPM). Key consumers of pipes ITZ produced from strip mill 5000, are JSC "Gazprom", OJSC "AK" Transneft "and other oil and gas companies.
