Severstal Steel Pipes for Sakhalin-Khabarovsk-Vladivostok System
Russian steel maker PJSC Severstal has shipped large diameter pipes with unique properties to expand the Sakhalin-Khabarovsk-Vladivostok gas transmission system. LDP with a diameter of 1220 mm and a wall thickness of 36 mm made of steel of strength category X60 were produced at Severstal Russian Steel division’s Izhora Pipe Plant. The strip for the production of LDP was produced at Mill-5000 of the sheet rolling shop located at the same production site with the ITZ.
The production technology provided high plasticity and cold resistance of the supplied pipes without compromising their strength characteristics. This will make it possible to use LDP in the sections of the linear part of the Sakhalin - Khabarovsk - Vladivostok gas pipeline, which pass in zones with difficult seismic conditions.
The Sakhalin - Khabarovsk - Vladivostok Gas Transmission System is the first interregional gas transmission system in the East of Russia. It is designed to deliver gas produced on the Sakhalin shelf to consumers in the Khabarovsk and Primorsk Territories. The GTS route passes through areas with difficult seismotectonic conditions and, in addition to the Nevelskoy Strait, crosses more than 400 water barriers related to the Amur and Ussuri river basins. The length of the route is over 1800 km.
