Ukraine's largest vertically-integrated mining and steel group Metinvest has reported that its subsidiary Ukrainian pipe producer Khartsyzsk Pipe Works (KhPW) has manufactured over one million mt of large diameter pipes for the construction of the Central Asia-China gas pipeline.
KhPW is a supplier of large diameter pipes for all participants in the transnational Central Asia-China gas pipeline project. Over one million pipes have been shipped for the Uzbekistan-China and Kazakhstan-China sections and for the Beineu Bozoi-Shymkent gas pipeline.
KhPW's pipes will also be used for the construction of the 'C' branch of the Central Asia-China gas pipeline. This branch goes over the territory of Uzbekistan, Kazakhstan and Turkmenistan, and is designed to increase the transit of gas from Central Asia to China. It extends for 1,840 km. The design capacity of the 'C' branch will be 25 billion m3 of gas per year. It is scheduled to be commissioned in 2014.
For construction of the 'C' branch, KhPW supplied single-seam 1,219 mm diameter pipes from high strength X80 grade steel with external anti-corrosion and internal epoxy coatings. The pipes were manufactured according to customer technical requirements based on international standards API Spec 5L (level PSL 2), CSA Z 245.21 and API RP 5L2.
