UK valve supplier Orseal are further extending their reach into the Indian steel market, with two high-profile oxygen service valve contracts. Orseal are currently delivering oxygen service valves to Nagarnar. They are also fulfilling a contract for one of the largest EPC contractors in India as part of the upgrade of SAIL’s BF-1 at Rourkela Steel Plant.
The Nagarnar integrated steel plant of state-owned iron ore mining company NMDC is due for completion in December 2017, and Orseal valves are currently being delivered to the plant in India. Once commissioned, the plant’s blast furnace for manufacturing steel could emerge as one of India’s largest, with the 3 MT annual capacity likely to reach 50% production in the first year.
For the Nagarnar plant, Orseal’s Special Projects Division, which undertakes customised valve design and manufacture including valve packages, supplied from ¾” to 18” FB flanged valves in brass with Monel trim. These were trunnion mounted for 18” and floating for 6” and under, suitable for operating temperatures of up to 60oC. Brass, which has under 2.5% aluminium content. Before dispatch, Orseal subjected the valves to a process of ultra-cleaning to remove all grease that might react with oxygen.
