Orseal has provided valves for highly demanding applications including high temperatures and processes with high corrosion-resistance.
Oxygen service has many inherent dangers. All materials will react with gaseous or liquid oxygen at certain temperatures and pressures. The reaction may cause a fire or an explosion, which makes it vital for valve suppliers to the steel industry to have a thorough understanding of system processes and material properties. The selection of the wrong valve material could have disastrous consequences.
One of Orseal’s most recent oxygen-service projects was for ISP in West Bengal, a fully-integrated iron and steel plant that was undergoing a modernisation programme to increase its capacity to 2.5 MT per year.
Orseal’s Special Projects Division, which undertakes customised valve design and manufacture including valve packages, supplied 20” FB flanged Monel valves for the modernisation programme. These valves were trunnion mounted and suitable for operating temperatures of up to 200oC. Before dispatch, the valves were subjected to a process of ultra-cleaning to remove all grease and any other materials that might react with the oxygen.
