Orseal, a flow control solution company, has delivered its oxygen (O2) service valves to IISCO Steel Plant’s (ISP) fully-integrated iron and steel facility in West Bengal, helping increase its profitable steel capacity to 2.5 million tonnes per year.

The Special Projects Division of the UK-based business, which designs and manufactures customised valve designs, supplied the 20-inch floating ball (FB) flanged valves for ISP’s modernisation programme.

The valves, manufactured in Monel due to its strength and corrosion resistance properties, are trunnion mounted and can operate in temperatures of up to 200°C.

The valves have proven to be extremely reliable, rugged and efficient in a plant where the very highest standards of safety and performance are absolutely vital

A spokesperson at Orseal signified, “It’s vital for companies supplying valves to the steel industry to have a thorough understanding of system processes and material properties. The steel industry, where oxygen (O2) service valves are needed, has benefitted particularly from Orseal’s hazardous area expertise.”

“The valves have proven to be extremely reliable, rugged and efficient in a plant where the very highest standards of safety and performance are absolutely vital.”

The valves underwent a vigorous ultra-cleaning process in order to remove any impurities that could react with O2 before being dispatched to the Indian state.

The plant (below), which is one of the oldest in India, is currently undergoing the final stages of its INR 16,480-crore ($2.5bn) modernisation and expansion programme, aiming to raise its saleable steel capacity to 2.5 million tonnes per year.
