New pipes by CENTRAVIS for chemical plants

In order to improve performance of the existing heat exchanger tubes, CENTRAVIS has developed a novel technology of double quenching of the material (02Ð¥22Ð?5Ð?М3, a Russian analogue to duplex 1.4462/UNS S31803), and in 2014 initiated five-months long corrosion testing, which has proven that the material has superior performance against all types of corrosion, as well as excellent mechanical properties.

Heat exchanger tubes of this duplex steel manufactured by CENTRAVIS allows customers to decrease both direct (regular replacement of the tubes) and indirect (repairs and idle times affecting productivity) costs due to significantly higher corrosion resistance of the material of up to 2.8 to 2.9 times. As a result, operational life of the heat exchanging equipment would increase threefold, leading to the estimated economic benefit of over USD 500,000.

“Technological solutions that we offer make it possible for chemical industry companies increase their equipment’s lifecycle, cut production costs and achieve better performance”, said Viacheslav Erkes, CENTRAVIS sales director.
