Boilers for Thermal-power Projects




The T91, TP304H, TP347H, TP347HFG, UNS S30432, HR3C、740H、6230 seamless steel tubes produced byBaoyin for Supercritical/Ultra Supercritical Thermal Power Plants, successfullyreplaced imported tubes and were applied in large scale thermal power plantswith capacity of 600MW and 1000MW. By self-researching and innovation, Baoyinproduced carbon steel and stainless steel U-bent heat exchanging tubes forhigh-pressure water-feed heater in large scale Supercritical/UltraSupercritical Thermal Power Plants with installed capacity of 600MW, 1000MW.The above tubes ranks top one in the world, successfully replaced the importedtubes and were applied to major electrical companies as Dongfang Electric,Shanghai Electric and Harbin Electric. In addition, these tubes are alsoexported into global market, like Toshiba, Hitachi,Mitsubishi in Japan and Babcock &Wilcox in USA。
