【Major Chemical Equipment Innovations】285 – China’s first fountain-type internal pipe welding waste heat boiler
Thread Content
December 1, 2017: China’s first spray-type internal pipe welding waste heat boiler was developed. China’s first waste heat boiler to utilize fountain-type pipe interior welding was produced by Harbin Electric Group and sent to Anhui Liuguo Chemical. This achievement overcame challenges such as the high requirements for dimensional accuracy of such products, the complex structure of their internal components, and the limited space available for welding and assembly operations, thus filling a gap in China’s market for similar products.
