Manufacturing Technologies of Finned Tubes


The increase in demand for electricity in Europe requires a continuous search for new sources of energy, engineering and technology solutions. Maintaining the current level of electricity production requires not only repair and modernization of the operating units, as well as construction of new blocks of supercritical and ultrasupercritical. Increasing thermal efficiency while reducing energy costs is possible through the use of finned tubes for heat exchangers. This paper presents the technologies of finned tubes, with particular emphasis on innovative laser welding technology developed in the Energoinstal SA company. The use of high power disk laser allows the welding of finned tubes several times more efficient compared to arc welding technology, while maintaining stringent quality and technical requirements.
