Typical applications for heat exchanger tubes are coolers, heaters, evaporators, condensers and recuperators in harsh environments.
The tubes are supplied according to appropriate standards as well as customer specifications in a large variety of steel grades and dimensions. They are made from strips, mainly laser welded without filler metal, delivered in annealed condition in fixed lengths.
