The tube clamping system closes the gap between tube and the borehole and positions the tube centrally within the borehole without heat input or the use of additional material—the foundation for defect-free welds.

Pipe edge milling cuts tubes precisely to size—both before welding and after expanding. When repairing heat exchangers, it also removes old welds before pulling out the tubes.

Automated TIG orbital welding replaces the manual welding of tubes into the tube sheet—with repeatable precision, consistently high quality, and significantly reduced repair costs.

Whether it’s joint rolling after welding or sealing rolling—the key is to ensure that the bond expansion is achieved reliably and consistently by following established procedures and using appropriate machinery and tools.
