By using HX-series orbital weld heads from Orbitalum, pipe elbows can be joined to small stainless-steel pipes, e g. in heat exchanger constructions, with a high level of efficiency and reliability. Orbitalum is expanding this series to include the HX 12P, which is specially designed for very compact fin heat exchangers using pipe diameters from 9.5 to 13.3 mm.
Pre-mounted pipe elbows, even those in tight pipe bundles, can be welded reliably and quickly with this technology. Thin-walled stainless-steel pipes with wall thicknesses of 0.5 to 0.8 mm can be processed. Compared to manual work, the preparation time is reduced by around 50 %. The welding time is only around 30 s per pipe, and up to 250 welds per head and layer can be made in this way. HX heads make it possible to build very compact heat exchangers with a high pipe density and thus a high degree of efficiency. Pipe spacings of less than 40 mm are possible.
To facilitate handling, Orbitalum heads are connected to the welding power source with a flexible 7.5 m hose. The HX 12P also scores with its straight design, which enables easy turning of the head at the heat exchanger.
