Hamburg Bending Process
The Hamburg process’s main advantage over the conventional induction process is the resulting low ovality. This makes the elbow segmentable and piggable. In addition, these elbows have a well-defined and very precise inside diameter, as well as a more even distribution of wall thickness. There is also a cost advantage in comparison to the induction process, due to reduced wall thickness.
On the other hand, the Hamburg bending process requires a separate mandrel for each bend radius, which can have a negative impact on costs. Erne Fittings has a decisive advantage here in that its decades of experience have allowed it to assemble the world’s largest collection of mandrels.
