Induction Bending

Induction bending by Barnshaws is an advanced metal bending process, offering optimum precision, efficiency and consistency. It is suitable for a very wide range of applications and completely overcomes the potential limitations of cold bending techniques, such as distortion and wall thinning.

Straight pipe, tube or other section types are placed on a machine bed with a swing arm set to the required radius. The material is then hydraulically pushed through an induction coil at a carefully controlled and monitored rate. Heat of approximately 1000°C is solely focused on the area which requires bending, while cool air and water is sprayed on the area adjacent to the heated zone.

The combination of speed, heat and cooling allows sections to be bent to tighter radii without cross sectional deformation.

Typical application sectors:

Power generation – Construction – Ship building – Offshore oil and gas – Petrochemicals – General fabrication

CAPABILITY AND CAPACITY

At Barnshaws, we offer a uniquely comprehensive induction bending service, providing the following decisive advantages: -

Induction pipe bending from 50.8mm (2”) to 813mm (32”) O/diameter, using material up to 50mm thickness.
Pipe and other sections can be curved to smaller radii than with cold bending techniques.
Pipe surface unaffected/unblemished by the process.
Multiple bends possible on a single length of pipe.
Reduced welding requirement with compound bends, improving finished pipework integrity.
Faster and more energy efficient than traditional fire/hot slab bending methods.
A completely controlled and recorded process.
Certification available, describing all key aspects of the induction bending process at a component-specific level, if required.

To ensure the most cost effective and efficient material usage, we provide a material utilisation pre-order analysis. This assists our customers in achieving unrivalled competitiveness and giving them a true edge in the markets they serve.

We can bend pipe from 50.8mm (2”) to 813mm (32”) O/diameter, using material up to 50mm thickness.

Barnshaws has also amassed a wealth of expertise in bending construction beams and 500 x 300 RHS, using this highly capable and versatile technique.
