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
At Barnshaws, we offer a uniquely comprehensive induction bending service, providing the following decisive advantages: -
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 508mm (20”) 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.
