Induction bending

Compared to cold forming methods, induction bending minimizes deformation of the material and distortion of the cross-section even when tight radius bends are required.

Induction Pipe Bending

This hot bending process is a preferred alternative to the traditional cold bending process as it limits wall thinning, rippling and ovality. It is the consistency and predictability of this bending process that contributes to the high quality and reliabity of bends. Heat induction bending enables the bending of large pipes, steel beams, as well as square and rectangular tubes.

Our capabilities include multi bend configurations. Chicago Metal Rolled Products can meet some of the shortest lead times, often shipping product within 24 hours. Pipes formed with induction pipe bending by CMRP can be found in applications where little to no wall thinning and minimal ovality is mandatory. Straight pipe is placed in the machine bed with an induction heating coil located around the pipe at one end. This heating coil creates a narrow, circumferential, heated band around the material.

As the pipe reaches the required temperature, it is slowly pushed forward through the coil at a consistent speed and temperature and shaped into a bend. After the material passes through the coil, it is cooled by a controlled water cooling system. Request a Quote.

That is why we use you, fast response to quotes and questions and great quality!The induction bending process, also known as high frequency bending, incremental bending or hot bending, uses inductors to locally heat steel by induction. This results in a narrow heat band in the shape to be bent.

The shape is firmly held by a clamp at the desired radius, which is mounted on a free pivoting arm. The shape is pushed through the inductor by an accurate drive system which causes the hot section to form the induction bend at the set radius. The bent part is then cooled by water, forced or still air to fix the bend shape. The Cojafex induction bending technology ensures that the pipeline bending process is continuous and highly automated. The Cojafex Induction bending technology allows bending of an almost unlimited variety in materials.

The only requirement is that they can be heated by induction. Following steel grades are routinely hot bent on Cojafex bending machines for the industries mentioned below:.

Induction bendable materials The Cojafex Induction bending technology allows bending of an almost unlimited variety in materials. Major advantages of induction bending Cost efficiency. Straight material is less costly than standard components e. Elbows can often be replaced by larger radius induction bends, reducing friction, wear and required pump capacity. Induction bending reduces the number of welds in a system. No welds at the critical points thanks to the tangents. Induction bends are stronger than elbows with uniform wall thickness Stock of elbows and standard bends can be greatly reduced.

Straight pipe is more readily available than elbows, reducing time to market Induction bends can be made from the same base material as the straight pipe. Induction bending does not need bend dies or mandrels. Induction bending process is a clean process. No lubricants necessary. Contact us.Clad pipe, aluminium, copper and brass.

Originally used for the purpose of surface hardening steels, induction technology when used in pipe bending consists basically of an induction coil placed around the pipe to be bent. The induction coil heats a narrow, circumferential section of the pipe to a temperature of between and degrees Celsius dependant on the material to be formed.

As the correct bending temperature range is reached, the pipe is moved slowly through the induction coil whilst the bending force is applied by a fixed radius arm arrangement.

Metal Fabricating Glossary

Induction bends are formed in a factory by passing a length of straight pipe through an induction bending machine. This machine uses an induction coil to heat a narrow band of the pipe material. The leading end of the pipe is clamped to a pivot arm. As the pipe is pushed through the machine, a bend with the desired radius of curvature is produced.

The heated material just beyond the induction coil is quenched with a water spray on the outside surface of the pipe. Thermal expansion of the narrow heated section of pipe is restrained due to the unheated pipe on either side, which causes diameter shrinkage upon cooling.

The induction bending process also causes wall thickening on the intrados and thinning on the extrados. Most induction bends are manufactured with tangent ends straight sections that are not affected by the induction bending process.

Field welds are made or pipe pup sections are attached to the unaffected tangent ends, allowing for fitup similar to that found when welding straight sections of pipe together. Induction bends come in standard bend angles e. Compound bends out-of-plane bends in a single joint of pipe can also be produced. The bend radius is specified as a function of the diameter. For example, common bend radii for induction bends are 3D, 5D and 7D, where D is the nominal pipe diameter.

ASME B This standard covers induction bends for transportation and distribution piping applications e. Process and power piping have differing requirements and materials that may not be appropriate for the restrictions and examinations described herein, and therefore are not included in this Standard.

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

The heat band eliminates the risk of pipe wrinkling and normal bending is carried out without the use of mandrels or formers, thanks to the robust support provided through the cooled pipe on either side of the narrow heated section. Pipes do not develop scaling during the process and even previously scaled material can still be bent as efficiently as pipe or tube in perfect condition. This remarkable flexibility also extends to previously rusted, seam, butt or spiral welded material.

Varying material wall thickness can also easily be accommodated, using appropriate machinery adjustments during manufacture.
