A new high capacity induction bending machine means Barnshaws can for pipes up to 32” diameter for end users in the oil and gas, structural and machinery markets.
Induction bending overcomes many of the problems usually associated with cold bending pipes, such as wall thinning and distortion of the section. Instead, a coil heats a focused area of the pipe, and immediately afterwards cold water is applied to cool the newly curved shape. This results in a tube bending process which allows tight radii to be achieved without compromising the integrity of the pipe.
Preserving this internal profile on such a large scale is ideal for end users. Sections with consistent internal profiles can be used on pipelines as they do not constrict flow, whilst also minimising welding requirements. This is especially important for end users, as eliminating fabrication steps provides an expedited solution.
As well as tackling large pipes, Barnshaws can also offer the same induction pipe bending service down to 2” sections. Furthermore, due to the versatility of the process, multiple bends can even be incorporated on the same section. This can include different radii if required, allowing end users to specify the perfect pipe section for their needs. Full traceability is offered as standard, as well as all relevant certifications.
The new machine represents a large investment for Barnshaws. Increased demand for precision curved steel tubes has pushed the business towards expanding its operational capacity, which is already supplemented by some of the most specialist bending machines on the planet. This inherent bending capacity means that Barnshaws customers can expect shorter lead times on orders, as well as improved capability. Enhanced capability now means that Barnshaws can easily take on tube bending for larger pipeline projects, which are prevalent in the oil and gas sectors.
Greg North, Commercial Director at Barnshaws, said: “This new induction bending machine is one of largest of its kind, and gives us increased ability to support requirements for pipes in demanding industries. Our focus on metal bending quality and accuracy means we are well placed to service customers in a variety of sectors, where fabrication standards are high. While we operate a number of similar machines, we are constantly looking for ways to improve our service, and offer more choice to our customers.”
