Largest bender installed in Norway

This 273 mm Unison all-electric bending machine – the world’s most powerful – was installed at Westcon Yard’s Olensvag facility in November 2015 Unison has installed and commissioned the world’s largest and most powerful all-electric pipe bending machine, at the Norwegian offshore and maritime services company, Westcon Yard AS.

Capable of generating 660,000 Nm of continuous, servo-controlled torque, the custom-designed machine will be used for precision bending of thick-walled carbon steel pipes up to 10 inches (273 mm) in diameter.

This is the second all-electric pipe bender that Unison has supplied to Westcon’s pipe production facilities in Olensvag, Norway. The first, a 90 mm single-stack model from Unison’s Breeze range, was installed at the beginning of 2015 and enabled the company to bring fabrication of all pipe sizes up to 60.3 mm in diameter in-house. It has also helped Westcon to simplify and accelerate its production process dramatically, by allowing parts to be fabricated from single-piece piping stock, instead of from multiple cut-to-length straight sections and pre-formed bend parts bought-in from external suppliers.

Westcon has similarly high expectations for its new 10-inch machine. The company now intends producing virtually all the pipe sizes that it needs for its outfitting, service and repair operations entirely in-house, without having to use pre-fabricated bend sections.

This application of all-electric bending technology to pipes up to 10 inches in diameter is without precedent. Although Unison’s bending machines are used by a number of the world’s leading ship and submarine builders to produce large pipe and tube assemblies, this is by far the most powerful that the company has ever designed and built. It highlights the inherent scalability of Unison’s machine architecture and underlying motion control technology – the company’s range of all-electric bending machines now extends all the way from 16 mm (5/8 inch) to 273 mm (10 inches).

The order for both pipe bending machines, which also called for Unison to supply CAD support software, was placed through P Meidell AS, the specialist machine tool company that acts as Unison’s representative in Norway.
