Mohn Piping (FMP) to improve the production accuracy, and bore hydraulic piping systems. The machine is also designed to help the company improve reducing the number of steps required to fabricate piping parts. manufacturing facilities in Frekhaug, Norway, the custom pipe bender is one of the most powerful all-electric machines that Unison accommodate tubes and pipes up The machine’s exceptionally high torque capability, combined with sensing clamp and pressure dies,

means that thick walled pipes made from hard materials can be bent easily, and very accurately without from duplex stainless steel are a typical example – the machine diameter pipes that have a wall pipes that are used in the well- known ‘Framo’ brand of submerged pumping systems for shipping, applications. It also produces a diverse range of hydraulic pipes for industry.
a bending solution that could accommodate a range of fabrication materials and wall thicknesses for the production of large diameter pipes, as well as addressing a
particular manufacturing issue diameter thin-walled stainless steel pipes. The company has been machines to produce these pipes, but with one of them it was proving bends without wrinkles, despite the use of a mandrel, because there was the rotary-draw bending process. Although the other machine was capable of handling the bending tasks, it was relatively old and obsolescent components was becoming time-consuming and threatening to cause production bottlenecks.
According to Helge Kolas, machine. The technology has a number of important advantages over hydraulics, including faster

setup, better process accuracy and repeatability, and much thoroughly researching the market we chose a Unison machine because the company has a long history of producing all-electric benders that are consistently ahead of the competition, and was prepared to work with us to create a custom machine that met our needs exactly.” a single-stack, right-hand bend model, equipped with Unison’s innovative laser springback system manufacturing by automatically compensating for the tendency of tubular parts to spring back slightly after being bent. The bending head is designed for exceptional rigidity to accommodate large, heavy pipe assemblies and to allow fully automated movement of the pipe in all working planes. Despite
