Graebener Reika offers large pipe forming presses especially suited for line pipe production.
Graebener-Reika, Inc., (GRI) a provider of machinery for processing tube, pipe, bar, plate and sheet, offers its Graebener Maschinentechnik pipe forming presses for producing large diameter line pipe used in pipeline or utility distribution systems. According to the company, these presses are suited for producing pipes with increased yield points and large wall thickness-to-pipe diameter ratios, where the forces required exceed the physical limits of traditional roll bending machines.
"A key advantage of the Graebener press is its ability to form an extensive range of pipe sizes without having to change the tool, providing both a production and price advantage," said a company spokesperson. It can process large format plates into pipes with a diameter range of 16" to 64", lengths up to 60', wall thickness of up to 2.92" and grades as challenging as x1200 and x120. For regular wall thickness applications, a special bending shoe can be used to adapt the machine.
In the Graebener process, the longitudinal edges of the metal plate are first given a chamfer. Then, through a series of steps, the plate is bent into a final "O" shape, creating an open tube that is first tack welded and then submerged arc welded (SAW) at a separate station. This approach has proven to be a cost-effective and flexible methodology for producing high-quality tubes, said the company.
In addition to the Graebener Maaschininentechnik forming press, GRI can support the entire pipe forming process with post-forming machines that include root-tack welding presses, edge bending presses, straightening/calibration presses, end-facer/bevelers, hydrotesters and more.
