Pipe and Vessel ConstructionHydraulic PressesShipbuilding

Varying demands, shorter project lead times, smaller lot sizes and ever increasing requirements. In view of these conditions, it has become nearly impossible for even the most experienced pipe and vessel manufacturing companies with outdated technology to compete with new production technologies in terms of productivity, quality, consumption of operating media etc. Machines such as for example 3- and 4-roll bending machines or pipe forming presses, which have already been in operation for several years, reach their technological limits when it comes to productivity and flexibility. Forming high-strength material is very difficult, sometimes even impossible.

Graebener® retrofit solutions offer a new perspective. A substitution of outdated machines against new ones not only means high investment costs but also considerable production downtimes. The alternative is a Graebener® retrofit: a comprehensive modernization of existing machines or entire pipe production lines to meet the latest technological standards – either in several stages so as to encumber the production as little as possible, or within a reasonable time frame -  for example during company holidays.

Graebener® retrofit solutions have been successfully implemented worldwide. Starting point for each solution is a holistic machine and condition analysis which forms the basis for our advice regarding your individual options and chances.

Torn press block, inefficient hydraulics, outdated control technology and, in the worst-case scenario, all of the above at the same time. There are many reasons why your hydraulic press no longer is equipped to meet the current requirements. But there is no reason to accept this situation. A Graebener® retrofit is the economic solution to circumvent unnecessarily high investment costs for a new press and still remain competitive. Based on our experience in the construction of hydraulic presses for more than 30 years and a holistic machine approach we return your press to state-of-the-art technology. Standstill means loss. Graebener® retrofit means technological edge.

Our know-how is also based on the experiences gained from our own Prototyping Center providing four hydraulic presses with closing forces between 1,500 t and 10,000 t. Operation and maintenance training and instructions are conducted at our workshop or at the workshop of our customers worldwide.

Hydraulic presses of each type – even those of other manufacturers – can be retrofitted to the latest technological standard and on request updated with unique and unmatched solutions regarding the pioneering big data issue in the sector of smart process analysis. The overhauling of the oil and high-pressure hydraulics as well as the modernization of control and feedback control systems are major aspects of our retrofitting works. Presses retrofitted by Graebener® impress with reduced loading and cycle times as well as with improved quality.

Retrofitted presses are measurably more cost-efficient, productive, safer and, not least, more reliable. Our references worldwide can attest to that.

With the commitment of steel suppliers to develop steel grades to meet the growing demand for innovative ship design, ship builders are facing new challenges. New steel grades call for innovative production processes to remain competitive. Only a few production lines are up to this challenge and buying a new production line might be too big an investment. The solution is: Graebener® Retrofit – a comprehensive modernization of existing panel production lines based on the state-of-the-art technology.

As regular supplier of the German Meyer Shipyard and developer of the patented Tailor-Welded-Plates (TWP®) technology, we meet your individual challenge with our vast know-how in the sector of ship deck production. Starting with the highly precise plate edge processing by means of modern milling technology up to innovative joining processes such as laser-hybrid welding; we provide competent and extensive advice regarding your choices and options based on a holistic analysis of your existing lines.
