Alliance to supply large pipe lines PRESS manufacturer Schuler and plant construction company Weldec have formed an alliance to supply equipment to pipe mills. Under the name Pipe Alliance, the two companies will offer a range of solutions for the production of large longitudinal welded pipes (LSAW), for example for the construction of pipelines. The product spectrum ranges from stand-alone machines and production lines to the modernisation and overhauling of equipment. Schuler has decades of experience in hydraulic press construction and project management, while Weldec has know-how in the set-up, commissioning and modernisation of LSAW production plants. With Schuler’s global presence, Weldec and its sales partner will now be available as a contact partner for customers in numerous time zones and languages, even after projects have been completed.

“The cooperation will enable us to design and install the best-possible solution for efficient pipe production,” explained Weldec CEO Jörg Heinrich. “This means we can guarantee optimal processes and economic production start-ups.” Schuler’s managing director, Dr Martin Habert, added, “This alliance offers customers around the world an unparalleled level of performance, aimed at ensuring the sustainable and economic production of top-quality pipes.”

High-performance tools for the tube and wire industry

PARTICULAR demands are placed on steels that are used in the low temperature range: they have to withstand temperatures down to -196°C. To date, austenitic steels have been used. However, because of their low yield strength, these are subject to the risk of early deformation and must therefore be cast with very thick walls. This was the starting point for the development of the new low-temperature material Dux Cryo ® , which displays higher strength values with good toughness. The advantage for use is that the casting can be constructed with thinner walls, saving both weight and costs. Schmolz + Bickenbach Guss has started using martensitic steels for jobs in the low-temperature range, as a result of an extensive research project. These materials are excellent for tempering and therefore also display higher yield strength (Rp0.2 ≥ 490N/mm²) than the alternative of austenitic steels – a property that is particularly advantageous in such extreme temperatures. However, particular demands are placed not only on the strength but also on the toughness (KV (-196°C) ≥ 40J). The prerequisite for high strength at low temperatures is a low content of selected trace elements. Otherwise, the segregations caused result in embrittling of the casting.
