Turnkey production lines for pipelines

SCHULER develops turnkey production lines for large pipes, for pipeline applications in crude oil, natural gas, water, petrochemical industry, wind energy systems and construction industry. The company is delivering two spiral pipe mills to Mexico and Saudi Arabia, and an existing line in Canada is being completely modernised. The mills for Mexico and Saudi Arabia are offline spiral pipe lines for the production of large pipes with diameters from 508 to 2,235mm (20" to 88") and lengths of 12 to 24.4m. The pipes are made from high-grade steel (up to X100) with thicknesses of up to 25.4mm, which is wound onto coils. This is formed into a spiral tube and submerged arc welded to a spiral welded pipe. The coil preparation stand ensures short changeover times, a high degree of safety, and an exact 90° cut at the beginning of the coil. Crane transfers are no longer necessary. At the forming station, all relevant steps are automated: the

product quality. With a total length of 450m, the two pipe plants also feature various devices to test the large pipes in accordance with the API standard. This entails the use of ultrasonic, X-ray and hydrotester stands. In cooperation with Swiss company MaurerMagnetic, Schuler hasdeveloped a process that can demagnetise large pipes during production. This prevents deflection of the arc during welding and ensures the quality of the welds, enabling them to withstand the guaranteed loads. Schuler provides presses, automation, dies, process know-how and services for the metal forming industry and lightweight vehicle construction. Its clients include car manufacturers and their suppliers, as well as companies in the forging, household equipment, packaging, energy and electrical industries.
