Tuberias Procarsa, one of the leading manufacturers of steel pipe in Latin America, with headquarters in Monclova, Coahuila, announced it has put a spiral pipe plant in operation to produce large-diameter pipes.

The offline spiral pipe plant can produce large-diameter pipes with a diameter of 508 to 2,235 millimeters (20 to 88 inches) and a length of 12 to 24.4 meters. The raw material up to 25.4-millimeter-thick sheet metal band made of high-quality steel comes on a hot rolled coil (HRC). 

The spiral mill forms the diameter and welds the spiral pipe within the first step by tack welding.  In a further process, the final pipes will be weld by several final welding stands with a submerged arc welding process.

The production line from Schuler features an integrated coil preparation stand, which ensures short changeover times, high occupational safety and an exact 90-degree cut of the beginning of the band. A crane transfer is no longer necessary. All relevant work steps on the spiral mill are automated: settings are no longer made manually; instead, setting is done directly on the well-organized control panel and implemented by servo motors. This results in an energy savings of up to 30% and short changeover times.

At a length of 285 meters, the pipe plant also includes various equipment for inspecting the large-diameter pipes in accordance with the API 5L standard. Ultrasonics, X-rays and water pressure stands are used here. The production capacity of Tuberias Procarsa will be increased by 200,000 tons a year thanks to the Schuler system.
