Huaye Heavy Industry Manufacturing 1420 Expanding Machine Russian Debugging Successfully Completed

Thanks to the joint efforts of the Huaye Heavy Industry team and the close cooperation of the Russian customer, the on-site commissioning of the 1420 expander has been successfully completed. During the commissioning, the team overcame multiple challenges, including language communication, cultural differences, and the complex on-site environment. Through fine-tuning and continuous optimization, the team ensured that all performance indicators of the expander met the expected standards, providing solid technical support for the Russian customer's production line upgrade.

This machine is a dedicated equipment for spiral submerged arc welded pipe production lines. It is used to expand the ends of the produced spiral submerged arc welded pipes, so that the diameter and roundness of the pipe ends within a certain length meet the allowable range. The maximum wall thickness of the expandable steel pipe12mm，the maximum diameter of the expandable steel pipe φ 529- φ 1220 mm ，the maximum length of the steel pipe allowed to pass 12500 mm 。 This expander is a dedicated equipment for spiral submerged arc welded pipe production lines.
