摘要

At Tube Southeast Asia, Fontijne Grotnes will promote its newly developed straightening system for mechanical expanders. This machine controls the straightness of pipes in all directions, where other systems only control straightness in the plane of the weld-seam. Tolerances for ovality and straightness of pipes are becoming increasingly important to simplify the later laying of pipes in the field. This also applies when pipe sections are cut in the field as the pipes are sized over their full length.
