PRODUCTION LINE OF LARGE DIAMETER STRAIGHT SEAM WELDED PIPE

摘要

A production line of large diameter straight seam welded pipe is composed of a material storage platform (1), a charging trolley (2), an uncoiler (3), a leveler (4), a shearing butt welding machine (5), a movable sleeve (6), an edge milling machine (7), a steel plate crack detector (8), a lifting platform (9), a steel pipe shaping machine (10), a welding device (11), a pulling device (12), a heat treatment device (13), a cooling device (14), a rigid rolling machine (15), a cut-to-length type cutting machine (16) and a discharge platform (17). The production efficiency of the production line is improved, the product quality is stabilized, and the manufacturing cost is reduced. The production line can run reliably and facilitate the operation.
