Forming & sizing pipe mill

Make sure the welded pipe mill line working continuously and high speed,besides the forming & sizing machine machines ,they are necessary ,such as the uncoiler /decoiler ,cutting & welding machine ,clamp & feeding machine ,the accumulator , the flying saw ,the end-facing machine and the straightener ,even the bench & roller table .  

Layout of the production line

Forming & sizing mill is the main mill of the whole pipe production line. Composed of forming roll stands, guide roll stand, squeezing roll stand, bur scrapers, sizing roll stands, and rough straightening roll stands, forming process is to roll the strip into pipe shape, high-frequency welder is to weld the pipe edges under the guide of guide rolls, and almost immediately squeezing rolls squeeze pipe edges together, the outer bur scrapers scrape clearly pipe outer burrs, the sizing process guarantees perfect precision of pipe sizes, and finally rough straightener(s) is(are) to longitudinally straighten the pipe.

Introduction
