Steel pipe rolling mill machine

Steel pipe rolling mill machine is used to manufacture welded steel pipe of Φ76-Φ165with 2.0mm-8.0 mm of wall thickness, can produce profiled pipe also within the limit of processing round pipe. After we absorbed advanced pipe making technology from both abroad and domestic, our innovative designed production line and each single unit of the production line is not only economical but also practical. 
Our Steel pipe rolling mill machine technology characteristics:
(1) It can save 60% cost on rollers.
(2) One set of roller can be used to product all round pipe range from Φ76 to Φ165 in breakdown section. And roller in breakdown section needn`t be changed, just change rolls in fin pass section (section after closure rolls) when produce a different size of pipes. 
(3) Cut down production Time.
(4) It`s easier to repair rollers.
(5) It is convenient to restore and adjust roller.
