Product Details

ERW round pipe square pipe rectangular pipe steel pipe production line

ERW pipe making machine series are high frequency longitudinal welded pipe production line / pipe making machine / tube mill line that designed to produce welded pipes of 8mm-720mm in OD and 0.3mm-22mm in wall thickness, as well as corresponding square and rectangular pipe.

This series pipe line mainly including below models:ERW20/32/50/76/89/114/140/165/219/273/325/377/406/508/660/720

We also can design and manufacture pipe making machine according to customers' requirements.

This series machine can produce:GI, carbon steel and stainless steel tubes for metallurgy, construction, transportation, machinery and vehicle industries.

Forming process

Round pipe	Cold roll forming process	Good roller design
Round pipe	ZTF forming technology	Reduce 60% roller cost, save roller changing time, increased production efficiency
Square & rectangular pipe	General round-to-square process	Stable forming process
	Round to square with turkshead	Good pipe quality, reach same wall thickness with round pipe
	Directly squared forming technology	1) Compare with round into square&rectangle forming way,this way is better for the shape at the edge of cross section,comparatively, semi-diameter of inner arc is Small,and the brim is flat,outlook is regular. 2) the whole line load is low ,especially the sizing parts. 3) The width of steel strip is small about 2.4-3% than round into square & rectangle,it can save the consume of raw material. 4) It adapt the multi-point bending way, avoid the axial force and side abrasion, reduce the forming step while ensure the quality,meanwhile it reduce the power wastage and roller abrasion. 5) It adapt the combined type roller on the most of the stands,it realize that one set of roller can produce dozens of square&rectangle pipe with different specification,it decrease the store of roller,low the cost about 80% on roller, Fast the bankroll turnover, short the time one new product design.
