ERW pipe making machine series are high frequency longitudinal welded pipe production pe making machine / tube mill 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 ly 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.
Please us for customized proposals with all detailed information.

Round pipe | Cold roll forming process | Good roller design |
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 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. |
