Blue Galvanized Steel Pipe Rail Tube Direct Square To Square Pipe Mill

Introduction of Direct Square-to-Square(DSS) Pipe Mill:

DSS technique directly reels the strip steel into square tubes. It has several distinct advantages:

1. It adapts the multi-point bending method, which avoids the axial force and side abrasion, reduces the forming step, and ensures high quality.
2. Compare to Round-to-Square(RS) forming technique, DSS creates better outer edge and smaller inner arc for the cross section of the tube, and the brim is flatter with more regular outlook.
3. With our new DSS-3 technique, only one set of rollers is needed for the entire mill with no need for any roller or spacer replacement, which achieves full-automatic adjustment for roller positions, significantly increasing production efficiency and reducing labor cost and risk of hazard.
