Our Company

Shijiazhuang Zhongtai Pipe Technology Development Co., Ltd.was established in 2000 locating in Shijiazhuang, the capital city of Hebei Province. The factory covers an area of 67,000 square meters. Our main products consist high frequency straight welded pipe production line, cold roll steel production line, multi-function cold roll steel/welded pipe production line, slitting line production line, stainless steel pipe mill, various pipe mill auxiliary equipment and rollers, etc.
Lean more...Compare to Round-to-Square (RS) forming technique, the Flexible Cold Forming (FCF) creates better outer edge and smaller inner arc for the cross section of the tube, and the brim is flatter with more regular outlook. 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.Steel pipe manufacturing process
