PRODUCT DESCRIPTION Welded tube mill in the process of manufacturing square pipes, rectangle pipes with direct shaping and molding technology, combined type rollers are used with pieces structure, roller sleeves are filled between roller pieces, In the deformation region, rollers contact strip steel partially not fully, reducing the contact area and reducing the friction between strip steel and rollers accordingly. As a result, roller consumption is little and the energy consumption of units molding is also reduced remarkably accordingly. According to users needs, the welded tube mill machines can be designed into the multifunctional combination equipments for producing section steel, square pipes and round pipes, realizing one machine with multiple functions. Value highlights:  The roller sharing rate is as high as 100%; Eclectic adjusting the roller spaces; Save about 4% of steel material; Main technical parameters Model Material of strip steel: carbon steel of 580Mpa, 350MPa and low alloy steel of X80 Molding speed m/min Specification of square pipe Specification of round pipe Pipe diameter mm Wall thickness mm Pipe diameter mm Wall thickness mm LW400 40 40~100 100 2.0~5.0 50~ 140 2.0~5.0 10~60 LW640 60 60~160 160 2.0~6.0 60~ 165 2.0~6.0 10~50 LW800 80 80~200 200 3.0~8.0 108~ 219 3.0~8.0 10~35 LW1000 100 100~250 250 3.0~10.0 114~ 273 3.0~10.0 10~35 LW1200 150 150~300 300 4.0~12.7 165~ 377 4.0~12.7 6~30 LW1600 200 200~400 400 6.0~16.0 219~ 508 6.0~16.0 6~20 LW2000 300 300~500 500 8.0~18.0 325~ 610 8.0~18.0 6~20 If you are interested in it, please click Shijiazhuang Zhonghui Cold-Forming& Pipe-Welding Equipment Co., Ltd.
