    Technical Advantages
    Dalian SAGE Technology Development Co. produces equipment with international leading technique including common metallurgy equipment, Cage Forming Large-diameter(1420mm)HF Welded Pipe Mill, Cold Sizing Stretching and Reducing Small-diameter(?4.76mm)Square Wave Welded Pipe Mill, Oil Pipe(Adopting API)Submerged Welded Pipe and so on.
    Large-diameter Submerged-Arc Welded Pipe Mill which produces the largest diameter is 1420mm and the annual yield is 300,000 to 500,000 tons with Cage Forming and UOE technique.
    The welding speed of H-beam Steel Production Line with HF welding method is up to 37m/min,one production line is equivalent to more than ten H-beam production lines with submerged-arc technique. The annual yield is up to 100,000 tons.
    The rolls produced by Dalian SAGE Technology Development Co. carry out digital control finishing crafts increasing the geometry size precision .The life of rolls increased to several times or more than ten times with the material of Cr12MoV than common rolls.
    Dalian SAGE Technology Development Co. has international advanced technique in automatic control. PC general wires industry control machine and PLC controlled all main parts. All DC Speed Regulating Devices carry out digital device. The technical level is high, the reliability is good, the rate of fault is low.
    ICS computer-controlled length cutting off system designed by Dalian SAGE Technology Development Co. is national invention patent and international initiation. Its character is to adopt non-contact testing method to insure the length of irregular cross section such as cold forming steel and profiled strip welded pipes.

    Two advantages—super quality, low price
    Dalian SAGE Heavy Industry Machinery Co. Ltd makes full use of advanced technique of international developed countries and combines our designing ability to let customers get the international leading level equipments with lower price than international market(usual lower 1/2 to 7/8) with the model of Foreign-China –Foreign. High quality and low price are common desire and pursuit of us and customers.
