    High Precision SUS302 Tube Mill Line , Ss Tube Mill Machine 0-8M / Min BG20



    Description of product


    This equipment is specially used for producingΦ8-Φ25.4mm, δ0.5-1.5mm stainless steel straight seam welded pipe. It made by refined materials in high precision and equipped with fixed length cutting saw. The main machine includs forming, welding ,sizing and straightening device. The composition of equipment is from uncoiler to fixed length-cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.

    6. Power and air supply. (380V/50HZ)

    Introduction of main components:



    Structure type: Double-side 360ºrotary manual expanding tight, which insure steel coil feeding alternatively and make steel strip going into accumulator freely.

    Applicable range: 25-80mm steel strip width, 0.5-1.5mm thickness, Φ600-Φ1000mm steel coil O.D., Φ450-Φ550mm steel coil I.D., Max.500kgs steel coil weight.

    1.  Shearing and butt-welding machine, which insure double steel coil shearing tidily and then welding together and leveling weld seam.
    2. Forming, welding and sizing unit:

    Feeding & leveling device:


    Form: Five rolls are passively leveled for straightening strip steel before it is fed into forming unit.


    Forming device:


    Mainly roughly mill-forming steel strip and controlling weld seam.

    a. Horizontal roll stand: (Three fin pass)

    Quantity: 8
