High Strength Steel Drain Pipe Long Service Life Square Pipe Mill
Direct Square to Square Pipe Mill Introduction:
It is directly roll the steel strip and bend it to square & rectangular shape, then weld it to finish the formation.It has several distinct advantages:
1.Compare with round into square & rectangle forming way, this way is better for the shape at the edge of cross section, comparatively, semidiameter of inner arc is Small, and the brim is flat, outlook is regular.
2.the whole line load is low, especially the sizing parts.
3.It adapt the multi-point bending way, avoid the axial force and side abrasion, reduce the forming step while ensure the quality, meanwhile it reduce the power wastage and roller abrasion.

Square Tube Mill Auxiliary Machines:
Customers can trust us to buy the auxiliary machines. Our choice of suppliers for the auxiliary parts is made after 22 years of experience.
Function: Used for supporting strip steel coil and open it as strip steel so as to make preparation for the pipe forming process.
Shearing butt welding
2 Types: Automatic & Manual
Function: Shear & end welder parallel cuts the head of the strip coming out of uncoiler and the tail of the strip steel going into the accumulator, and weld them together to form a smooth and continuous line of strip steel.
Function: Accumulator is used to accumulate strip steel from uncoiler and provide strip steel to forming unit. It leaves time for the shear & end welder for strip welding and stores certain amount of strip for continuous forming.
Solid State High Frequency Welder
Function: The welder is used for welding edge heating with high-frequency heating device. The whole set of solid-state H.F welder comprises of rectifying cabinet, inverter, output cabinet, connecting optical fiber, closed loop water cooling system, central operator console, and mechanical adjustment device.
Saw Cutting System
Function: Flying saw is used to cut tube during static and motion status in continuously production into desired length.
Function:Straightening machine is a finishing equipment for the high-frequency straight seam welded pipe production line, which is used to straighten the steel pipe to eliminate the stress and bending after the steel pipe forming and welding.
Automatic Stacking and Packing Machine
Function: Electrical control using PLC control, touch screen, to achieve human-computer dialogue, manual, automatic between the free conversion.
