expansion.
Advantages: Fast loading, simple and convenient operation.
Hydraulic Shear and Butt-Welding Machine
Function: Cuts the front and rear ends of the strip, centers the
strip, and welds it back together.
Construction: Manual hydraulic shear with boom, front and rear
pressure rollers, front and rear centering rollers, welding device.
Cutting Method: Hydraulic shear
Pressing Method: Double-cylinder press
Welding Method: Manual welding
Coil Accumulator
Function: To ensure continuous production of the welded pipe, a
storage unit is installed after the shear and butt-welding platform.
It continuously feeds the strip while the material is prepared for
loading, unwinding, cutting, and welding.
