Pipe Production Line Consists of:
Dual-Station Decoiler
Function: Passively unwinds the coil.

Construction: Dual-station design with 180° rotation; manual 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.
