Un-coiler

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.

Strip Accumulator

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.

Straightening Machine
