ZTZG No-Roller-Change Process Welded Pipe Production Line

ZTZG 26 Years Focused on Welded Pipe Production Machinery

Provide professional ERW pipe mill production lines for downstream steel pipe, steel structure and cold-formed steel manufacturers.

ZTZG independently developed, designed and produced an automated round pipe welded production line without changing the roller、Round to Square Share-Roller Pipe Production line、DFT/Direct Square Forming Share-roller Pipe Mill Line.

Round-to-Round Share-roller Pipe Mill /Pipe Production line /pipe making machine

For producing ordinary carbon steel round pipes, the forming section rollers before welding are shared. When changing to different production specifications, there is no need to disassemble and replace the rollers; only the sizing section roller needs to be replaced.

For producing stainless steel round pipes and low-carbon steel pipes using submerged arc welding, because the welding speed is slower, it is possible to achieve Share-Roller production throughout the entire line. That is, for producing steel pipes of different specifications, the rollers are shared throughout the entire line, and electric adjustment is also possible.

Round to Square Share-Roller Pipe Mill / Pipe Production line

When producing round tubes of different specifications, the rough forming and fine forming rollers before welding are shared.

When producing square and rectangular tubes within a certain range, no roller changes are needed in the forming section before welding.

The sizing section adopts a misalignment adjustment method, allowing online adjustments to produce different specifications of square and rectangular tubes.

DFT/Direct Square Forming Share-roller Pipe Mill / Pipe Production Line

This is a new, fully automated, roller-share square tube production line. It is suitable for producing medium to large-sized square and rectangular tubes ranging from 200 to 500 square meters.

It is a fully automated welded pipe production line that requires no roller changes.

The production of square and rectangular tubes of different specifications can be achieved by adjusting and changing the rollers online via a motor. This significantly reduces roller costs and improves production efficiency. The mechanized adjustment precision is higher, resulting in more regular tube shapes.

The ZTZG frame-opening direct square forming tube making machine, a fully roller-share tube-making line, is a welded pipe production process developed for producing small to medium-sized square tubes (40-150 square meters).

The rollers are connected to the frame via flanges. Moving the frame changes the relative position of the rollers. Switching between different product specifications is achieved by adjusting the opening and closing of the frame via a motor and reducer.

Therefore, production specifications can be switched without changing the rollers.
