Traditional pipe manufacturing processes require changing a set of rollers to produce welded pipes of different specifications.
This not only results in low production efficiency and a significant waste of manpower, but also poses a high risk factor.
Furthermore, the large number of rollers accumulated represents a substantial cost for pipe manufacturers.
ZTZG independently developed and manufactured roller-free welded pipe machine revolutionizes the traditional roller-changing structure, achieving a completely roller-free process throughout the entire production line. Filling the gap in roller sharing, it reduces costs, improves quality, and increases efficiency, making it the ideal choice for pipe manufacturers in the new era!
ZTZG Round-to-Round Share-roller Pipe Production Line
For producing ordinary carbon steel 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 pipes and low-carbon steel pipes using submerged arc welding, because the welding speed is slower, it is possible to achieve roller-free production throughout the entire line. That is, for producing steel pipes of different specifications, the rollers are shared throughout the line, and electric adjustment is also possible.
ZTZG Round to Square Share-Roller Pipe Mill line
When producing round tubes of different specifications, the roughing and finishing rollers before welding are shared, greatly reducing the cost of storing rollers and the time spent changing rollers, thus improving production efficiency.
When producing square and rectangular tubes within a certain range, forming also does not require changing rollers. The sizing section uses a staggered adjustment method,
allowing for the production of square and rectangular tubes of different specifications with only online adjustments. Furthermore, the finished square tubes with special structures are of superior quality.
ZTZG Direct Square Forming Share-roller Pipe Making Machine
A fully automated square tube production line that requires no roller changes.
It produces square and rectangular tubes of different specifications. The movement of the rollers or frame is driven by a motor.
Switching between production specifications significantly reduces roller costs and improves production efficiency.
Online adjustment and changes to different production specifications result in higher precision mechanized adjustments and more regular finished tube shapes.
