  ZTZG Round to Square Share-Roller tube Mill

  This ZTZG's jointly developed, designed, and manufactured "Round-to-Square Tube Production Line Without Roller Change" can produce round tubes, square tubes, and rectangular tubes without requiring roller changes. 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. This significantly reduces roller costs, improves production efficiency, and greatly enhances economic benefits for tube manufacturers!

  ZTZG Direct Square Forming Share-roller Tube Mill

  ZTZG's new direct-forming, roller-share tube-making machine 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. It can produce square and rectangular tubes of different specifications, with the rollers driven by a motor allowing for online adjustment and modification of production specifications. This significantly reduces rollere costs and improves production efficiency. The mechanized adjustment precision is higher, resulting in more regular tube shapes. Manufacturers of large-diameter square and rectangular tubes for building structures, industrial machinery, and transportation should definitely learn about ZTZG's automated, mold-free square tube equipment!

  ZTZG Round-to-Round Share-roller Pipe Production line

  ZTZG's Round Pipe Making Machine Without Changing Rollers: For producing ordinary carbon steel pipes, the roughing and finishing rollers before welding are shared. The sizing section uses a quick-change worktable and hydraulic quick-release device, allowing for rapid changes in sizing dimensions. When changing to different round pipe specifications, there's no need to disassemble and change rollers. For producing stainless steel pipes or low-carbon steel pipes using submerged arc welding, due to the slower welding speed, the entire production line can operate without changing rollers. This means that rollers are shared across the entire production line for different pipe specifications, and online electric adjustment is possible. Highly suitable for manufacturers producing multiple specifications in small batches of round pipes!
