Frequently Asked Questions
This line is specifically engineered for strip steel grades Q195 to Q345, with a thickness range of 2.0mm to 5.0mm.
The flying saw allows for cutting the pipe while it is still moving at speeds up to 80m/min, eliminating the need to stop the line for each cut.
The straightening machine uses a four-column frame to eliminate residual stress and physical bending that occurs during the welding and cooling phases.
While this specific configuration is for φ76-φ89mm, we offer customized roller designs and equipment layouts to meet specific diameter requirements.
Due to the use of GCr15 and 40Cr quenched steel, wear is minimized. Routine lubrication of the gearboxes and periodic inspections of the roller surfaces are recommended.
The cage looper acts as a buffer zone, storing raw material to ensure the forming and sizing machines operate continuously without interruptions.
