Our high-performance Welded Pipe Production Line is an industrial-grade solution engineered for precision, durability, and high-volume output. Designed specifically for the processing of Q195-Q345 strip steel, this comprehensive system integrates advanced forming, welding, and sizing technologies to produce seamless-quality welded pipes with exceptional structural integrity and dimensional accuracy.
From the initial uncoiling and hydraulic shearing to the final precision straightening and computer-controlled flying saw cutting, every module is optimized for operational efficiency. By combining heavy-duty 40Cr quenched and tempered rollers with a high-torque drive system, this production line ensures a continuous, stable workflow that meets the most demanding standards of the metal cutting and forming industry.

Frequently Asked Questions
This line is specifically designed for strip steel with grades Q195 to Q345, with a thickness range of 2.0mm to 5.0mm and a width of 238-279mm.
Accuracy is maintained through a combination of passive leveling, high-precision forming and sizing rollers, and a computer-controlled flying saw for tight length tolerances.
The cage looper acts as a material buffer, storing raw steel strips to decouple the uncoiling process from the forming process, ensuring continuous and uninterrupted production.
Yes, the system includes a dedicated straightening machine with a four-column frame structure to eliminate stress and bending, ensuring the pipe is perfectly straight.
The forming speed ranges from 60 to 80 meters per minute, while the feeding system can operate up to 140 meters per minute.
We use GCr15 for straightening rollers (HRC60-65) and 40Cr quenched and tempered steel for the horizontal and vertical shafts to prevent wear and deformation.
