Product Overview
The Welded Pipe Production Line is a high-precision industrial solution engineered for the seamless manufacture of high-quality steel pipes. Utilizing advanced cold-forming technology, this system transforms strip steel (Q195-Q345) into precise tubular profiles, integrating uncoiling, forming, welding, sizing, and cutting into one synchronized workflow to maximize operational efficiency.
Designed for versatility and durability, the line features a robust structural frame and high-performance components, including a computer-controlled flying saw and a specialized straightening machine. This ensures that every pipe produced meets stringent length accuracy and straightness standards, making it ideal for demanding applications in the metal tools and machinery equipment sectors.
