We are a professional manufacturer specializing in roll profile high-frequency welded pipe equipment, including four roller cold rolling mills, high-speed shear equipment, precision cold forming equipment, stainless steel welded pipe equipment, and various complex cross-section solutions. As one of China's earliest specialized manufacturers of welded pipe equipment, we bring decades of expertise to every project.

Our forming and sizing unit utilizes a combination of FF forming and FFX forming techniques to produce steel pipes through HF induction welding. The heating method employs either HF induction or contact welding, where steel pipe fed into the mill is formed into pipe profile by forming rolls.

Through the skin effect and proximity effect of high frequency current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe to rapidly heat it to welding temperature. Pressure welding is completed when pipe fringes are squeezed together by squeezing rolls. After normalizing, cooling, sizing and primary straightening, steel pipes of desired dimensions are produced.

• Application: Our HF (ERW) welded pipe forming machine produces building materials pipes widely used for construction materials, drainage, and energy supply systems.
• Custom Sizes: Carbon steel pipe diameter can be customized from 25-606mm with wall thickness 0.5-25mm for various applications.
• Material Width: Machines can be customized to accommodate steel strip widths from 100mm to 1000mm, with designs available to meet specific requirements.
• Support Services: We provide comprehensive operation manuals and video tutorials with each machine, along with free training at our facility. On-site installation and training by our technicians is available (relevant costs to be covered by client).
