Category Connection: Steel Pipe Production Line
Brief: In this video, we take you on a detailed walkthrough of the Galvanized ERW Steel Pipe Production Line. You'll see how this advanced system manufactures both round and square pipes from steel coil, using high-frequency welding and precision forming. Learn how this solution can streamline typical workflows and improve reliability for producing pipes with diameters from Φ114mm to Φ273mm and thicknesses up to 10mm.
Related Product Features:
  • Produces both round pipes (Φ114mm-Φ273mm) and square pipes (15×15-60×60mm) from HRC, CRC, or galvanized steel coil.
  • Utilizes high-frequency welding for strong, reliable seams at speeds ranging from 30 to 120 meters per minute.
  • Features high precision with minimal tolerances, such as frame vertical degree ≤0.05 and diameter roundness error ≤0.08mm.
  • Includes both cold saw and friction saw cutting options for efficient on-stream cutting of endless tubes into measured lengths.
  • Designed for stability and speed, ensuring consistent output quality across various pipe dimensions and thicknesses.
  • Customizable machine design to meet specific customer requirements and production needs.
  • Comprehensive production process from uncoiling, forming, welding, sizing, straightening, to final cutting.
  • Suitable for a range of materials including low carbon steel, low alloy steel, galvanized steel, and stainless steel.
Faqs:
  • What types of pipes can this production line manufacture?
    This line is designed to manufacture both round pipes, with diameters from Φ114mm to Φ273mm and thicknesses from 4.0mm to 10mm, and square pipes, with sizes from 15×15mm to 60×60mm and thicknesses from 1.5mm to 2.0mm.
  • What welding technology is used, and what are the production speeds?
    The line uses a solid-state high-frequency welder for longitudinal seam welding. Production speeds are adjustable, typically ranging from 30 to 120 meters per minute, depending on the pipe specifications and model.
  • Can the machine be customized for specific production requirements?
    Yes, the machine design can be customized as per customer requirements, including adjustments for specific pipe dimensions, materials, and integration into existing workflows.
  • What materials can be processed with this ERW tube mill?
    The line can process a variety of raw materials, including hot-rolled coil (HRC), cold-rolled coil (CRC), galvanized steel, as well as low carbon steel, low alloy steel, and stainless steel.
