11. What equipment is needed for the production of high-frequency welded steel pipes?

(1) Uncoiler: Used to unfold the crimped metal strip (such as steel strip) into a straight state in preparation for subsequent processing.
(2) Strip leveling machine: Level the uncoiled strip to eliminate the bending and wavy shape of the strip during the winding process and ensure the flatness of the strip.
(3) Shear butt welding machine: Perform precise shearing on the strip and butt weld multiple strip sections as needed to meet the requirements of production continuity.
(4) Material cage/storage loop: used to store a certain amount of strip to ensure the continuous feeding of the production line, and to smoothly release the strip to the next process when needed.
(5) Forming machine: Through multiple passes of rolling and forming molds, the strip is gradually deformed into the required tube shape (such as round pipe, square pipe, etc.).
(6) High-frequency welding machine: High-frequency induction heating technology is used to weld the formed pipe blanks. The high-frequency current passes through the edge of the billet to quickly heat it to a melted state, and the weld joint is achieved by the action of the extrusion roller.
(7) Sizing machine: Perform precise sizing treatment on the welded pipe, and adjust the diameter and wall thickness of the pipe through extrusion rollers to meet product specifications.
(8) Flaw detection equipment: Non-destructive flaw testing of welded pipes, such as ultrasonic flaw detection, X-ray flaw detection, etc., to find and eliminate welding defects.
(9) Flying saw shearing machine: According to the order requirements, the sized pipe is cut according to the specified length to form the final steel pipe product.
(10) Other auxiliary equipment: such as steel pipe straightening machines, pipe section processing equipment, hydrostatic testing machines, etc., are used for further processing and testing of steel pipes to ensure that their quality and performance meet the standard requirements.
