(1) Uncoiler: Used to unravel the coiled metal strip (such as steel strip) into a flat state, preparing it for subsequent processing.
(2) Strip Steel Leveler: Performs leveling on the uncoiled strip steel to eliminate bends and waves caused during coiling, ensuring the flatness of the strip steel.
(3) Shear Butt Welder: Precisely shears the strip steel and butt-welds multiple strip steel segments as needed to meet the requirements of production continuity.
(4) Looping Pit/Accumulator: Stores a certain amount of strip steel to ensure continuous feeding of the production line and smoothly releases the strip steel to the next process when needed.
(5) Forming Machine: Gradually deforms the strip steel into the desired tube shape (e.g., round, square) through multiple passes of rolling and forming dies.
(6) High-Frequency Welding Machine: Utilizes high-frequency induction heating technology to weld the formed tube blank. High-frequency current passes through the edges of the tube blank, rapidly heating them to a molten state, and welding the joint under the action of squeeze rolls.
(7) Sizing Machine: Conducts precise sizing of the welded tube, adjusting its diameter and wall thickness with squeeze rolls to meet product specifications.
(8) Flaw Detection Equipment: Conducts non-destructive flaw detection tests, such as ultrasonic flaw detection and X-ray flaw detection, on the welded tube to identify and eliminate welding defects.
(9) Flying Shear Cutting Machine: Cuts the sized tube into final steel pipe products of specified lengths according to order requirements.
(10) Other Auxiliary Equipment: Including steel pipe straightening machines, pipe section processing equipment, hydrostatic testing machines, etc., used for further processing and testing of steel pipes to ensure their quality and performance meet standard requirements.
