(1) Uncoiler: Used to unwind curled metal strips (such as steel strips) into a flat state, preparing them for subsequent processing.
(2) Steel Strip Leveler: Levels the steel strip after uncoiling, eliminating bends and waves caused during the coiling process to ensure the flatness of the strip.
(3) Shear and Butt Welder: Precisely shears the steel strip and, if necessary, butt-welds multiple strip segments together to meet the requirements of continuous production.
(4) Material Cage/Accumulator: Used to store a certain amount of steel strip to ensure 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 roller pressing and forming dies, gradually deforms the steel strip into the desired tube shape (such as round or square tubes).
(6) High-Frequency Welding Machine: Utilizes high-frequency induction heating technology to weld the formed tube blanks. High-frequency current passes through the edges of the tube blanks, rapidly heating them to a molten state and achieving welding bonding under the action of squeeze rollers.
(7) Sizing Mill: Precisely sizes the welded tubes by adjusting their diameter and wall thickness through squeeze rollers to meet product specifications.
(8) Non-Destructive Testing Equipment: Conducts non-destructive testing on the welded tubes, such as ultrasonic testing and X-ray testing, to detect and eliminate welding defects.
(9) Flying Saw: Cuts the sized tubes to specified lengths according to order requirements, forming the final steel pipe products.
(10) Other Auxiliary Equipment: Such as steel pipe straighteners, tube section processing equipment, and hydrostatic testing machines, used for further processing and testing of steel pipes to ensure their quality and performance meet standard requirements.
