The term steel tube mill equipment encompasses the entire suite of machinery that works in concert to produce welded steel tubes from coiled strip . This integrated system comprises several key subsystems, each performing a critical function in the continuous production line. Shijiazhuang Faith Machinery Co., Ltd. specializes in providing complete, synchronized tube mill equipment designed for durability and precision.
A typical line starts with material handling equipment, including a decoller to support the steel coil and a feeding mechanism that guides the strip into the line . This is followed by a strip preparation section, which features a leveling machine to flatten the steel strip and a shear and butt welder to join coil ends for uninterrupted operation . An accumulator (or looper) is a crucial component placed before the forming section; it stores a buffer of strip material, allowing the mill to continue running while new coils are being welded in the entry section .
The core shaping and joining processes occur in the forming and welding stations. The forming section uses a tandem set of rolls to gradually bend the strip into a tube . Immediately after, the welding equipment, such as a solid-state high-frequency welder, fuses the edges together . Following welding, the tube enters the sizing and straightening equipment, which consists of multiple stands of rolls that cold-work the tube to its exact final diameter and shape while improving its straightness .
The downstream finishing equipment includes a flying saw for cutting the tube to length and a run-out table with conveyors for transporting finished pipes . Modern lines often end with an automatic stacking and packing machine to bundle the final product . Throughout the entire process, a centralized control system, typically a Programmable Logic Controller (PLC), monitors and coordinates all operations, ensuring parameter consistency and facilitating quick changeovers for different tube sizes . This comprehensive integration of individual components into a single equipment line by Shijiazhuang Faith Machinery Co., Ltd. enables efficient and high-volume production of steel tubes.
