AIS MACHINERY's robotic steel tube stacking machine provides a flexible, efficient solution for automatic steel pipe stacking and bundling. An advanced alternative to fork-type and electromagnetic stacking systems, it offers smooth handling, a space-saving layout, simplified maintenance, and easy integration with automatic strapping machines for complete steel tube packing lines.

Direct square forming (also known as direct forming to square or rectangular tube) is a tube mill process in which flat steel strip is directly formed into square or rectangular shapes without first forming into a round pipe. The entire shaping takes place in the form-and-size section, enabling a more efficient, accurate, and material-saving production for hollow structural sections (HSS).

High-Efficiency Coil Slitting Solution for Multi-Width Steel Processing

A Heavy Duty Slitting Line with Quick Change Double Slitting Unit is designed to process steel coils into multiple strip widths required for downstream manufacturing operations. It is widely used in steel service centers, tube mills, roll forming plants, stamping facilities, automotive component production, and other coil processing industries.

32mm ERW Tube Mill Machine for producing round, square and rectangular steel tubes. Low investment, high speed, compact design, 100kW HF welder and flying cold saw. Ideal for startups and tube manufacturers.

This production line utilizes high-frequency induction welding. Steel strips are continuously fed through forming rollers to gradually shape into a round tube. The strip edges are heated by high-frequency current and pressed together by squeeze rollers to form a solid weld seam. The entire process is automated, ensuring high efficiency, precision, and operational stability.

Pipe diameter 25mm to 114mm, Pipe thickness range 1.5mm to 5.0mm

The strip is continuously fed into a series of rollers that gradually bend it into a round shape. High-frequency induction heating melts the edges, and they are pressed together to form a strong, seamless weld. The pipe is then shaped into the required profile (round, square, or rectangular), straightened, and cut to length.

Pipe diameter 21.3mm to 76.2mm, Pipe thickness range 1.0mm to 4.0mm

Cored wire tubes are manufactured using cold-rolled low carbon steel strips, filled with single or composite functional powders such as calcium, aluminum, silicon, and titanium. By precisely controlling the feeding rate and insertion depth, the core material is released into molten steel, where it reacts with impurity elements like oxygen (O) and sulfur (S), forming stable compounds (e.g., CaO, CaS). This reaction effectively modifies inclusions and purifies the steel.

The production of cored wire tubes is a high-precision, high-efficiency cold roll forming process. The core challenge lies in ensuring uniform filling, consistent sealing, and continuous stable operation. The entire process integrates automated machinery with advanced control systems to meet the strict requirements of metallurgical refining.
