ERW Tube Mill Lines: HG20-HG610
The ERW20 series high frequency welded pipe unit adopts the roller forming principle to continuously produce straight seam welded pipes. It adopts high frequency induction welding and can produce not only round pipes, but also square and rectangular pipes and special-shaped pipes that do not exceed the processing range of round pipes.
The ERW Tube Mill Line is a continuous, automated industrial system used to produce Electric Resistance Welded (ERW) steel tubes and pipes. The line forms steel strip into a tubular shape and joins the edges using High-Frequency Induction Welding (HFIW) technology. This process ensures efficient, precise, and high-speed tube production, capable of manufacturing round, square, rectangular, and special-shaped tubes within the forming range.
This equipment is supplied by Great Wall.

The FFX Tube Mill incorporates the internationally advanced FFX forming process, which offers a range of advantages including stable forming, excellent surface quality of steel tubes, and easy to change specifications. This FFX forming machine is divided into two sections: rough forming and fine forming. The rolls in the rough forming section can accommodate various specifications of steel tubes, reducing the number of rolls required by 30% to 60% compared to conventional roll forming units. This not only saves on roll inventory but also minimizes roll changeover and adjustment time, significantly enhancing production efficiency. Additionally, the use of segmented rolls instead of integral rolls reduces the need for spare parts storage.
The FFX (Flexible Forming and expanding) pipe making machine is an advanced tube forming system that utilizes a single set of universal forming rolls to produce different pipe sizes without roll changing. industrial pipe making machine significantly improves production efficiency, reduces downtime, and enhances dimensional accuracy.
The FFX tube mill uses adjustable common rolls in the breakdown forming section. Instead of replacing a complete roll set for each pipe diameter, operators select the required specification through the PLC, and the roll positions are automatically adjusted. Fin-pass and sizing rolls may still require adjustment or quick replacement.
Uncoiling & Shearing
Steel coils are uncoiled and cut into strips with the required width.
Strip Entry & Welding Preparation
The strip passes through a shear and end welder, then enters the accumulator or loop bridge for continuous feeding.
Flexible Forming (FFX System)
The strip is gradually formed into a round tube by universal shared rolls, not fixed per size.
Roll stands automatically adjust position via servo motors or hydraulic controls to match the desired pipe diameter.
High-Frequency Welding (ERW)
The edges of the formed tube are heated by high-frequency induction and pressed together to form a solid longitudinal weld seam.
Weld Seam Scarfing & Cooling
Internal and external weld beads are removed. The tube is then air or water cooled.
Sizing and Straightening
The tube enters a series of sizing stands to achieve final outer diameter and roundness. Straightening follows.
Cutting to Length
A flying saw or cold saw cuts the pipe to the required length without stopping the line.
Output & Stacking
Finished pipes are conveyed to a run-out table and bundled for packaging.
FFX technology significantly reduces specification changeover time. Breakdown roll positioning can typically be completed within 15–30 minutes, while a complete size change may take approximately 1–2 hours, depending on the tube size, wall thickness and line configuration.
| Changeover Activity | Conventional Tube Mill | FFX Tube Mill |
|---|---|---|
| Breakdown roll replacement | Normally required | Generally not required within the shared range |
| Breakdown stand positioning | Manual setup and adjustment | Recipe-based automatic or remote adjustment |
| Fin-pass and sizing adjustment | Required | Required or completed using quick-change units |
| Trial material consumption | Generally higher | Reduced through stored process parameters |
| Complete changeover time | Depends heavily on roll replacement | Usually significantly shorter |
| Dependence on operator experience | High | Reduced through PLC recipe control |
Shared forming rolls can reduce the required number of roll sets by approximately 30%–60%. This lowers tooling purchasing, storage, maintenance and roll-handling costs, especially for factories producing multiple pipe sizes.
PLC-controlled roll positioning and stored production recipes improve repeatability between production batches. The system helps maintain stable pipe diameter, roundness, weld seam position and forming consistency while reducing manual adjustment errors.
| Feature | Description |
|---|---|
| No Roll Change Required | A single roll set forms multiple pipe sizes, minimizing downtime. |
| CNC Servo Adjustment | Fully automatic, recipe-based setup for fast size changes. |
| High Dimensional Accuracy | Consistent forming force and better roundness control. |
| Material Savings | Reduced strip edge trimming and improved yield. |
| High-Speed Production | Up to 120m/min depending on pipe size and model. |
Direct Square Forming Tube Mill: LW120-LW2000
Cold bending profile steel and square/rectangular pipe line is the equipment used for production of open-mouthed and close-mouthed profile steel. With combined type of rollers, and multi points pre-bending forming technology, rollers can be changed quickly with no necessary to remove main axis or stands. Further, with the low loading, it can reduce 80% of rollers cost and 90% of time for changing rollers. All specified open or close mouthed profile steel can be produced with one set of combined rollers. lt is suitable for multi-specification small batch production and meet the market requirement as well.
Great Wall is a professional square tube mill line supplier specializing in direct square forming tube mills for square and rectangular steel tube production. Our DFT tube mill lines use combined roll tooling and multi-point pre-bending technology to support multiple tube sizes with reduced tooling costs and faster size changeover.
DFT tube mill is an industrial production line used to manufacture square or rectangular steel pipes directly from steel strips through continuous roll forming, high-frequency welding, sizing, and straightening processes. Compared to traditional round-to-square forming, direct square forming improves precision and material utilization. As a professional Direct Forming Tube Mill manufacturer, Great Wall offers a complete range of high-performance tube mill equipment for square and rectangular tubes.
The process begins with steel coil uncoiling, followed by leveling and shearing. The strip is then fed into the forming section where rolls progressively shape it into square or rectangular forms. High-frequency induction welding bonds the edges, after which the welded tube undergoes sizing, straightening, cutting, and stacking. Great Wall’s square tube mill lines feature solid-state HF welding, CNC control systems, and automatic adjustment modules to ensure stability and consistency across production runs.
The direct square forming tube mill can process a wide range of steel coils for manufacturing square and rectangular tubes. The forming system can be configured according to material strength, strip thickness, finished tube size and required production speed.
