What is the Advantage of DFT Technology (Direct Form to Square Tube)?

The primary advantage of DFT is its ability to directly form square or rectangular tubes from flat strips, bypassing traditional round-to-square forming stages. This innovation reduces tool wear, enhances surface quality, and accommodates a broader range of sizes and thicknesses, making it a preferred choice in high-demand sectors.

Direct Square Tube Mill Line

Automatic Size Change, Direct Square Welded Pipe Line. This production line is equipped with high-frequency welding equipment for producing square rectangular and irregular pipes. The raw material used in this production line is strip steel after longitudinal cutting.

The strip steel passes through an uncoiler, straightening, leveling, and shear welding machine before entering the looper storage device. It is formed and bent to the required shape and size, then welded, deburred, cooled, sized, and cut into the required size pipe by a flying saw. It is then transported to the packaging rack through a roller conveyor for packaging and becoming a finished product.

Direct Forming Mill To Square Pipe

This unit adopts internationally advanced forming technology and electric adjustment methods and is the new generation product of China’s direct square tube production line. The unit adopts electric adjustment, and one set of rollers produces products of different specifications without changing the rollers. Only electric adjustment is needed, greatly saving roller-changing time and reducing the labor intensity of workers.

Adjusting products of different specifications takes about 2 hours, making it suitable for production modes of multiple varieties and small batches.The entire unit adopts a PLC control system. The control of the DC motor adopts a digital speed regulation system, which has high accuracy and stable performance. The electrical control automation of the entire line is high, easy to operate, and easy to maintain.

Direct Square Forming Production Line Workflow

Uncoiling: Metal coils are loaded and fed into the machine.
Leveling and Feeding: Coil is straightened and fed smoothly.
Forming: Coils are directly formed into square or rectangular shapes using roll forming techniques.
Welding: High-frequency induction (HFI) welding joins the edges.
Sizing and Straightening: Ensures perfect dimensions and reduces deformations.
Cutting: Pipes are cut to required lengths using a cold saw or flying shear.
Inspection and Packing: Pipes undergo quality checks and are packed for shipment.

Advantages of Direct Forming

Material Savings: Direct forming reduces scrap and material usage, especially at corners.
Improved Dimensional Accuracy: Eliminates distortion caused by reshaping round pipes.
Reduced Tooling Costs: Fewer roll changes for different pipe sizes.
Energy Efficiency: Lower energy consumption compared to traditional methods.
Wide Range of Applications: Suitable for construction, automotive, furniture, and energy industries.

FAQ:

1. How does DFT differ from traditional tube mill forming?

Traditional tube mills require roller changes for each tube size, while DFT adjusts the forming section automatically, reducing downtime, tooling changes, and production waste.

2.What materials can be processed with DFT?

DFT can handle carbon steel, galvanized steel, stainless steel, and high-strength steel, depending on the application requirements.

3.Which industries benefit from DFT?

Industries requiring multiple tube dimensions — such as construction, furniture, automotive, and mechanical structure manufacturing — often choose DFT for flexible production.

4.Can DFT produce both round and square tubes?

Yes. DFT can form round, square, and rectangular tubes on the same line with quick size adjustments and no roll changing.
