Welding Square Tube Roll Forming Machine for Steel Pipe Tube Production

In the fields of building steel structures, machinery manufacturing, furniture, automobiles, fitness equipment, shelves, guardrails, air conditioning refrigeration, decorative pipes, etc., square and rectangular pipes are indispensable basic materials. Traditional welded pipe production lines often face problems such as slow speed, difficulty in changing types, unstable weld quality, poor sizing accuracy, and high dependence on manual labor. Our Welding Square Tube Roll Forming Machine for Steel Pipe Tube Production integrates unwinding, leveling, shear welding, storage, forming, welding, deburring, cooling, sizing, straightening, flying saw cutting, and automatic stacking, designed for efficient, precise, and continuous steel pipe production.

working flow：

Uncoiler → Leveling machine → Shear welding → Storage ring → Forming host → High frequency welding/argon arc welding → External burr scraping → Internal burr removal → Cooling → Diameter straightening → Flying saw cutting to length → Automatic stacking

The above modules can be flexibly selected according to customer production capacity, pipe specifications, and automation needs.

Why choose our welded square tube cold bending production line?

We not only provide equipment, but also offer complete steel pipe production solutions. From process analysis, section optimization, roll mold development, sample trial production, to installation and debugging, operation training, and after-sales support, we accompany you throughout the entire process. Each device undergoes strict testing before leaving the factory to ensure rapid production and stable operation upon arrival at the customer's site.

Core advantages: High speed welding, precise molding

1.High speed continuous production significantly increases production capacity
By adopting optimized roller flower design, servo/variable frequency drive and high-speed transmission structure, the typical production speed can reach 20-80 m/min, depending on the pipe diameter, wall thickness, material, welding method and configuration. The entire line runs continuously, suitable for large quantities and multi specification steel pipe orders.

2.High precision forming and firm welding seam
Multi pass precision roll bending forming, combined with high-frequency welding, argon arc welding or plasma welding optional, to ensure that the weld seam is firm and the inner and outer surfaces are flat. External burr scraping and internal burr removal devices improve the internal and external quality of square and rectangular pipes.

3.Square rectangular tube sizing and straightening, stable size
After welding, through sizing, straightening, and shaping, the square tube has good right angles, high straightness, and small twisting, with consistent cross-sectional dimensions, meeting high assembly requirements. It can produce square tubes, rectangular tubes, and round tubes, achieving multi functionality with one machine.
4.Accurate cut to length, flat end face
PLC control combined with servo feeding and high-precision encoder ensures accurate cutting length of flying saw/fixed length cutting, smooth and burr free end face, reducing on-site secondary processing and material waste.

5.Intelligent automatic control, user-friendly operation
The entire line is controlled by PLC and touch screen, with interfaces for parameter storage, formula calling, fault alarm, production statistics, and remote technical support. Operators can quickly get started after training, reducing reliance on skilled workers.

6.One machine with multiple specifications, quick changeover
By using quick change rollers, molds, and formula storage, steel pipes with different diameters, wall thicknesses, lengths, and square ratios can be produced. By calling parameters on the touch screen, orders can be switched, suitable for multi variety, batch, and flexible production.

Common problem:

Q1: What specifications can this welded square tube production line produce?
A: We can produce square tubes, rectangular tubes, and round tubes, with a typical square tube range of 10 × 10-150 × 150 mm and a thickness of 0.5-4.0 mm. Specific customization is available upon request.

Q2: What are the welding methods available?
A: High frequency welding is commonly used for carbon steel and galvanized steel; Stainless steel can be welded using argon arc welding or plasma welding to ensure the quality and surface effect of the weld seam.

Q3: How fast is the production speed?
A: The typical speed is 20-80 m/min, depending on the pipe diameter, wall thickness, material, welding method, and cutting configuration. Higher speed solutions can be customized as needed.

Q4: How to ensure the accuracy of fixed length cutting?
A: Adopting PLC control, servo feeding and high-precision encoder, combined with flying saw/fixed length cutting, the length consistency is good and the end face is flat.

Q5: Does it support automatic stacking and connected production?
A: Support. Optional automatic stacking, conveyor line, and upper computer management system to achieve continuous production with fewer people.
