Customer Reviews

We have been purchase the tube mills from your company since 2007, and i am very happy that the technology is improving.

—— Mr Lim

we brought 4 mills at year of 2008, and mills are good, we are now planing to buy another two line

—— R.P.Gutpa

i am working with your company since 2 years ago, your machine quality good, and price is reasonale. Hope cooperation again

—— Mohammad Bagheri

i am from Korea, brought 2 line in 2013, machine not works in good condition, and hope we can work together again.

—— Mr Kim

How to Choose the Right ERW Square Tube Forming Machine?

I. Define Your Production Requirements

1. Tube Size Range

Outer dimensions: Common sizes from 20x20mm to 120x120mm; larger lines available (e.g. 200x200mm).
Wall thickness: From 0.8mm to 6.0mm, depending on application and material.
Length: Standard 6m, custom options like 8m or 12m available.

2. Production Speed / Capacity

Typical speed range: 20–120 m/min
High-speed lines require matching flying cutoff and automatic stackers

3. Material Type

Compatible with low carbon steel (Q235, Q345), galvanized steel, stainless steel
Coil width and thickness must match desired output tube dimensions.

II. Equipment Configuration & Selection Tips

Component	Function	Selection Advice
Uncoiler	Unwinds steel coils	Hydraulic double-head type recommended (10–15 tons)
Leveling / Feeding Unit	Straightens material	Ensures accurate forming, avoids edge waves
Forming & Welding Mill	Tube forming with HF welding	HF welder must match max wall thickness (e.g., 200KW/300KW)
Sizing / Shaping Unit	Defines square/rectangular profile	Crucial for dimensional precision
Flying Saw / Cutoff	Precision cutting to length	Non-contact flying saws are faster & cleaner
Run-out Table / Stacker	Receives and stacks finished tubes	Pneumatic or servo-controlled options available

III. Automation Options (Optional Upgrades)

Servo-controlled mold change for faster size conversion
Online welding seam detector for quality assurance
In-line laser OD & thickness measurement
PLC + Touchscreen + Remote monitoring system

IV. Suitable Application Industries

Structural steel tubing for construction
Furniture frame tubing
Display racks, mechanical enclosures
Solar mounting structures
Automotive chassis & components

V. Key Purchasing Considerations

Material Compatibility (especially for galvanized or high-strength steel)
Ease of mold change & size switching
Weld quality control – critical for export-quality tubes
Spare parts availability and after-sales service
Trial runs or demo video confirmation recommended

VI. Typical Machine Configuration Table

Feature	Standard Type	Reinforced Type	High-Speed Type
Tube Size	20x20–80x80mm	40x40–120x120mm	50x50–150x150mm
Wall Thickness	0.8–3.0mm	1.5–5.0mm	2.0–6.0mm
HF Welder Power	150KW	200KW	300KW
Line Speed	30–60 m/min	40–80 m/min	60–120 m/min
Automation	Manual adjustment	Semi-auto	Full servo automatic
Recommended Use	Furniture / Display	Construction / Scaffolding	Solar & Industrial Tubes
