ERW Tube Mill Line Manufacturer in China
ERW Tube Mill Line for Welded Steel Pipe Production
Zhongyue designs customized ERW tube mill lines for steel pipe manufacturers who need stable forming, high-frequency welding and reliable production flow. As a China ERW pipe mill supplier, Zhongyue plans each welded pipe production line according to pipe OD, wall thickness, material, workshop layout, target output and production requirements.
Product Overview
What Is an ERW Tube Mill Line?
An ERW tube mill line is a welded pipe production line that forms steel strip into pipe and welds the seam with a high-frequency welding system.
Planned around real production requirements
A suitable ERW pipe mill is selected according to pipe OD, wall thickness, material, target capacity, workshop layout, automation level and finished pipe use.
Buyer Decision Guide
What Overseas Buyers Usually Want to Confirm
Most buyers searching for an ERW tube mill line or China ERW pipe mill supplier need clear answers before they ask for a formal quotation.
Can this line cover my pipe range?
The first check is pipe OD, wall thickness, material and pipe length. Zhongyue reviews the product table before recommending the ERW pipe mill model.
What is included in the quotation?
A useful proposal should separate main mill, HF welding system, cutting system, roll tooling, electrical control, auxiliary equipment, spare parts and installation support.
Will it fit my workshop?
Workshop length, crane height, foundation, power supply, coil loading direction and finished pipe handling should be reviewed before the final layout is confirmed.
Who supports installation after shipment?
For overseas buyers, commissioning, operator training, roll adjustment guidance and after-sales communication are part of the real project value.

Complete Equipment Function Table
A complete ERW tube mill line usually includes coil feeding, strip joining, forming, welding, cooling, sizing, cutting, pipe handling and roll tooling.
| Equipment | Function | Why It Matters for Buyers |
|---|---|---|
| Uncoiler | Holds the steel coil and feeds strip into the ERW tube mill line. | Stable coil feeding helps reduce strip tension problems and supports smoother continuous production. |
| Shear and Butt Welder | Cuts coil ends and welds two strip ends together before the next production run. | It reduces downtime during coil changes and helps the welded pipe production line run with fewer interruptions. |
| Accumulator | Stores steel strip temporarily while coil joining or coil change is taking place. | The forming mill can continue running, which is important for production efficiency and output stability. |
| Forming Mill | Gradually forms flat steel strip into an open tube shape before welding. | Good forming design affects pipe shape, weld seam stability, roll life and daily adjustment time. |
| High Frequency Welding System | Welds the tube seam after forming by using high-frequency welding power. | A suitable welding system is key for seam quality, material compatibility and reliable pipe production. |
| Cooling Section | Cools the welded pipe after welding and before final sizing or cutting. | Proper cooling helps stabilize pipe condition and supports more consistent downstream sizing. |
| Sizing Mill | Controls final pipe dimension, roundness or profile accuracy after welding. | Accurate sizing is important for customers who need consistent OD, straightness and finished pipe quality. |
| Flying Saw Cutting Machine | Cuts finished pipe to the required length while the tube mill line keeps running. | The cutting system affects pipe length accuracy, end quality, line speed and downstream handling. |
| Run-out Table | Receives finished pipe after cutting and moves it to collection or packing area. | Good run-out handling reduces pipe damage and helps operators manage finished pipe flow. |
| Tube Mill Rolls & Tooling | Forms, guides and sizes the pipe according to the selected tube range and forming route. | The roll tooling plan directly affects product range, changeover time, forming stability and long-term running cost. |

How to Choose the Right ERW Tube Mill Model
The right ERW tube mill line should be selected according to the pipe product, material, capacity target and factory conditions.
Tube OD
Confirm the minimum and maximum round pipe OD. The OD range is the first reference for mill model, roll size, forming stand design and cutting system selection.
Wall Thickness
Wall thickness affects forming load, welding power, machine strength and line speed. Heavy-wall projects need a stronger configuration than light furniture tube production.
Material
Hot rolled steel, cold rolled steel and galvanized steel may require different forming, welding and surface protection considerations.
Line Speed
Target line speed should be matched with tube size, wall thickness, welding power, cutting method and operator handling capacity.
Application
Construction pipe, scaffolding pipe, furniture tube, greenhouse pipe and structural tube may have different quality expectations, pipe length and inspection requirements.
Workshop Layout
Available workshop length, crane height, raw material flow and finished pipe handling decide how the complete welded pipe production line should be arranged.
Factory Layout Requirements
Before confirming an ERW welded pipe production line, buyers should review the workshop conditions and material flow.
| Workshop length | Confirm total available line length, including coil area, accumulator, forming and welding section, sizing, cutting and run-out table. |
|---|---|
| Crane height | Check crane lifting height and capacity for coil loading, machine installation, roll change and future maintenance. |
| Power supply | Confirm voltage, frequency, transformer capacity and electrical room arrangement before finalizing the welding and drive system. |
| Foundation | Review floor condition and foundation requirements for machine stability, alignment and long-term production accuracy. |
| Raw material flow | Plan how steel coils enter the workshop, where coils are stored and how strips move into the production line. |
| Finished pipe handling | Confirm pipe length, bundling method, storage area and forklift or crane movement after cutting. |
| Operator space | Leave enough working space for line operation, inspection, roll change, maintenance and safe movement around the machines. |

Round-to-Square vs Direct Forming
Square and rectangular tube can be produced through different routes. The right choice depends on product focus, size range and tooling strategy.
| Item | ERW Round-to-Square Route | Direct Forming Square Tube Mill |
|---|---|---|
| Production route | The ERW line forms and welds round pipe first, then uses sizing stands to make square or rectangular tube. | The line forms square or rectangular tube directly according to the designed tube range. |
| Best for | Factories where round pipe is the main product and square or rectangular tube is an additional requirement. | Factories focused on frequent square tube or rectangular tube production and size changes. |
| Tooling plan | Tooling is planned around round forming first and shaped tube sizing afterward. | Tooling can be planned to improve roll sharing and reduce repeated roll changes within the confirmed range. |
| Buyer decision | Choose this route when the project needs a flexible ERW round pipe mill with optional shaped tube production. | Choose direct forming when square and rectangular tube output, changeover efficiency and tooling cost control are the main concerns. |
For projects mainly focused on square and rectangular tube output, review the Direct Forming Square Tube Mill page.
