12inch 325mm ERW Tube Mill

The 12-inch ERW tube mill is an automated high-frequency welding system designed for the production of large-diameter round and shaped steel tubes (such as square and rectangular). This production line is suitable for continuous forming and welding of carbon steel and low-alloy steel strips. It is widely used in oil and gas pipelines, structural tubing, pressure pipelines, bridge foundation piling, and other applications, meeting the global demand for high-quality, medium-thick wall welded pipes.

List of Equipment Supply

No.	Equipment Name	Function Description
1	Hydraulic Coil Car + Double-Cone Uncoiler	Fast coil loading and automatic decoiling with tension control, supports heavy coils.
2	Shear & Butt Welder	Connects two steel strips via automatic shearing and welding to ensure uninterrupted production.
3	Accumulator	Stores steel strip during coil changes to avoid line stoppage and maintain continuity.
4	Forming Mill (Roughing + Finishing)	Gradually bends the flat strip into a round tube; roughing pre-forms, finishing refines.
5	HF Induction Welder + Cooling System	Induction heating and welding of strip edges; water cooling protects equipment and product.
6	Inner & Outer Burr Removers	Removes welding flash to improve pipe appearance and internal smoothness.
7	Sizing & Straightening Section (with Round-to-Square)	Adjusts pipe dimensions, supports square and rectangular tube production.
8	Flying Saw Cutting System	Cuts pipes at preset lengths; supports hot saw, cold saw, or milling cutter.
9	Output Conveyor + Stacker	Automatically aligns, stacks, and discharges finished pipes for further processing.
10	Centralized Electrical Control (PLC+HMI)	Controls the entire line, supports one-button start, fault alarms, and data records.

Sizing section and Turkey section usage

Sub-unit	Function
Sizing Mill	Multiple roll stands for radial shaping and sizing with quick-adjust design.
Round-to-Square Unit	Converts round tubes into square/rectangular ones by changing only sizing rolls.
Straightening Device	Corrects axial distortion caused by welding/forming to improve straightness and ovality.
Surface Polishing Unit	Light pressing/polishing rolls improve appearance, suitable for decorative/furniture-grade tubes.
Independent Drive System	Each stand is driven by variable frequency motors for segmental speed control and easy upgrades.

Advantages:

Dimensional accuracy within ±0.5mm
Fast mold change and format switching
Improved product straightness and form
Compatible with downstream processes like coating, galvanizing, perforation
Suitable for structural, mechanical, construction, transport, and furniture applications

Finishing Auxiliary Equipment Description

Equipment Name	Function Description
Pipe Straightening Machine	Corrects bending, waves, or twisting formed during welding or cooling using 6 or 7 rollers with adjustable pressure.
Hydrostatic Tester	Injects pressurized water (up to 23MPa) into the pipe to test for leaks or burst defects.
Pipe End-Facing (Milling) Machine	Mills pipe ends flat and burr-free for flange connection or girth welding; includes automatic clamping and dual-head milling.
Eddy Current Tester	Non-destructive inspection using eddy current sensors to detect surface or near-surface defects, especially in welds.
Automatic Pipe Bundling Machine	Automatically aligns, counts, bundles, and wraps finished pipes. Often includes lifting table, steel strapping, and film wrapping systems.

Operating Procedure

Selection Advice for Customers

- For export or high-end pipe markets, it's recommended to include hydrostatic testing and eddy current inspection systems.
- For pipe end processing requirements, add the end-facer for precision preparation.
- Straighteners and bundlers are standard for large-diameter lines and improve finishing automation.
- All machines can be integrated into a centralized control system for digital traceability and smart management.
