CARBON & LOW-ALLOY STEEL

High Frequency (ERW) Tube Mills

A high frequency tube mill welds the formed tube seam with a solid-state high frequency welder. ERW (electric resistance welding) is the industry name for the same HF welding process, and the same line is sold as a high frequency tube mill or an ERW tube mill. HF welding delivers stable weld quality at high line speed and is widely used for structural tube, furniture tube and industrial pipe in carbon steel and low-alloy steel.

ERW and HF: one process, two names

The name does not change the machine: whether a buyer asks for a high frequency welded tube mill, a high frequency welding tube mill or an ERW tube mill, the quote comes from the same range. What changes between quotes is the model — 13 models cover Φ8 to Φ219 mm pipe with 0.5 to 8.0 mm wall, and HF power runs from 100 kW on the 25 Mill to 800 kW on the 219 Mill.

Pass design is what makes this a high precision ERW tube mill: YH confirms the forming passes against the pipe size and wall range you send, and builds the frame for stable running and easy maintenance.

The structural steel tube mill duty covers construction pipe, scaffolding and structures, furniture tube, low-pressure fluid pipe and vehicle or trailer tube, in carbon and low-alloy steel.

The same equipment is quoted as an ERW tube mill line or an ERW pipe mill line: uncoiling, forming, welding, sizing and cut-off on one continuous frame, from coil loading through to run-out and packing. A buyer searching for an ERW pipe making machine or an ERW pipe manufacturing machine is describing that same station set, and an automatic ERW tube mill is that line run continuously rather than in manual batches. When you compare China ERW tube mill suppliers, ask ERW tube mill manufacturers for the model, the forming pass design and the welder power rather than price alone. Older datasheets often call the same unit an HF welded tube mill.

Common questions

Is the line fully automatic?
Yes. Coil loading, uncoiling, shear and butt welding, the strip accumulator, feeding and leveling, forming, HF welding, bead removal, cooling, sizing, straightening, cut-off and run-out packing run as one automatic flow, with inspection and storage at the end.
Is an ERW tube mill the same as an HF tube mill?
Yes. ERW is the industry name for the same high frequency welding process. Ask for a high frequency welded tube mill, a high frequency welding tube mill or an ERW tube mill and you get one configuration under either name.
How do I compare the 13 models?
Compare the model that covers your pipe size, the wall range on that model, the HF power quoted for it and the forming pass design behind it. The range is documented in 13 models, from the 25 Mill at Φ8–32 mm to the 219 Mill at Φ114–219 mm, so each one can be checked against your pipe spec before you inquire.
What do I need to send for a quotation?
Four inputs: the pipe standard to meet, the pipe diameter and wall range, the carbon or low-alloy steel grade, and your target line speed and output. YH manufactures in Foshan, China and quotes every HF line from the same 13-model range.
Is an MS tube mill the same machine?
Yes. An MS tube mill, a carbon steel tube mill and the high frequency line on this page are one and the same equipment: MS is the trade shorthand for mill steel — the carbon and low-alloy steel coil this line forms and welds. The quotation comes from the same 13 models under any of these names, configured against the pipe standard and annual output you target.
Is a steel tube making machine a different line from an HF tube mill?
No. Whether a buyer asks for a steel tube making machine, a steel pipe manufacturing machine or a pipe making machine tube mill, it is one station set: uncoiling, forming, welding, sizing and cut-off on one continuous frame, from coil loading through to run-out and packing. A steel tube machine is the same line under its shortest name. The word steel rather than stainless matches the duty of these 13 models — carbon and low-alloy steel coil — with the forming pass design confirmed against your pipe size and wall range.
