ERW tube mill welding area
The coil is discussed for HF welded tube production and replacement support.
HF WELDING SPARES & REPLACEMENTS
Need a replacement coil for XFX equipment or another existing tube mill? Send the old coil details and your HF welding arrangement. XFX can review the requirement before a coil is specified for supply.
HF welder power alone cannot identify a replacement coil. The existing coil, tube products and installation arrangement need review.

01 / PRODUCT ROLE
XFX describes induction coils as consumable and spare parts for the high-frequency welding section of an ERW tube mill. The coil works with the HF welder in heating the tube edges before welding.
This page covers replacement enquiries and spare-coil planning. It does not establish a universal fit or guarantee that changing a coil will solve a welding problem.
02 / HF WELDING RELATIONSHIP
The sequence is a buyer's orientation, not an electrical design or a fixed supply list.
Coil requirements are also linked to the impeder or ferrite setup and welding speed. These are project-review inputs, not proof of a particular coil design.
03 / EXISTING XFX PRODUCT INFORMATION
XFX describes copper tubing and PTFE protection. Confirm the finished coil design for your project; this page does not provide a universal rated specification.
The coil is discussed for HF welded tube production and replacement support.
XFX identifies these materials. Confirm the grade, conductor size and protection design for the proposed coil.
The final coil design is confirmed before production. Material photos do not determine a finished design.


Request the dimensions, material specification, cooling-water interface and other requirements for the proposed coil. This page does not state a universal coil rating or service life.
04 / REPLACEMENT COMPATIBILITY
A replacement coil must be reviewed against the actual HF welding arrangement before manufacture or supply is confirmed. A machine nameplate or a photograph alone does not establish fit.
Send clear photos, a drawing or sample dimensions where available. Include the installed position and mounting arrangement.
Share the welder brand, model and power if known, plus connection and water-interface information where relevant.
Give each round, square or rectangular tube size with its matching wall thickness, material and planned welding speed if known.
When investigating a welding problem, XFX may need to review the coil alongside the HF welder, related impedance components, setup and operating conditions. This page does not diagnose a fault or promise a repair outcome.
05 / REPLACEMENT CHECKLIST
Send what you have; an incomplete first message is welcome. More precise evidence helps XFX review the actual replacement requirement.
Photos and drawings can be sent by WhatsApp or email. The page's text form does not upload files.
06 / THREE BUYER ROUTES
Provide the original XFX mill or HF welder model if known, tube list with matching thicknesses, old coil photos, dimensions or drawing, installed position and required quantity. A model name alone is not enough to confirm a replacement.
Discuss an XFX replacement ↗Share the other supplier's mill and HF welder details, old coil photos from several angles, dimensions, mounting, connections and water-interface information where relevant. XFX can review the request; fit is not promised in advance.
Send existing-machine details ↗Discuss induction coils with the HF welding configuration and spare-parts plan. Share tube products, expected operating requirements and desired spare quantity. The final supplied quantity and scope belong in the project quotation.
Plan project spares ↗08 / FACTORY & SUPPORT
XFX has its own factory in China. For tube mill projects, XFX can provide on-site installation and commissioning, operator training, remote technical support, operation and maintenance information, and spare-parts support.
Service and item scope are confirmed in the individual proposal. The existence of these services does not imply an on-site visit or included installation for a standalone coil order.

09 / BUYER QUESTIONS
It belongs in the HF welding section, where it works with the welder to heat tube edges before welding.
No. The design must be checked against the tube size, welding position, HF welder and production arrangement.
No. Please also provide the actual coil's photos and dimensions, its installed position and connections, and the tube products.
Yes, as a replacement enquiry. Supply and fit depend on reviewing the actual installed equipment and requirement; compatibility is not promised from the brand or power alone.
A drawing or sample dimensions and clear photos help. Let XFX know if an old coil sample is available; the project team can confirm what is needed.
They can be discussed with the HF welding configuration. The final quantity and scope must be confirmed in the quotation or spare-parts list.
They are related to the welding arrangement. Review them if relevant to your installed setup; they are not automatically included with a coil.
10 / DISCUSS YOUR COIL
Tell us whether this is an XFX replacement, another existing machine, or a new-project spare. Include coil photos or drawing, HF welder details, each tube size with its matching wall thickness and the quantity if known. Partial details are enough to start.
