HF WELDING & IMPEDER SPARES

Magnetic Bars for HF Welded Tube Mills

Replacing magnetic bars in an XFX tube mill or another existing HF welding line? Send the installed part's photos and dimensions, plus your impeder, welder and tube-production details. XFX can review the requirement before supply is confirmed.

A welder power rating, mill model or tube diameter alone cannot identify a replacement bar. The actual HF welding arrangement must be checked.

01 / PRODUCT ROLE

A ferrite magnetic bar for the impeder area.

XFX describes ferrite magnetic bars for impeder systems in the HF welding section of ERW tube mills. They are a related welding component and a possible replacement spare, with material and size selected for the actual tube and impeder setup.

“Magnetic Bars” is the product name on this page. “Ferrite” describes the material named by the XFX listing; an impeder is the assembly or arrangement in which the bars may be used. Those terms are related but do not mean that every impeder uses one fixed bar.

02 / HF WELDING RELATIONSHIP

Review the bar with the coil and welding setup.

The XFX sources link the HF welder, induction coil and impeder/ferrite arrangement. This is a discussion map, not a fixed electrical design or bundled supply list.

The primary XFX detail associates ferrite bars with the impeder system and says selection depends on tube size, wall thickness, welding speed, impeder structure, cooling condition and HF welder setup. It does not say every induction coil requires this exact bar.

03 / XFX PRODUCT INFORMATION

Ferrite is identified; a grade is not.

XFX identifies these as ferrite magnetic bars used in relevant HF welding impeder systems. The product detail does not list a universal size, specific ferrite grade or rated magnetic properties.

WHERE USED

HF welding impeder system

Discuss the bar within the installed impeder and welding-section arrangement.

MATERIAL WORDING

Ferrite magnetic bars

Ferrite is named by XFX. Confirm the actual material grade and specification for a proposed replacement.

SELECTION BASIS

Actual machine and tube list

Review tube products, welding conditions, impeder structure and the part itself before confirming the proposed replacement.

The gallery photo shows multiple bar shapes. It is a product-family image, not a dimensional drawing or assurance that any pictured shape fits your system.

04 / REPLACEMENT COMPATIBILITY

Fit depends on dimensions and the installed arrangement.

Neither HF welder power nor tube size alone establishes the right bar. Send the old part's shape and measurements with your impeder and production information.

PART ITSELF

Shape and dimensions

Photos, markings if any, cross-section or diameter, length, an existing drawing or sample help identify what is installed.

INSTALLATION

Impeder and cooling

Describe the assembly, mounting position and cooling method if known. Final interface requirements are checked for the project.

PRODUCTION

Tube and welder data

Pair each tube size with its wall thickness. Include material, welding speed and welder brand/model/power if available.

A cracked, worn or missing bar can prompt an enquiry, but a photograph does not establish the cause of a welding problem. The coil, impeder arrangement, setup, tube specification and machine condition may also need review.

05 / REPLACEMENT CHECKLIST

What should you send for magnetic bar replacement?

Start with what is available. XFX can identify any further measurements needed after reviewing the existing setup.

  1. Part photosOverall view and close views showing shape, ends, markings and any damage.
  2. DimensionsOverall length and cross-section or diameter if measured; include the shape and any drawing. No universal required dimension is asserted here.
  3. Existing impederPhotos and installation arrangement, plus cooling information if known.
  4. Tube and processEach tube shape and exact size paired with wall thickness; material and welding speed if known.
  5. Machine and welderTube mill model and HF welder brand, model and power if available; induction-coil information if relevant.
  6. Quantity and sampleRequired number of bars, replacement or spare purpose, and whether an old sample can be provided.

Send photos or drawings by WhatsApp or email. The page's text form does not upload files.

06 / THREE BUYER ROUTES

Describe your installed equipment or planned project.

XFX equipment replacement

Send the original mill or welder model if known, old bar photos and measurements, impeder arrangement, each tube size with matching thickness, and the required quantity. A machine model alone is not sufficient.

Discuss an XFX replacement ↗

Other or unknown equipment

Share the current bar, impeder and coil information, welder brand/model/power if known, tube list, drawing or sample availability, installation and cooling details. XFX can discuss the request; compatibility is not assumed.

Send existing-line details ↗

New project spares

Review magnetic bars as a possible item in the HF welding and spare-parts plan. State the proposed line, tube list and desired quantity. Final material, number of bars and supply scope belong in the project quotation.

08 / FACTORY & SUPPORT

Discuss the component in the context of your line.

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.

The service and item scope is confirmed in the proposal. A standalone magnetic-bar order does not automatically include an on-site visit or a full-line service package.

09 / BUYER QUESTIONS

Magnetic bar buying questions

What are magnetic bars used for in HF tube welding?

XFX places ferrite magnetic bars in impeder systems in the ERW tube mill HF welding section. The actual arrangement must be checked.

Are tube mill magnetic bars universal?

No. The bar's size and structure must match the tube specification, impeder design, welding conditions and installed setup.

Is HF welder power enough to identify the part?

No. Send old-part photos and measurements, impeder details and the tube sizes with matching wall thicknesses as well.

Do the induction coil and magnetic bars need review together?

They can be related in the HF welding arrangement. Review both where relevant, but one fixed combination or bundled supply is not assumed.

Can XFX discuss a replacement for another supplier's equipment?

Yes, as an enquiry. The actual part and installed arrangement must be reviewed before fit or supply can be confirmed.

Should I send dimensions, photos or a sample?

All available evidence helps. Send the overall shape, length and cross-section or diameter if measured, plus photos or a drawing; say if a sample is available.

Can magnetic bars be included with new-project spares?

They can be discussed as part of the HF welding spare-parts plan. Final quantity and scope must be set out in the project quotation.

10 / DISCUSS MAGNETIC BARS

Send your bar photos, dimensions and HF welding details.

Tell XFX whether this is an XFX replacement, another existing line or a new-project spare. Include the impeder arrangement, each tube size with matching wall thickness, welder details and required quantity where known. Partial details are enough to start.
