FX165, FX219 & FX273
ERW Tube Mill Lines
FX165, FX219 and FX273 share one XFX listing but have separate round and square ranges, wall thicknesses, motor notations, HF welder values and listed speeds. Compare each model with your exact tube sizes and matching wall thicknesses before discussing a project configuration.
You can start with the specifications you already have. Final line selection needs a size-by-size review.
01 / THE LINE FAMILY
Three model labels. One project-specific discussion.
FX165, FX219 and FX273 share one XFX English product listing, with a separate technical column for each model. Review the three sections below, then send your complete tube schedule for a project-specific discussion.
An ERW line forms steel strip into tube, joins the longitudinal seam with high-frequency welding, sizes the section and cuts finished lengths. The appropriate equipment and tooling depend on your actual tube list, material and output target.

The saved XFX English product page lists these models in separate columns. Pair each planned tube size with its wall thickness; confirm line suitability and equipment scope in the project proposal.

The saved model table does not provide a model-specific rectangular-tube range. Send exact rectangular sections and paired wall thicknesses for review. A listed size and thickness range does not establish that every pairing is feasible. Listed speed is a reference from the existing XFX listing and is not a guarantee for every tube size, wall thickness or material combination. Final operating parameters are confirmed for the project. Main-motor notations are reproduced from the existing XFX listing without converting power or interpreting the drive configuration.
03 / PRODUCTION REQUIREMENTS
Start with the tubes you need to make.
Round, square and rectangular tube projects may need different tooling and sizing arrangements. For each planned tube, pair the exact outside diameter or section size with its wall thickness. A broad size range on its own is not enough for final line selection.
You can contact us before every detail is settled. Tell us what is known now; we can identify what the technical proposal still needs.
Send your initial requirementsYour first tube schedule
- Tube shape and each exact round, square or rectangular size
- Matching wall thickness for every size
- Steel material or grade, if known
- Required production speed or capacity, if known
- Coil or strip dimensions and coil weight, if known
- Local electrical supply and available workshop space, if known
- Destination country and finished tube length
- Cutting requirement, if known
Even a partial schedule is useful for the first discussion.
04 / PRODUCTION PROCESS
From steel strip to finished tube
A typical ERW route provides a way to discuss the line. Its exact stations and equipment scope are confirmed in the project proposal.
01Coil entryUncoiling and strip preparation
02Strip continuityJoining and accumulation where required
03Form & weldForming stands and HF seam welding
04Size & cutSizing, cutting and run-out handling
Additional seam treatment, cooling, packing and inspection needs should be specified for the project; this diagram is not a fixed bill of materials.
05 / EQUIPMENT SCOPE
Know what to review in the quotation.
The same product schedule can lead to different equipment choices. Confirm what is included, excluded or separately quoted before comparing offers.
Coil entry & accumulator
Review coil handling, strip joining and how the line maintains strip supply during production.
Forming, HF welding & sizing
Discuss the section mix, welding configuration, sizing method and controls for the required tube list.
Cutting & handling
Confirm finished lengths, end-quality expectations and the cutting and run-out arrangement.
Roll tooling & spares
Agree which sizes need tooling, how size changes will be handled and what spare-parts scope the project needs.
A cold saw, hot friction saw, accumulator type, uncoiler arrangement, packing equipment and tooling set are project decisions. No item above is promised as standard or free.
06 / TOOLING & SIZE CHANGES
Plan the whole tube schedule, not just one size.
Each tube shape and size change can affect roll tooling and setup. Share the sizes you expect to make most often and any future sizes that matter to your investment. XFX can then discuss a tooling plan with the line configuration.
Changeover time and the number of tooling sets are not assumed on this page; they belong in a project-specific technical proposal.
07 / FACTORY & SUPPORT
Work with the team behind the equipment.
XFX has its own factory in China. We can provide on-site installation and commissioning, operator training, remote technical support, operation and maintenance documents, and spare-parts support.
The project's service scope is confirmed in its proposal. The customer is responsible for installation personnel's visas, flights, meals, accommodation and wages during the installation period.

08 / BUYER QUESTIONS
Questions before choosing FX165, FX219 or FX273
How do I compare FX165, FX219 and FX273?
Compare the separately listed round and square ranges, wall thicknesses, main-motor notations and HF welder values above. Ask XFX to review every planned tube size, matching wall thickness and material before confirming a line and tooling.
Can I ask for a quote before all my specifications are ready?
Yes. Start with what you know. For final line selection, each planned tube size should be matched with its wall thickness; material, output and cut length also help define the proposal.
Does the line include a saw, tooling and packing equipment?
The quotation should state the included equipment and any separately quoted options. Cutting method, tooling sets and packing arrangements are selected for the project, so do not assume a fixed package from a model name.
Can we discuss square or rectangular tubes?
Yes. Send the exact section sizes and matching wall thicknesses. XFX can review the required forming, sizing and tooling arrangement before confirming feasibility for a particular model.
What support can XFX provide?
XFX can provide on-site installation and commissioning, training, remote technical support, operation and maintenance documents, and spare-parts support. Project details and the customer's installation-related costs are confirmed in the proposal.
