GI pipe weld-seam area
Applied after ERW welding where a galvanized tube project calls for zinc material at the seam.
GI PIPE WELD-SEAM TREATMENT
Zinc Spraying Machine for ERW Tube Mill Projects
Discuss zinc spraying at the welded seam area of galvanized tube after ERW welding. XFX can review equipment for a new line, a separate machine purchase, or an existing-line replacement or upgrade.
Not every GI tube mill needs the same zinc-treatment arrangement. Suitability depends on the material, welding and seam-treatment process, tube products, line speed and project layout.
01 / PRODUCT ROLE
Treat the weld-seam area of galvanized tube.
The saved XFX detail page describes a zinc spraying machine, also called electric arc spraying equipment, for applying zinc material to the weld-seam area after ERW welding in relevant GI pipe production.
The scope is local seam treatment. This page does not describe hot-dip galvanizing, full-pipe coating or a guaranteed corrosion result. The required treatment and acceptance criteria belong in the project discussion.
02 / PROCESS RELATIONSHIP
Review the spraying step with the welding section.
XFX places zinc spraying in the discussion of post-weld seam treatment. The actual installation position and equipment interfaces depend on the line design; the sequence below is conceptual, not a fixed layout or included supply list.

Further downstream steps depend on the actual production line. A zinc-spraying quote does not itself include a complete tube mill, cutting saw or packing system.
03 / EXISTING XFX PRODUCT INFORMATION
What the XFX detail page actually lists.
The current saved detail page supports a small qualitative configuration summary. It does not provide a rated electrical or spraying-performance table.
Ask for the proposed machine's voltage, phase, frequency, input power, current, permitted line speed, applicable tube products, zinc-wire details and installation dimensions. These are quotation questions, not published ratings on the saved primary page.
04 / INFORMATION FOR SELECTION
Describe the tube and seam-treatment requirement.
A single maximum tube diameter cannot establish a suitable spraying arrangement. Share each actual product and the process it will run through.
Material and coating
Raw material and whether the strip or tube is galvanized or otherwise coated.
Tube shape and exact size
Round, square or rectangular dimensions for each product.
Matching wall thickness
Pair each exact size with its own thickness.
Line and weld details
Target line speed or output, existing or planned HF welding arrangement and seam position.
Spraying material
Existing zinc-wire or other spraying-material information, if already specified.
Site conditions
Electrical supply, workshop/installation space, layout and destination country.
Partial information is enough for first contact. Final suitability and electrical configuration are confirmed for the project, not assumed from the saved product photos.
05 / TWO BUYER ROUTES
Plan a new line or review an existing spraying system.
Discuss seam treatment early.
Send the material/coating, tube products with matching wall thicknesses, expected output, welding setup, required seam treatment, available zinc-wire information, electrical supply and layout.
Ask the proposal to separate the zinc-spraying scope from the main ERW tube mill and HF welder scope.
Discuss a new project ↗Start from the installed equipment.
Send the mill and sprayer make/model if known, tube list, speed, electrical supply, current wire/material and controls, available space, photos of the machine and seam-treatment area, surrounding equipment and the problem to solve.
Electrical requirements, installation dimensions, process position, control interfaces and production requirements must be reviewed before a replacement solution is confirmed. No direct compatibility is promised.
Send existing-machine photos ↗06 / QUOTATION REVIEW
Confirm exactly what the proposed equipment includes.
These are buyer review points, not standard inclusions. The project proposal controls the final supply scope.
Spraying configurationMachine type, spray gun, feeding arrangement and applicable products.
Electrical requirementsVoltage, phase/frequency, input and current values for the quoted configuration.
Controls and interfacesSeam position, line integration, controls and installation dimensions.
Consumables and guardingWire/material and accessories; guarding or enclosure where applicable.
Documents and sparesOperation/maintenance information and proposed spare-parts scope.
ServiceInstallation, commissioning, training and buyer-side preparations.
No coating thickness, adhesion, zinc consumption, corrosion test result or coating-life guarantee is stated here.
08 / FACTORY & SUPPORT
Discuss the spraying scope with XFX.
XFX has its own factory in China. For a project, XFX can provide on-site installation and commissioning, operator training, remote technical support, operation and maintenance documentation, and spare-parts support.
Overseas on-site arrangements and costs are confirmed in the individual proposal. No fixed installation duration, consumable price, maintenance interval or service-life claim is made here.

09 / BUYER QUESTIONS
Zinc Spraying Machine questions
What is this machine used for?
The XFX detail page describes applying zinc material to the weld-seam area of galvanized tube after ERW welding where that treatment is required.
Is this full-pipe galvanizing?
No such capability is stated by the saved XFX detail. The described application is local weld-seam treatment, not hot-dip or complete-tube galvanizing.
Does every GI tube mill need the same setup?
No. Review the material, process, required seam treatment, tube specifications, line speed and layout before deciding whether and how to include zinc spraying.
What should I send for a quotation?
Send material/coating, each tube size with matching wall thickness, planned speed, welding and seam-treatment details, available electrical supply and layout. Existing-machine photos help for upgrades.
Can XFX discuss replacing an existing sprayer?
Yes. Share the installed machine and control details, space, electrical supply and photos. The interfaces and production conditions must be checked before a solution is confirmed.
Is it included with every tube mill or HF welder?
No automatic inclusion is assumed. Ask the proposal to identify the zinc-spraying equipment and its scope separately.
What support can XFX provide?
Project arrangements may include on-site installation and commissioning, training, remote support, operation/maintenance documents and spare parts. Confirm scope and overseas costs in the proposal.
10 / DISCUSS ZINC SPRAYING
Send your tube list or photos of the current spraying area.
Tell XFX whether this is a new GI tube project, a separate machine purchase or an existing-line upgrade. Share sizes with matching wall thicknesses, material, welding setup, seam-treatment goal and available electrical information. Partial details are welcome.
