Zinc Spray Gun for Tube Mill | Galvanizing Repair & Weld Seam Protection
In modern tube mill production, corrosion protection is not something you can ignore—especially at the weld seam. This is where a zinc spray gun becomes extremely practical.
Instead of relying only on traditional galvanizing, many factories today use zinc spraying as a fast and flexible way to repair damaged coating areas. It’s widely applied in weld seam protection, galvanized surface repair, and anti-rust treatment for steel pipes.
Compared with hot dip galvanizing, zinc spraying doesn’t require a full production process or immersion in molten zinc. It’s quicker, easier to control, and much more suitable for localized treatment or post-weld repair.
What is a Zinc Spray Gun?
A zinc spray gun is a thermal spraying device that melts zinc wire or powder and projects it onto a steel surface, forming a protective coating.
In simple terms, it allows you to “rebuild” the zinc layer exactly where it is needed.
You’ll typically find it used in:
- (1) ERW tube mills
- (2) Steel pipe production lines
- (3) Weld seam protection
- (4) Galvanized pipe repair
Once applied, the zinc coating acts as both a barrier and a sacrificial layer, meaning it protects steel even if the surface is slightly damaged.

Why Zinc Spray Gun is Important in Tube Mill
During high-frequency welding, the original galvanized layer at the seam is usually burned off. If nothing is done:
- 1. Rust can appear very quickly
- 2. Pipe durability drops
- 3. Export quality may fail inspection
Zinc spraying solves this problem directly. It restores the protective layer right after welding, helping the pipe maintain corrosion resistance without slowing down production.
From a practical standpoint, it’s not just protection—it’s quality control insurance.
