Applications of Online Zinc Spray Coating System for Tube Mill

• Corrosion Protection: Structural steel, bridges, pipelines, marine structures, and offshore platforms. Long-term rust prevention in harsh environments.
• Power Transmission & Utility Poles: Zinc spray coating extends the life of electric poles and towers by resisting oxidation.
• Automotive & Transport: Underbody parts, chassis components, and truck bodies for extended anti-rust protection.
• Shipbuilding & Marine Industry: Coating of hulls, decks, and metal fixtures exposed to seawater.
• Wind Energy Sector: Tower sections, offshore wind turbine components, and foundation structures.
• Industrial Fabrication: Steel frameworks, tanks, and silos requiring enhanced surface durability.
• Oil & Gas Industry: Offshore rigs, subsea structures, and refinery components.
• Galvanizing Line Replacement: Alternative to hot-dip galvanizing for large or pre-assembled structures.

An online zinc spray coating system, also known as an inline arc spray zinc coating machine, is a thermal spray galvanizing process designed to apply zinc or zinc-aluminum alloy onto steel tubes as they pass through a tube mill production line.

Instead of immersing the tubes in a molten zinc bath, the system melts zinc wire using an arc spray gun or flame spray gun, atomizes it with compressed air, and sprays it onto the tube surface. This results in a strong, adherent, and corrosion-resistant zinc coating.

Online Zinc Spray Coating System

In the steel tube manufacturing industry, corrosion protection is one of the most critical requirements. Steel tubes used in construction, automotive, oil & gas, and water supply lines are constantly exposed to moisture, chemicals, and harsh weather conditions. Without effective protection, corrosion can significantly reduce their lifespan and performance. Traditionally, hot-dip galvanizing has been the go-to method for applying a protective zinc coating. However, it comes with limitations such as high energy costs, production delays, and restrictions on coating certain shapes and pre-assembled structures. This is where the online zinc spray coating system for tube mills offers a faster, more efficient, and cost-effective solution.

By integrating directly into the production line, this inline zinc spray coating system applies a uniform zinc coating on steel tubes immediately after fabrication, ensuring long-lasting corrosion resistance without interrupting production.

Additionally, it is crafted from premium-grade metal by our experienced professionals to established industry standards. Our offered zinc spray booth for Tube Mill is made available in various terms for our clients at reasonable prices.

How Zinc Spray Coating System Works

Zinc wire pulling framework by DC Motor, fitted in the firearm, which guarantees accurate wire feed speed. The wires meet at the top of the weapon and dissolve in the electrical bend. The liquid mass is atomized and blown onto the substrate with a compacted zinc spray gun. The particles cool to encompassing temperature and mix into a great metal covering. 

The online zinc spray coating system for tube mill separation from the circular segment to the cylinder crease is a significant estimation of tube plant establishments. Standard bend splash air covers give funnel-shaped shower designs. Straight augmentations give curved examples. A little shower width limits the over-splash air breather and absolutely controls the material to use. 

Introducing the circular segment splash firearm in an encased box ventilated to a residue gatherer guarantees natural and staff security. Residue, exhaust, and overspray should be eliminated from the splash zone rapidly. Over-shower can contain particles of under 2 microns in the estimate and can establish 4 to15% of the over-splash by weight. If not appropriately ventilated, this could cause a perilous breathing zone or obstruct factory tasks downstream; consequently effective residue assortment framework is essential.

Components of an Online Zinc Spray Coating System

• Arc Spray Gun / Flame Spray Gun: Melts and atomizes zinc wire for coating.
• Zinc Wire Feeder: Ensures consistent feeding of the zinc wire into the gun.
• Power Supply Unit: Provides stable voltage and current for arc melting.
• Compressed Air Supply: Atomizes molten zinc into fine particles.
• Dust & Fume Extraction System: Ensures a safe and clean working environment.
• Automatic Carriage or Manipulator: Moves the flame spray gun evenly around the tube circumference.
• Control Panel (PLC): Enables automation, speed control, and process monitoring.
• Cooling System: Ensures proper curing of the zinc coating.

Advantages of Online Zinc Spray Coating in Tube Mills

• Continuous Operation: The system works in line with tube mill production, eliminating the need for separate galvanizing processes.
• Energy Efficiency: Uses significantly less energy than heating a molten zinc bath.
• Customizable Coating Thickness: Easily adjustable between 50 to 200 microns, depending on application requirements.
• Environmental Benefits: No hazardous molten zinc fumes or large-scale acid cleaning as in hot-dip galvanizing.
• Strong Adhesion: Meets or exceeds adhesion requirements of ASTM D4541 and similar standards.
• Lower Production Cost: Reduces handling, transportation, and processing time.
• Versatile Applications: Works for round tubes, square tubes, and rectangular hollow sections.

Coating Properties
An online zinc spray coating system for tube mill, any metal sprayed deposit exhibits some degree of porosity (hence the need to apply slightly thicker sprayed deposits than the pre-coatings, which are hot-dip. The 'as-sprayed' deposit has a fine satin appearance, surface finish. After spraying, the sand blasting machine, the sizing roll stations of the tube mill will slightly deform the sprayed deposit to produce a flattened, partially shiny appearance. The sizing operation will also reduce surface porosity. The sprayed coating will withstand deformation and manipulation.
