Zinc-Aluminum Arc Spray Anti-Corrosion Coating for Tanks and Vessels

Application fields:

Storage tanks and pressure vessels, chemical and water tanks, offshore and port steelwork, steel bridges and lock gates, pipelines, and structural steel in humid, coastal or chemical environments.

Technical principles and processes:

The steel surface is prepared to a high standard by dry abrasive blasting to reach the required cleanliness and roughness, because bond quality depends on it. Zinc-aluminum (typically 85/15) wire is then arc sprayed in overlapping passes to a specified thickness. A sealer or topcoat is normally applied to extend service life.

Coating performance:

Sacrificial cathodic protection stops rust creep under the coating
Typical thickness 100-300 microns, applied in one or more passes
Bond strength suitable for immersion and atmospheric service
Service life of 15 years and beyond in moderate environments
Applicable on site or in the workshop for large fabrications

HVOF Tungsten Carbide Coating for Pump Shafts and Piston Rods

Pump shafts, piston rods and plungers carry seals and packings against a running surface, so wear there leads directly to leakage. A HVOF tungsten carbide coating gives that surface a dense, hard and corrosion-resistant layer that keeps the seal interface in good condition.

Arc Spray Coating for Large Wheels, Discs and Rotating Parts

Large wheels, discs, sheaves and rolls are expensive to replace and often impossible to source quickly. Arc spraying rebuilds their worn working surfaces and can add a wear or corrosion resistant layer at the same time, typically at a fraction of replacement cost.

Anti-Corrosion Surface Treatment for Steel Structures and Steelwork

For structural steel that has to survive decades of humid, coastal or chemical exposure, a thermally sprayed metal coating outperforms paint systems on its own. The sprayed layer protects the steel by sacrificial action, and the paint topcoat then only has to protect the coating itself.
