Anti-Corrosion Surface Treatment for Steel Structures and Steelwork

Application fields:

Industrial plant structures, pipe racks and platforms, steel frames in chemical plants, coastal and offshore structures, water treatment works steelwork, and refurbishment of rusted fabricated steel.

Technical principles and processes:

Existing rust and old coating are removed by abrasive blasting to the specified surface preparation grade. A zinc or zinc-aluminum coating is applied by arc spray, followed by a sealer and a compatible topcoat system. Adhesion and thickness are inspected before the topcoat is applied.

Coating performance:

Combined system life substantially longer than paint alone
Sacrificial protection tolerates local mechanical damage
Coating thickness 100-200 microns before topcoat
Suitable for coastal, humid and mildly chemical atmospheres
Inspection record covering preparation, thickness and adhesion

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.

On-Site Pipeline Thermal Spray Coating and Field Repair

Many pipelines and large steel components cannot be moved to a coating workshop. Our mobile crews prepare the surface and apply the coating on location, restoring corrosion protection or wear resistance with minimal disruption to production.
