Corrosion Coating for
Petrochemical and Oil
Corrosion and erosion resistant coatings for pumps, valves, plungers and structural steel working in sour service, chloride-rich and offshore environments where downtime is measured in lakhs per hour.
Components We Coat in Petrochemical and Oil
Gate and ball valve seat hard-facing
Pump impeller and casing erosion protection
Plunger, piston rod and sleeve coatings
Offshore structural steel and pipe corrosion defence
Heat exchanger tube sheet protection
Typical Outcome
Typical outcome: sealed TSA and carbide systems clear 2,500-hour ASTM B117 salt spray with no substrate attack.
Coating Processes Used
HVOF for dense, sub-1% porosity carbide hard-facing
Twin wire arc spray for nickel alloy corrosion barriers
Wire flame spray (metallizing) of aluminium for offshore steel
Coating Materials Specified
WC-Co-Cr for erosion plus corrosion duty
Inconel 625 and Hastelloy wire for sour service
Thermally sprayed aluminium (TSA) to NORSOK M-501 practice
Chrome carbide NiCr for high-temperature erosion
