External pipework and tank corrosion protection
External corrosion attacks pipework, valves, fittings, and tank walls at supports, weld seams, and coating gaps until metal loss hits inspection limits.
What is failing
External corrosion concentrates at pipe supports, girth welds, valve bodies, fittings, and tank walls where moisture sits and coatings break down. Left alone, metal loss creeps toward inspection limits and forces the line out of service for replacement. Cutting out and re-welding corroded pipe means hot-work permits, a shutdown, and lost production.
How AAS does it
AAS prepares the steel by blast or hand tool to a sound profile, then applies a cold-cure protective coating over pipe runs, girth welds, valves, and tank shells. Contoured fittings and weld crowns get full coverage by hand where a sprayer cannot reach. A surface-tolerant system such as Belzona 1391T or a 5811 barrier coat bonds to in-service steel without taking the line down.
Typically applied with Belzona 1391T, Belzona 5811, matched to the service conditions.
The facility keeps the line running and stops the metal loss before it reaches a code trigger. External surfaces gain a fresh corrosion barrier and the asset earns years of added service.
How AAS delivers it
AAS performs External pipework and tank corrosion protection work for Oil & Gas, Petrochemical & Chemical, and Water & Wastewater operations across Baton Rouge and Louisiana, cold-applied and in place wherever possible, on your turnaround schedule. Crews are factory-trained Belzona applicators, the repair system is matched to the service conditions it will see, and urgent failures are covered by 24-hour on-call response. The result is a permanent, engineered repair that returns the asset to service without the cost or downtime of full replacement.
