Valve body restoration
Body erosion at the flow path, seat-and-stem wear and gasket-face corrosion retire valves before the trim or actuator fails.
What is failing
Erosion at the flow path, seat-and-stem wear, and corrosion at the gasket face retire a valve while its trim and actuator are still good. A worn body will not hold a seal and becomes a leak and emissions risk. Cutting a welded valve out of the line for replacement is a hot-work job and a long line break.
How AAS does it
AAS rebuilds eroded body cavities and bonnet faces cold with machinable composites such as Belzona 1111, then overcoats the flow path with an erosion-resistant layer like Belzona 1321. The crew prepares the wasted internals, rebuilds them to profile, and reforms the gasket faces in place. The valve is restored without cutting it out for welding.
Typically applied with Belzona 1111, Belzona 1321, matched to the service conditions.
The valve body holds a seal again and goes back into the line. The facility keeps the existing valve and its trim instead of buying and welding in a replacement.
How AAS delivers it
AAS performs Valve body restoration 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.
