Oil & Gas Coating & Repair Services

Exchangers lose efficiency two ways. Dissimilar tube metals set up galvanic corrosion at the tube sheet and water box, and that eats the steel around every tube end while the bare metal invites more attack. We rebuild and electrically isolate the joint with ceramic-filled epoxies, prep the water box, and recoat it inside the turnaround window. No hot work near the bundle, and the unit is back in service in days rather than weeks. Pumps go a different route: erosion-corrosion and cavitation reshape the impeller vanes and casing profile until the pump falls off its head curve. Our crew rebuilds the vane geometry and casing wear areas cold, then lays down a smooth coating that restores the hydraulic profile, and efficiency comes back with no rebalancing for weld heat.

Valves, shafts, and machinery housings take the same in-place treatment. We rebuild eroded valve bodies and bonnet faces, machine worn journals and keyways back to the specified diameter, and repair compressor and gearbox casings at the bearing bores and split lines. Flange faces get the gasket-witness surface reformed against the mating flange with a release agent, so the repaired face mirrors its partner exactly and the spool never leaves the line.

Bends, tees, and elbows wear first, because every change of direction concentrates erosion and corrosion right where the flow turns. We line and wrap the contoured fitting with a composite that follows its geometry, so nobody cuts the spool out and re-welds it. Through-wall corrosion, external pitting, and mechanical damage on pressurized lines take an engineered resin-and-fiber composite wrap applied with the line still online. The work is qualified to the recognized composite-repair standards ISO 24817 and ASME PCC-2. The pipe gets its design pressure rating back without a replacement turnaround.

When a line is already weeping, we seal it live. Our crew stops the active leak cold with the line still pressurized, then overwraps for a permanent fix. Production keeps running, with no hot-work permit and no product evacuation. A flange joint that corrodes and weeps at the gasket face gets encapsulated in a cold-cure compound that seals the joint and protects the bolting, leaving the assembly free for future disassembly. Live-leak and emergency work is exactly what the on-call line exists for.

Tank floors corrode from the underside first. Rainwater wicks in at the steel-to-foundation chime and works on the floor plate through every wet cycle. We seal that chime with a flexible cold-applied coating and reinforce the inside rim during the routine inspection window. Inside the tank, stored product thins the floor and the floor-to-shell weld wherever stagnant material settles, so we lay a cold-cure lining as one continuous film over the prepared interior. No welds to recoat, no heat soak. Separators, knock-out drums, and process vessels that corrode at the water leg, welds, and access ports take the same in-place lining, matched to their service.

Containment is the other half of the job. Bund walls spall from the inside out and open cold-joint cracks until they stop holding their rated volume. We rebuild the spalled face, cap it with a barrier coating, and add a chemical-resistant overlay where the spill chemistry demands it. The facility holds the volume its SPCC plan requires without demolition and recast.

Corrosion under insulation is the failure this sector fights hardest. Wet insulation holds moisture against a hot wall, and inspectors only find the metal loss once it is already severe. We brush a barrier coating onto the hot surface under the insulation while the line stays in service, and it protects the steel across the CUI temperature band. Where cladding leaks at seams, support legs, and penetrations, we seal the jacketing with a reinforced membrane and weather-side coating so the water never reaches the pipe again. Vessels and pipework that cannot be cooled or drained get coated in place with high-temperature linings that cure on the operating surface, and the asset keeps running.

Every repair here is built around one outcome. The equipment goes back in service inside the outage you already scheduled. Cold-cure work means no permit-driven hot work, no re-stamping of code vessels, and no waiting on OEM lead times. Our crew preps, repairs, and coats in the field, and whatever comes off the unit is finished in our climate-controlled Alvin shop. For Texas Gulf Coast refiners, petrochemical producers, and marine operators, that is downtime avoided and a turnaround that lands on its dates.
