Oil & Gas Valve and Bundle Cleaning, Ultrasonic
Hydrocarbon processing leaves the hardest deposits in industry: coke, asphaltenes, polymerised residues and mineral scale bonded onto valves, exchanger bundles and downhole tooling. Inspection and recertification require them gone — without dimensional damage to sealing faces.
Misonics systems take wellhead, process and turnaround components to inspection-ready condition in documented, repeatable cycles, with chemistry matched to hydrocarbon soils and oil separation engineered into the machine.
What we remove in oil & gas
Coke & asphaltene build-up
Thermally bonded onto process internals, resistant to solvents and mechanical cleaning.
Mineral scale
Carbonate and sulphate scale on water-side and exchanger surfaces.
Heavy hydrocarbon films
Crude residues, waxes and greases through valves, actuators and fittings.
Catalyst fines & particulates
Abrasive fines lodged in coalescer housings, strainers and instrument hardware.
Corrosion products
On carbon-steel components ahead of NDT, where surface condition decides the inspection.
Engine and inlet components, before and after
Diesel inlet components from field service, photographed as received and after a documented cycle.
Inlet port bore. Hard carbon in the port bore of a working engine, out without cutting or blasting.
Runner twin ports. Both runners packed solid on the left, both open on the right.
Real parts, real materials
Valves & wellhead
Ball valves, gate valves, actuators, Christmas-tree components — cleaned seat-safe ahead of test and recertification.
Heat transfer
Exchanger bundles and plate packs — coke and scale out of tube bundles in purpose-sized tanks.
Downhole & rotating
Downhole tooling, pump internals and rotating-equipment components on turnaround schedules.
Cavitation cleans geometry it cannot see
Bubble collapse at the liquid–metal boundary lifts contamination from passages, galleries and cavities without anything touching the surface. Nothing abrades, nothing embeds, no metal is removed.
The VarioSonic G4 tracks the transducer array as temperature and load shift — conversion efficiency up to 95%.
Eliminates standing-wave hot and cold zones across a loaded basket.
Stored recipes and logged cycles — audit evidence produced as a by-product of running.
Multi-stage filtration and weir oil capture hold results steady as the bath loads.
Most faults identified — many resolved — without a site visit.
Heavy 316 stainless tanks, tested before despatch, every wearing part replaceable.
The machine follows the process
From manually loaded single-tank units to automated lines — and engineered systems where the catalogue ends.
Matched to the soil and the substrate
Coke and asphaltene respond to hot heavy-duty alkaline chemistry with long staged cycles; oil separation and filtration are engineered in, because bath life is an operating cost.
