Cleaning & Contamination Control
Prepare industrial instruments and components for demanding service through application-specific cleaning, compatibility review, inspection, handling, and protected release.
In critical service, cleanliness is an engineered condition.
Oil, grease, moisture, lint, particulate, process residue, fabrication soil, and incompatible cleaning chemistry can affect measurement performance, damage equipment, or introduce serious hazards. The correct cleaning scope depends on the service media, materials, geometry, prior exposure, required cleanliness level, verification method, and final packaging.
Haygor’s cleaning and contamination-control services can include disassembly, compatibility review, mechanical preparation, selected cleaning chemistry, rinsing or flushing, drying, white-light or ultraviolet inspection, testing, labeling, and sealed packaging. Each job should be tied to a customer specification or an approved service procedure.
Choose the service path that matches the media, material, and end condition.
The current Haygor hierarchy includes seven specialized cleaning and inspection pages. Each route requires application-specific review.
Cleaning for Oxygen Service
Remove incompatible contamination and protect cleaned equipment for liquid or gaseous oxygen duty.

The exact chemistry and verification depend on the application, but a robust contamination-control scope generally addresses the same six decision points.
Identify the service
Define process media, equipment function, customer specification, cleanliness objective, and hazards.
Review compatibility
Confirm metals, polymers, seals, coatings, lubricants, electronics, and trapped-volume limitations.
Disassemble & prepare
Separate incompatible items and remove gross soil using approved mechanical or manual methods.
Clean, rinse & dry
Apply the selected chemistry, flushing, rinse quality, drying method, and environmental controls.
Inspect & verify
Use visual, UV, swab, fluid-comparison, residue, or other specified acceptance checks.
Protect & release
Reassemble if required, test, label, package, seal, document, and control post-cleaning handling.
Define the contamination, service media, and required end condition.
A generic “clean for service” request can hide critical differences in chemistry, acceptance, and packaging.
No single method proves every type of contamination has been removed. White light, UV-A, swabs, recovered fluid, gravimetric or chemical residue tests, and functional checks answer different questions and must be matched to the governing requirement.

- Previous process media, contamination, cleaning history, lubricants, coatings, and hazardous residue
- Intended service media, pressure, temperature, flow path, ignition risk, and compatibility requirements
- Customer procedure, industry specification, cleanliness limit, and inspection or residue-test method
- Disassembly, repair, calibration, leak test, reassembly, labeling, and certification requirements
- Rinse quality, drying gas, clean handling, bagging, sealing, shipment, and turnaround needs
Build the complete Haygor service route.
Connect this service with related cleaning, machining, repair, calibration, coating, or assembly work when the application requires a broader scope.
Send the component, contamination history, and required release condition.
Haygor can review compatibility, cleaning methods, verification, testing, documentation, and packaging before preparing the service scope.
