In oxygen service, oil is fuel
In high-purity oxygen and hydrogen systems, even a trace of hydrocarbon can ignite under pressure. Valves and components for these services must be certified oil-free. Our five-step process removes every trace of oil, grease and hydrocarbon, then seals the part clean until it reaches the plant.
* Meets the ASTM G93 oil-free standard for oxygen and hydrogen service.
The 5-step cleaning process
A certified process ensuring complete contaminant removal for the stringent oil-free requirements of global industrial gas standards.
Pre-cleaning (dry-ice blasting)
High-velocity CO2 strips heavy scale, baked-on gasket material and oil deposits from the surface.
Ultrasonic wash
Disassembled parts are immersed in a bath to lift residual oil from threads, ports and springs.
Rinse & dry
A deionized-water rinse followed by oil-free filtered air drying prevents flash rust and recontamination.
UV inspection
A darkroom UV inspection confirms 100% removal of hydrocarbon traces.
Vacuum packing
The oil-free part is vacuum-packed to guard against moisture and oxidation.
Certified oil-free capability
ASTM G93 standard
The full process is designed to the ASTM G93 oil-free requirement for oxygen and hydrogen service.
UV-verified clean
A darkroom UV inspection confirms 100% removal of hydrocarbon traces before the part is sealed.
Vacuum packed
Cleaned parts are vacuum-packed, staying oil-free from workshop to plant.
