ARDROX 1873A – Turbine Engine Component Descaler

Ardrox® 1873A is used diluted with water at a concentration of 20 % to 25 % by volume in water. The operating temperature is 80 °C – 85 °C (176 °F – 185 °F). Parts should be free from oil and carbonaceous deposits.

Product Description

Ardrox®1873A is a concentrated liquid mixture of sequestrants and surfactants. It is mildly acidic. Ardrox®1873A has been formulated specifically to descale the chrome steels, stainless steels, nickel and cobalt alloys used in the manufacture of aircraft turbine engines. During service these parts become covered with hard adherent oxide scale, which must be removed during overhaul periods to enable penetrant inspection processes to be carried out.

FEATURES

When Ardrox® 1873A is used in the prescribed manner no significant corrosion will occur on ferritic stainless steels and nickel and cobalt heat resisting alloys. It also has no effect on pack aluminizing and little effect on chromium carbide plasma coatings. Ardrox® 1873A is not suitable for use on carbon or low alloy steels.

APPLICATIONS:

Ardrox® 1873A is used diluted with water at a concentration of 20 % to 25 % by volume in water. The operating temperature is 80 °C – 85 °C (176 °F – 185 °F). Parts should be free from oil and carbonaceous deposits.
Immersion times should be approximately 15 minutes
Since Ardrox® 1873A solutions are acidic, the process stage must be followed by a thorough water rinse.
When dealing with heavy scale, it is better to use several cycles of approximately 15 minutes rather than giving extended immersion times.
