The product is intended to reduce internal corrosion of compatible metallic surfaces in oil and gas production and pipeline transportation systems.
Film-forming corrosion inhibitors work by adsorbing onto metal surfaces and forming a protective barrier that reduces contact between corrosive fluids and the underlying metal.
RXSOL Corrosion Inhibitor CI 3023, code RXSOL-81-8165-211.

Suitability for CO₂-containing or H₂S-containing fluids must be confirmed through representative corrosion testing. Inhibitor performance depends on fluid composition, temperature, flow conditions and metallurgy.
The intended corrosion inhibition mechanism involves:
Surface Adsorption: Active inhibitor components adsorb onto compatible metal surfaces.
Protective Film Formation: A barrier film reduces exposure of the metal to corrosive components.
Corrosion Rate Reduction: The protective layer helps reduce electrochemical corrosion reactions.
Film Maintenance: Continuous injection may be required to replenish the inhibitor film under flowing conditions.

Subject to system design and validation |
Example: For a pipeline carrying 100 m³/hour of fluid, a treatment rate of 10 ppm by mass corresponds to approximately 1 kg/hour of inhibitor if the treated fluid density is assumed to be 1,000 kg/m³.
For other fluid densities, the required inhibitor mass flow changes accordingly.
The actual injection volume also depends on the inhibitor's density.
Analyse the production fluid, including water cut, salinity, dissolved gases and other corrosive constituents.
Confirm pipeline metallurgy and operating temperature.
Select a suitable chemical injection point.
Establish the preliminary dosage through laboratory testing.
Inject continuously using a calibrated chemical dosing pump.
Monitor corrosion performance using coupons, electrical resistance probes or other approved techniques.
Adjust the injection rate according to measured corrosion performance.
Q1. What is the RXSOL equivalent of Corrosion Inhibitor KI 3939?
RXSOL identifies Corrosion Inhibitor CI 3023 (RXSOL-81-8165-211) as an alternative product. This is a catalogue cross-reference, not proof of identical formulation.
Q2. What is the main application of KI 3939?
The RXSOL-listed alternative is intended for film-forming corrosion protection in oil and gas pipeline systems.
Q3. What is the recommended dosage?
The published range is 6–12 ppm, but actual dosage must be validated under field operating conditions.
Q4. Can it protect against CO₂ and H₂S corrosion?
Potentially, depending on the formulation. Performance under sweet or sour service conditions must be verified through representative testing.
Q5. Is KI 3939 suitable for acidizing?
The available RXSOL cross-reference does not establish suitability for concentrated acidizing fluids. Acid corrosion inhibitors require separate testing for acid strength, temperature, exposure time and metallurgy.
Recommended tests include:
Corrosion coupon weight-loss testing.
Electrochemical corrosion testing.
Compatibility with crude oil and produced water.
Emulsion tendency assessment.
Thermal stability testing.
Film persistency testing.
Dynamic flow-loop testing where appropriate.
Compatibility with demulsifiers, scale inhibitors and other production chemicals.
Store in tightly closed, properly labelled containers in a cool, dry, well-ventilated location.
Use appropriate chemical-resistant gloves, eye protection and protective clothing.
Follow the finished-product SDS for handling, transport classification, fire precautions and spill response.
