Coil Tubing Corrosion Inhibitor CTI
SKU::RXSOL-44-2065-200
Protects carbon steel tubing against CO2/H2S attack. It disperses easily in brines, forms a persistent barrier, and extends tubing life during acidizing and workover operations.
A highly effective, film-forming corrosion control agent specifically designed for oil and gas production and transmission systems operating under sour gas (H₂S) and acid gas (CO₂) conditions. This Coil Tubing Corrosion Inhibitor has exceptional film persistency and ability to adhere to metal surfaces even under high turbulence and wet gas conditions.
Protects carbon steel coil tubing against CO2/H2S attack. It disperses easily in brines, forms a persistent barrier, and extends tubing life during acidizing and workover operations.
Proprietory blends improve solvent penetration and spreading across pipeline surfaces, enhancing the delivery of the active corrosion-inhibiting molecules. It assists in reducing surface tension, allowing better wettability and contact with metal substrates, especially in two-phase flow lines (liquid + gas). It is carefully formulated to ensure complete compatibility with hydrocarbon fluids, high solubility, and fast film formation on carbon steel surfaces.
The active components in this product form a mono-molecular film that adsorbs onto metal surfaces, acting as a barrier to prevent corrosive agents (such as CO₂, H₂S, and water) from coming into contact with the metal. This product is designed for continuous or batch injection through injection quills, downhole tubing, or pipeline drips. It has been field-tested under various pressure and flow regimes and has demonstrated consistent corrosion rate reductions in both onshore and offshore applications.
Hydrogen sulfide (H2S) naturally occurs and may already by present information can be the result of sulphate reducing bacteria (SRB) in your process systems. Ones established, it can potentially be carried in hydrocarbon streams, resulting in servere gatharing lines, creating high failure rates in your production.
Through strategic H2S scavenger applications and speciality chemicals, RX Marine International chemicals experts can help reduce H2S levels and lower overall solids in your system, reducing any gas or fluid souring while controlling corrosion.
If you encounter hydrogen sulfide in your system, RX Marine International can perform a fluid compatibility test to determine H2S levels and customize a chemical solution to fit your production needs.

- Designed for use in a wide range of completion and workover brines (NaCl, KCl, CaCl₂, CaBr₂).
- Compatible with most scale inhibitors, oxygen scavengers, and non-ionic surfactants.
- Avoid high concentrations of strong anionic surfactants, which can displace the protective film.
- Works by chemisorption of amine/imidazoline groups onto the steel surface, producing a hydrophobic barrier.
- A pre-film treatment ensures maximum performance during subsequent corrosive fluid exposure.
- Provides effective protection in CO₂ and H₂S environments commonly encountered during well interventions.
- Performance should be validated by wheel test or coupon test under site-specific fluids and temperature.
- Should be used in combination with an acid corrosion inhibitor when coiled tubing is exposed to strong acids.
- Pre-filming with this inhibitor helps minimize attack during initial acid contact.
- Stable and effective up to ~120 °C under typical downhole pressures.
- For higher temperature acid jobs, intensifiers (e.g., iodides) may be required.
- Contains organic amines—handle with appropriate PPE (gloves, goggles, protective clothing).
- Store in closed containers between 5–40 °C, away from acids and oxidizing agents.
- Shelf life: 18–24 months under proper storage conditions.
- Nonylphenol-free formulation; uses biodegradable surfactants where possible.
- Always comply with local discharge and environmental regulations before field use.
