PRODUCT INTRODUCTION
Corrosion Inhibitor is a high-performance industrial chemical designed to protect metal surfaces from corrosion in water systems, pipelines, heat exchangers, storage tanks and production equipment. It works by forming a thin, stable protective film on metal surfaces, blocking electrochemical corrosion reactions and reducing contact between corrosive media and the base metal.
This product is widely used in power plant circulating water, oil and gas production, refinery processing, chemical industry, marine engineering, central air conditioning and metal processing industries. It is particularly effective against carbon steel corrosion, pitting corrosion, crevice corrosion and microbial corrosion under complex water quality and operating conditions.
The Corrosion Inhibitor series includes liquid and solid formulations, suitable for different system materials, temperatures, pH ranges and chloride levels. It can be used together with scale inhibitors, biocides and dispersants after compatibility confirmation. Proper dosage control reduces corrosion rate, extends equipment service life, improves operational reliability and lowers maintenance costs.
Every batch is tested for corrosion inhibition efficiency, pH value, density, viscosity, solid content and compatibility before shipment. We provide complete export documents including COA, TDS and SDS(MSDS) for quality traceability and customs compliance. Our technical team can recommend the most suitable grade and formula according to your system material, operating temperature, water quality and destination country regulations.

USAGE NOTES
Dosage Control:
The recommended dosage is 3–20 ppm depending on system material, temperature, water quality and corrosion level. Start from lower dosage and adjust according to corrosion test results and field monitoring data.

Dosing Method:
Use continuous dosing with metering pump. Dilute with clean water if required and ensure uniform mixing at the dosing point. Avoid direct mixing with strong acid or strong alkali chemicals without compatibility confirmation.

Compatibility Check:
Before mass use, test compatibility with scale inhibitors, biocides, dispersants and other additives. Observe precipitation, foam change and corrosion rate. For EU export, REACH SVHC screening is suggested.

Process Condition Consideration:
Adjust dosage according to temperature, chloride, pH, flow rate and system material. High temperature, high chloride and low pH conditions may require special grade or higher dosage.

COMMON PROBLEMS IN DOWNSTREAM PRODUCTION
Corrosion Rate Still High After Dosing
Insufficient dosage, wrong grade, high chloride, low pH or unsuitable material compatibility may reduce protection.
Solution: Re-analyze system condition, select matching grade, adjust dosage and optimize pH control.
Localized Pitting Corrosion
Poor film formation, differential aeration, microbial activity or uneven inhibitor distribution causes pitting.
Solution: Improve dosing uniformity, add biocide if needed, select pitting-resistant grade and monitor key points.
Scale Forms While Using Corrosion Inhibitor
Some corrosion inhibitors may promote scale if formula is not balanced for hardness and alkalinity.
Solution: Use CI-500 dual function grade, test water quality and combine with scale inhibitor if required.
Compatibility Problem with Other Additives
Mixing corrosion inhibitor with scale inhibitor, biocide or flocculant without test may cause precipitation.
Solution: Conduct jar test before full use, separate dosing points and adjust chemical order.
Film Formation Slow at Low Temperature
Low temperature reduces inhibitor adsorption and film forming speed.
Solution: Increase dosage slightly, extend contact time and use low-temperature resistant grade.
Corrosion Inhibitor Causes Foam or Emulsion
Wrong formula, high turbulence or incompatible additives cause foam and emulsion problems.
Solution: Select low-foam grade, test compatibility and add defoamer if necessary.
Customs Detention Due to Mismatched Documents
Incorrect HS code, CAS number or SDS information triggers inspection and detention at destination ports.
Solution: Confirm destination country regulations before order. Standard export data: HS Code 3824.9999, CAS No. 7601-54-9 (reference), EINECS 231-566-5 (reference), non-hazardous. We supply consistent full-set SDS / COA documents.
Batch-to-Batch Performance Variation
Changes in water quality, operating conditions, temperature or dosing method cause inconsistent results.
Solution: Standardize Corrosion Inhibitor grade and dosage, monitor corrosion rate and test each incoming batch.
