Introduction:

Metals are widely used in the construction of equipment associated with aqueous systems in which metals remain in contact with aqueous fluids on a regular basis, for example, hydro-testing of metallic equipments, fire extinguishing systems containing water, cooling or heating systems, heat exchangers and many more. The aqueous system generally contains vessels, piping, valves etc. When water comes in contact with these systems, corrosion of the metal, during and after contact, is a concern. SAC-CI 100 when added to water in small concentrations are able to prevent corrosion during wet storage. The corrosion inhibitor prevents corrosion even after vacating water from the system.The mechanism of SAC-CI 100 corrosion inhibitor is to prevent corrosion of metals in three phases: within the solution, at the water line, and above the water line. It also prevents corrosion in the areas which are not reachable with other corrosion inhibitors.

Features and benefits of using SAC-CI 100:

 No heavy metals

 Provides up to 24 months of continuous protection

 Provides mono-molecular inhibiting layer (protection layer)

 

Additional benefits:

 The product provides vapour-phase inhibiting action which protects inaccessible and recessed surfaces

 No regeneration required; effective for up to 24 months

 If the protective layer is disturbed by moisture or opening of the enclosed space, the layer is replenished by continuous vapour protection

 Little or no surface preparation required and easy to apply

 Prevents further corrosion of the pre-coated and painted surfaces

 The protection layer does not need to be removed prior to processing or use

 The protection layer does not interfere with operation of mechanical components

 

Application and additional applications:

Typical aqueous systems include, but are not limited to, open re-circulating cooling systems, closed loop cooling systems, boilers and similar steam generating systems, fire fighting systems where water remains in constant contact with water, heat exchange equipment, reverse osmosis equipment, oil production systems, flash evaporators, desalinization plants, gas scrubbers, blast furnaces, paper and pulp processing equipment, steam power plants, geothermal systems, food and beverage processing equipment, sugar evaporators, mining circuits, bottle washing equipment, soil irrigation systems, closed circuit heating systems for residential and commercial use, aqueous-based refrigeration systems, down-well systems, aqueous machining fluids (e.g. for use in boring, milling, reaming, broaching, drawing, turning, cutting, sewing, grinding and in thread-cutting operations, or in non-cutting shaping, spinning, drawing, or rolling operations), aqueous scouring systems, aqueous glycol anti-freeze systems, water/glycol hydraulic fluids, ferrous-surface pre-

treatment, polymer coating systems, and the like. Various types of water may be utilized in such systems, for example fresh water, brackish water, sea water, brines, sewage effluents, industrial waste waters, and the like.

Additionally the product is very suitable for the following:

 

Hydro-testing

 Long term storage of water

 Tubular structures, pipes and vessels

 Internal surfaces of compressors, turbines, engines, tanks, boilers, heat exchangers

 Closed circuit cooling systems

 Equipment protection after hydrostatic testing

 

Metals protected:

Carbon steels, Mild steels, Stainless steels, Copper, Brass, Aluminium

 

Direction for use:

The product dose depends on quality of water and corrosive tendency of atmosphere also in some cases. But in general 10 to CI 1000 ppm is sufficient. More particularly, the dose may be 300-500 ppm. The product may be dosed by a slug feed or by blending with the aqueous fluid as the system is being filled. One can dose the material continuously using metering pump also.

The pH of the aqueous system in which the product may be applied ranges from about 5 to about 12. The pH is preferably in the range from about 6 to about 10.

The dosage can be increased for more severe conditions.

 

Storage:

Store in a sealed container in a dry warehouse, avoiding direct exposure to sunlight, with temperatures not exceeding 150°F (66°C). Under these conditions, shelf life is up to 24 months.

 

Packing:

The product is available in 50 to 200kg HDPE carboys.
