Performance:
This product, developed through extensive laboratory testing and field application improvements, is a high-efficiency scale and corrosion inhibitor. When used in recirculating cooling water systems, it provides excellent corrosion inhibition for metals such as carbon steel, stainless steel, and copper. It strongly inhibits scale deposition and has outstanding dispersing properties for foulants.
Application:
As a scale and corrosion inhibitor, it can be widely used in open recirculating cooling water systems in petroleum refineries, deep petroleum processing plants, and deep natural gas processing plants.
Usage Method:
Dosage varies depending on the water quality indicators and process parameters of the application system. Generally, based on the makeup water volume, the dosage concentration should be controlled at around 20-50 mg/L. Suitable for pH range 7.0 – 9.5.
Packaging, Storage & Transportation:
Packed in 25 kg, 200 kg, or 1000 kg plastic drums. Store in a cool, dry place. Shelf life is twelve months. Handle with care during transportation to prevent impact.
