deoxygenation sterilization and corrosion inhibitor

Applications and Performance

　　This product is a highly efficient liquid compound agent composed of polyol phosphate esters,polymers,quaternary ammonium salts,and additives.It is a three-in-one mixture of deoxygenator,bactericide,and corrosion inhibitor.It is miscible with both seawater and freshwater.It is particularly suitable for corrosion inhibition,scale inhibition,bactericidal and algae-killing protection of carbon steel metal in seawater cleaning,pressure testing,and seawater storage systems for subsea pipelines.

Main Features

　　Excellent deoxygenator,bactericide,and corrosion/scale inhibitor effects;
　　Miscible with both seawater and freshwater;
　　Non-toxic,harmless,and bio-friendly;
　　Compatible with API 5L PSL2 X65 and Inconel 625 steel subsea pipelines,compatible with Duplex 2205 hoses,and compatible with 316L mechanical composite lined pipes.

Instructions for Use

　　Continuously inject via metering pump,adding the required dosage to the subsea pipeline or other system to be protected(dosage in seawater:500 mg/L).Avoid prolonged exposure to air during use to prevent reduction of the deoxygenator's effectiveness.Stir thoroughly before use.

Packaging,Transportation,and Storage

　　1 cubic meter/tank,25 liters/drum,200 liters/drum,or as required by the tendering party.Storage tanks are equipped with
　　well-sealed relief valves and plugs to meet lifting and handling requirements.
　　Do not store with oxidizing or reducing agents.
　　Store at room temperature(0-30℃)and normal pressure,away from light.Shelf life is 12 months.

　　In the field of industrial water treatment,corrosion,microbial growth,and excessive dissolved oxygen are the three core challenges.The combination of these issues not only shortens equipment lifespan and reduces system efficiency,but may also lead to safety hazards.Deoxygenation sterilization and deoxygenation sterilization and corrosion inhibitors,as a type of composite water treatment agent,provide comprehensive protection for industrial circulating water,boiler water and other systems through the synergistic effect of"one agent,multiple effects".This article will systematically analyze the core value of this key product from four dimensions:technical principles,component composition,application scenarios,and selection points.

　　1、Technical principles

　　The core advantage of deoxygenation sterilization and corrosion inhibitors lies in their composite functional design,which achieves three major goals through physical and chemical interactions:

　　Deep deoxygenation to block the source of corrosion:Dissolved oxygen is one of the main causes of metal corrosion.This type of medication converts dissolved oxygen in water into harmless substances through chemical reduction reactions.For example,isoascorbic acid and its sodium salt can act as deoxidizers,quickly reacting with oxygen to generate water and carbon dioxide,reducing the oxygen content in boiler feedwater to below 7μg/L,far below the national standard(≤15μg/L).This reaction is not only efficient,but also does not introduce secondary pollutants.

　　Broad spectrum sterilization and inhibition of microbial contamination:Microorganisms in industrial water systems can form biofouling,causing corrosion under scale and increased thermal resistance.Non oxidizing fungi
