At high temperature of 250 Deg C HEDP also resulting good corrosion and antiscaling effect. 

It's good resistance towards High and Low pH value makes it unique and better than that of other organophosphoric acids (salt). HEDP also resulting high chlorine oxidation tolerance properties.

HEDP can react with metal ions in water system to form hexa-element chelating complex, with calcium ion in particular. Therefore, HEDP has good antiscale and visible threshold effects. When built together with other water treatment chemicals, it shows good synergistic effects. 
HEDP is used as scale and corrosion inhibition in circulating cool water system, oil field and low-pressure boilers in fields such as electric power, chemical industry, metallurgy, fertilizer, etc.. In light woven industry, HEDP is used as detergent for metal and nonmetal. In dyeing industry, HEDP is
used as peroxide stabilizer and dye-fixing agent; In non-cyanide electroplating.
