Boiler Corrosion Inhibitors | ChemTreat, Inc.

Apr 23, 2018 · HEDP accounts for a large proportion of all organophosphate corrosion inhibitor products. HEDP is also one of IROCHEM's main products. It is well known that HEDP is an organic phosphonic acid scale inhibitor. It can form a stable complex with metal ions such as iron, copper, and zinc. HEDP can remove and reduce metal ions in water very well. HEDP can dissolve the oxide on the metal surface.

Corrosion & Scale Inhibitors for Water Treatment Systems

The chemical attaches itself to the metallic surface and provides a protective layer reducing the corrosive action. Corrosion inhibitors help to reduce equipment repair costs, improve water quality, conserve energy, lessen waste, and improve safety. Polymer treatments inhibit scale and deposits by working to disperse solids that form in boilers. Scale inhibitors help boiler water maintain pH levels between 10 …

Jan 17, 2020 · There are two ways to add boiler corrosion and scale inhibitors. One is a boiler with a water tank or pool but no economizer. This allows the medicine to be added directly to the tank or pool. The chemical is then sent to the furnace with the water supply system. The other is to use the medicated funnel to directly pour the chemical into the furnace.

PHOSPHONATES – Scale Inhibitors – Bio-Source Inc

Corrosion is most commonly caused by dissolved gases (primarily oxygen and carbon dioxide), low pH, the attack of mechanically stressed areas, and under-deposit attack. To avoid the corrosion of vital (and costly) metal components throughout boiler systems, external treatment of the feedwater is performed in order to remove dissolved oxygen (DO
