LK-318 is a high-performance, specialized scale and corrosion inhibitor engineered specifically for the rigorous demands of power plant circulating cooling water systems. Formulated with a synergistic blend of organic phosphonic acid, polycarboxylic acid, and targeted inhibitors for both carbon steel and copper, it provides an industrial-grade shield against mineral buildup and metallic degradation.
Designed for maximum efficiency in complex industrial environments, LK-318 effectively controls the precipitation of calcium carbonate, calcium sulfate, and calcium phosphate. By combining superior chelating properties with powerful dispersing effects, it ensures optimal heat exchange efficiency and extends the operational lifespan of critical infrastructure in petrochemical, steel, and power generation facilities.

Frequently Asked Questions
LK-318 is specifically formulated to handle high-volume circulating cooling water, providing simultaneous protection against scale formation and corrosion for both carbon steel and copper pipes.
It should be added to a dosing barrel, diluted with water, and then continuously injected via a metering pump at the circulation pump inlet or water collection tank outlet.
LK-318 provides superior control over calcium carbonate, calcium sulfate, and calcium phosphate, preventing them from adhering to system surfaces.
As LK-318 is weakly acidic, operators should use personal protective equipment (PPE). In case of skin or eye contact, rinse immediately with clean water.
The generally recommended dosing concentration is between 5-20mg/L, calculated based on the volume of supplementary water entering the system.
Yes, its high efficiency in corrosion and scale inhibition makes it ideal for petrochemical, chemical, and steel industry circulating cooling water systems.
