Seawater Pump Protection in a Nuclear Plant.

A nuclear power plant in Zhejiang Province, China, the casing of a recycling seawater pump suffered severe corrosion and pitting from extended exposure to harsh marine conditions. This deterioration compromised the pump’s operational efficiency and reliability, highlighting the urgent need for a durable protection solution to restore its functionality and prevent further damage.
The customer required a long-term repair approach that could withstand the plant’s challenging environment while ensuring reliable, ongoing performance.

Resimac’s Seawater Pump Protection Solution for Nuclear Plants.

Fill corrosion holes and pitted areas with 201 Ceramic Repair Paste.
Apply two coats of 202 Ceramic Repair Fluid for abrasion and corrosion resistance.

Application Details Marine Seawater Pump Refurbishment Solution:

The internal and external surfaces of the marine seawater pump were abrasive blasted to create a 75-micron surface profile. Damaged internal pitted steel areas were rebuilt using Resimac 201 Ceramic Repair Paste, which was applied to repair and restore the affected sections. After the repair, two coats of Resimac 202 Ceramic Repair Fluid were brushed onto the internal surfaces, each with a nominal thickness of 350 microns, offering strong abrasion resistance. To protect against external corrosion, two coats of Resimac 501 CRSG were applied to the pump’s exterior, providing durable protection in demanding marine environments.
