Case History #504: High-Temp Coating for Oil Cooler Corrosion

June 29, 2021

A heavy equipment producer found corrosion inside carbon steel oil coolers during a six-month preventative maintenance check. The cooler manufacturer was able to reduce corrosion by switching to stainless steel but found that this significantly increased manufacturing costs. They decided to see if they could revert to carbon steel by internally coating the coolers with a high-temperature protective coating: VpCI®-371.

The new coated coolers were sent off for testing, and no corrosion was found at the six-month preventative maintenance check. The heavy equipment producer therefore agreed to specify VpCI®-371 and carbon steel for use in future oil coolers, helping the cooler manufacturer significantly reduce costs while providing the corrosion protection required.
