Mobil Vacuoline™ 525 circulating oil helps coiling mill resolve water separability issues on monoblock line*
No demulsibility-related incidents for
5 years

Monoblock line
Coiling mill
Turkey
Situation
A Turkish coiling mill had experienced a series of water demulsibility problems while using a conventional circulating oil in two of its monoblock lines. The demulsibility problems led to excessive lubricant consumption and unscheduled equipment downtime. In an effort to enhance equipment reliability, the company approached ExxonMobil to identify a lubricant solution capable of improving efficiency and preventing downtime.
Recommendation
ExxonMobil engineers recommended switching to Mobil Vacuoline™ 525 circulating oil on one of its monoblock lines. Formulated from high-quality base stocks and a proprietary additive system, Mobil Vacuoline 525 circulating oil is designed to provide superior wettability, extra oil retention and thin film protection against rust and corrosion.
Result
After testing Mobil Vacuoline 525 circulating oil, the lubricant demonstrated exceptional water demulsibility while preventing further rust and corrosion. It also helped reduce lubricant consumption and unscheduled downtime, and improve operational efficiency. Impressed by the lubricant’s performance, the mill decided to transition Mobil Vacuoline 525 oil onto both lines full time. After five years in service, neither line experienced a single water demulsibility-related incident.
*This success story is based on the experience of a single customer. Actual results can vary depending upon the type of equipment used and its maintenance, operating conditions and environment, and any prior lubricant used.
