AVT - AVT EZ Valve Install Keeps Work On Track At German Oil Refinery

Refinery operations depend heavily on the continuous performance of heat exchangers, but repairing these components often presents a logistical nightmare when cooling lines cannot be easily isolated. At a major regional crude oil refinery, maintenance teams faced the added complexity of performing repairs on a water cooling line located 15 meters above the ground. Conventional methods that require heavy machinery or extensive system drainage were impractical for such a high-elevation, tight-access environment.

The solution involved utilizing a lightweight insertion valve designed for rapid deployment on live carbon steel pipelines. By employing a specialized end-milling process, a small team was able to install a permanent control point in under two hours without depressurizing the system. This approach minimized the hardware footprint and eliminated the need for complex scaffolding or heavy lifting equipment typically required for traditional valve replacements. Maintaining pressure during the installation ensured that refinery production remained on track. Read the full case study to see how high-elevation valve insertion streamlines industrial maintenance.
