FDQ Series Plugging Heads & Drives

Summary:

The FDQ Series Plugging Drive is the core equipment for pipeline isolation operations. It serves as the power source for the plugging head, precisely positioning it inside the pipeline to block flows across various pipe diameters. Ideal for non-stop maintenance on pressurized pipelines, it safely handles flammable, explosive, toxic, or hazardous media—including crude oil, chemicals, LPG, gas, and natural gas—as well as municipal water and heating systems.
