An inflatable, spherical device, frequently constructed of rubber or similar flexible material, is employed to obstruct the flow within a pipe or conduit during maintenance, repair, or testing procedures. These devices ensure the integrity of pipeline systems by providing a temporary, secure seal. For instance, during hydrostatic testing, such a device can isolate a section of pipe, enabling engineers to evaluate its structural soundness under pressure.
The use of these sealing mechanisms offers significant advantages in maintaining pipeline infrastructure. They enable localized work without disrupting the entire system, reducing downtime and costs. Historically, these devices have evolved from simple plugs to sophisticated, high-pressure-resistant designs, contributing significantly to safety and efficiency in the water, sewer, and industrial pipeline sectors. This evolution has led to improved accuracy and reliability in leak detection and repair.
