Sealing Disc

The Sealing Disc is a critical component in pipeline pigging systems, designed to create an effective seal between the pig and the internal wall of the pipeline. This sealing action maintains the required pressure differential that drives the pig through the line while preventing product bypass. As it travels, the disc helps remove deposits and debris from the pipe wall, supports product separation during batching operations, and keeps the pig properly centered for stable performance. Its optimized design also reduces flow turbulence, resulting in smoother operation and improved overall pigging efficiency.
