PeteStop® Inflatable Line Stop Videos

Why PeteStop®

Petersen® Inflatable Line Stop Pipe Plugs are a new way of looking at pipeline intervention. What was once a major project can be done much faster with smaller equipment, less personnel, lower risk, and huge cost savings over traditional mechanical line stop installations.

The PeteStop® System allows contractors, municipalities, water utilities, pipeline operators, and industrial facilities to isolate live pipelines using a significantly smaller hot tap than traditional mechanical line stopping systems.

Designed for difficult repairs, aging infrastructure, out-of-round pipe, and limited access projects, PeteStop® minimizes equipment size, installation time, and overall project risk while maintaining reliable pipeline isolation.

PeteStop® is customizable for your application such as the 128-Series which has the smallest hot tap, the 129-8 FlowStop® for flow up to 10 ft/second, 129-D for Double Block & Bleed, 129-HP for high pressure pipelines, Off-Center design for limited pipe space, variable temperatures, caustic chemicals, and more.
