For most size, pressure, chemical, and temperature requirements
Quickly Block the Flow without depressurizing the pipeline!
Petersen’s PeteStop® 128-Series Line Stop is our patented inflatable line stop systems developed to be a far more economical and effective solutions for isolating pressurized pipelines. The small tap hole requires of any PeteStop® plug, reduces equipment size, setup time, and overall project risk.
Key Advantages of PeteStop® 128-Series Pipe Plug Systems:
- Faster – Smaller, lighter equipment speeds up installation and removal.
- Lower Costs – Reduced tap hole size and smaller equipment mean less time and expense.
- Enhanced Safety – Smallest tap hole and larger plug surface area reduce stress on the pipe.
- Lower Environmental Risk – Minimal tap hole lowers potential leakage points.
- Handles Abnormal Pipe Conditions – Works in heavy corrosion, out-of-round pipe, weld beads, and more.
- Versatile – Meets most size, pressure, chemical, and temperature requirements.
- Effective in Tight Spaces – Designed for limited work environments.
- Minimal Seal Pressure Needed – Seals securely inside the pipe with low inflation pressure.
- Reusable – Constructed with heavyweight industrial ballistic nylon reinforced polyurethane (Kevlar, Nitrile, EPDM, Viton, and other options available).
- Superior Pipe Conformance – Adapts better to irregular pipe surfaces.
- Gentle on Aging or Compromised Pipe – Less stress compared to mechanical stops.
- Works Alongside Mechanical Stops – Ideal as a complement when a mechanical seal isn’t possible.
- Over 100 years of pipeline plugging experience.
- Made in the USA
