For most size, pressure, chemical, and temperature requirements
Quickly Block the Flow without depressurizing the pipeline!
Petersen’s FlowStop® 129-8 Series Line Stop is our patented inflatable flow stop system developed to stop the pipeline flow in isolating pressurized pipelines. The smaller tap hole requires of any FlowStop® plug, reduces equipment size, setup time, and overall project risk.
Stop the Flow while Reducing Time and Cost with Petersen® Inflatable FlowStop® systems. Call Petersen or email to discuss the benefits.
- Safety enhanced and Environmental Risk reduced with smaller hot tap hole to help maintain pipeline integrity.
- Conforms to out of round pipe configurations for better seal than mechanical stops.
- Time and Cost reduced with smaller lighter weight equipment allows and faster deployment.
- High flexibility, small deflated diameter allows installation through much smaller hot tap than much heavier costlier mechanical stops.
- Heavyweight Ballistic Nylon reinforced Polyurethane construction for long term reuse. Materials such as Kevlar and Viton available for most pressure, chemical, and temperature requirements.
- A minimal inflation pressure with water, air or other inert gas will expand the plug thus most of the pressure is applied to pipe ID for sealing.
- Small deflated plug diameter allows flexible insertion through a much smaller hot tap than mechanical Line Stops
- Over 100 years of pipeline plugging experience.
- Made in the USA
FlowStop® Product Instruction Manual 129-8 Series
Note: It is best to stop the flow during the installation of PeteStop® line stops. If not practical the below rule of thumb maximum flow rate seems to be acceptable.
1/2 ft/sec for the 129-0 series standard and high pressure plugs
12 ft/sec for the 129-8 series FlowStop® plugs
