128 Series Multi-Flex™ Hot Tap Insertion Plugs Sizes: 2" to 96"

Compact Diameter Allows Insertion Through a Small Hot Tap in a Pressurized Pipeline

Petersen Inflatable Multi-Flex Pipe Plug Insertion System installs a plug into a pressurized pipeline without removing pressure. This allows for maintenance of pipelines without reducing pressure or emptying the pipeline. There are two Petersen Hot Tap Insertion Systems.

The 128 Series Multi-Flex Plug requires a smaller hot tap size and is installed down stream of the hot tap. This allows the plug launching system to also bypass flow upstream of the plug. The 129 Series Plug can be built for much higher pressures than the 128 series but requires a somewhat larger hot tap and inflates immediately below the hot tap. When the project is complete a Completion Valve may be installed and the tapping valve removed.

**Inflatable Plug Warning: Maximum head pressures that a pipe plug may restrain can only be estimated. Slippage is influenced by many factors including fluid in the pipe, coefficient of pipeline friction, pressure required to inflate the plug, and accuracy of pressure gauges. Generally, a Multi-Flex™ Inflatable Plug inserted fully into pipeline will begin slipping between 50% and 80% of the inflation pressure if it has an inflated pipe contact length of 1 ½ to 2 times the diameter, but even a head of 50% of the inflation pressure may cause slippage with some liquids. The inflation pressure is also subject to temperature change and debris or protrusions in the pipeline that could rupture the plug. The inflation pressure should be monitored and plugs anchored and/or mechanically blocked when slippage may cause property damage or injury.  NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system. NEVER use an inflatable plug when its failure would cause injury.
