Compact Diameter.  Inflates Up To 8 Times For Easy Insertion

Most sizes afford easy placement by one man. Flexibility allows Multi-Flex™ plugs to navigate through small hot tap or branch pipe into large pipeline; then inflate with air or water.

Typically used for plugging or testing of pipelines especially when there is small-restricted access. The Multi-Flex™ plug is the most flexible plug on the market; it has the greatest multi-size range and will conform to almost any pipe configuration. The small-deflated diameter and flexibility allows insertion and removal through a manhole for plugging otherwise inaccessible pipelines. It is also used as a semi permanent valve to isolate hazardous waste spills. Nylon reinforced nitrile outer ply provides a long life and an excellent seal for testing. No shelf rot like rubber plugs. The by-pass allows flow through by pumping or gravity.

High Strength Flexible Materials
Plugs are made from very high strength flexible woven and non-woven materials and have connections for water or air inflation.

Multi-Size Applications
Petersen® Multi-Flex™ plugs may be used in any pipeline larger than the deflated diameter. Allow for some seepage in smaller size pipelines.

By-Pass
The by-pass design allows flow through during repairs. Flow-thru diameters available up to 3" on standard Multi-Flex™ plugs and larger sizes on custom configurations.

Most Sizes Available
Most sizes are available for prompt shipment.

Light Weight
Allows one person insertion for many sizes and applications.

Diver Friendly
Small deflated size allows removal of air for easier insertion under water.

Higher Head Pressure
All inflation pressure is applied to the inside wall of the pipe through the Multi-Flex™ plug. Molded rubber plugs require much of the inflation pressure just to expand the plug.

Flexibility
Deflated Multi-Flex™ plugs easily navigates bends and small openings. A 72" Multi-Flex™ plug may be inserted through a 24" manhole!

Custom Configurations
Custom Flexible and Rigid Plugs have been manufactured for many high temperature and severe chemical applications. Please contact a Petersen engineer to discuss your requirements.

**Inflatable Plug Warning: Maximum head pressures that a pipe plug may hold back can only be estimated. Pressures are influenced by many factors including fluid in the pipe, coefficient of pipeline friction, pressure required to inflate the plug, and the length of the inflated plug. Generally, an inflatable plug inserted fully into pipeline will begin slipping between 50% and 80% of the inflation pressure, but even 50% may be high 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 must 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.
