Product Specifications
Additional Information Additional Information
Typically used for plugging of pipelines especially when there is a small-restricted access. This is the most flexible plug on the market; it has the greatest multi-size range and will conform to almost any pipe configuration. A 36" plug will also stopper a 10" pipeline! When completely deflated, a 72" plug will deflate down to only 15"! The very small-deflated diameter and flexibility allows insertion and removal through a manhole for plugging otherwise inaccessible pipelines. It is also used as a semipermanent valve to isolate hazardous waste spills and regulate flow.
Custom Configurations Custom Configurations
Custom Flexible and Rigid Plugs may be manufactured for any shape, high temperature, and severe chemical applications.
Diver Friendly Diver Friendly
Small deflated size allows removal of air for easier insertion under water.
Flexibility Flexibility
Deflated Multi-Flex⢠plug easily navigates bends and small openings. A 72" Multi-Flex⢠plug may be inserted through a 15" opening!
Higher Head Pressure 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.
High Strength Flexible Materials High Strength Flexible Material
Plugs are generally made with Nylon reinforced Nitrile outer ply and have connections for water or air inflation. Many other materials available.
Inflatable Plug Warning 0
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 1/2 to 2 times the diameter, but even a head pressure 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 could 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 could cause injury or catastrophic damage. NEVER use an inflatable plug as the only means of protection for personnel working downstream.
Lightweight Lightweight
Allows one person insertion for most sizes and applications.
Most Sizes Available Most Sizes Available
Standard sizes are generally in stock up to a 48" diameter with larger sizes available in just a few days.
Multi Size Applications Multi Size Applications
Petersen® Multi-Flex⢠plugs may be used in any pipeline larger than the deflated diameter. Some seepage in smaller size pipelines may require a specific size vapor sleeve especially when pressure testing.
