Additional Information Additional Information
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.
Custom Configurations Custom Configurations
Custom Flexible and Rigid Plugs have been manufactured for many high temperature and severe chemical applications.May not provide a perfect seal for pipeline testing without customization
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 72â Multi-Flex⢠plug may be inserted through a 10â 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.
Inflatable Plug Warning 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 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.
