113 through 129 series Multi-Flex™ Inflatable Pipe Plugs and
Packer Carriers For All pipe sizes and shapes
|
|
These Multi-Flex™ Plugs come in various configurations and
pressure ratings. They are the most flexible plugs on the market
with the greatest multi-size range. They conform to almost any pipe
configuration and can fit through very confined spaces. As an
example the 113 series 90” plug will deflate down to only 9”! The
very small-deflated diameter and flexibility allows insertion and
removal through a manhole or a live hot tap for plugging otherwise
inaccessible pipelines.
The Multi-Flex™ Plug may be used in a pipe smaller than the
maximum rated inflation diameter. Since a minimal inflation pressure
with water, air or other inert gas will expand the plug to its full
diameter, most of the pressure is available to seal and lock the
plug in place. The Multi-Flex™ Plug will generally conform to almost
any pipe configuration. Because of the
flexibility these plugs may not always make a perfect seal for
testing especially in a pipe size smaller than the maximum. The
Multi-Flex™ Plugs may be inflated with air, water, or nitrogen and
are available with or without a flow-thru by-pass.
Plug Selection: Contractors may use the 113 or 154 series plugs for isolation, however both plug types have a woven fabric outer cover so do not make a perfect seal. A weld and work area should always be monitored for seepage past the plug but with a fabric outer ply the area may need to be flooded with air or an inert gas to dilute any toxic or flammable gas present. The 114 through 129 series Multi-Flex plugs have an elastomeric outer surface that may be customized for specific chemical resistance and allow less seepage. The molded rubber plugs with an item number beginning with 13 make a much better seal but are made from SBR rubber so not hydrocarbon resistant. NEVER use any inflatable plug as the only means of protection for personnel working downstream. Please select and use the plug best applicable for your application.
These Plugs may be customized for most pressure, chemical, and temperature requirements.
