The Petersen® Multi-Flex™ Line Stop Plugs are ideal for insertion through a small Hot Tap to stop the flow in a larger pressurized pipeline. Custom configurations are possible for most pressure, temperature, and chemical requirements. Petersen® Plugging Systems are available for small to very large pipelines. Petersen® Multi-Flex™ Plugs are also available with an end inflation port for installing through a riser or manhole. Petersen® Plugs may be inflated with water, air or nitrogen. Petersen also has Hot Tapping tools for up to a 6” tap in any size pipeline. Petersen can provide complete hot tap plugging systems and on-site technical support. Visit our web site www.pipeplug.com and email us at sales@petersen.cc. Call Petersen 1-800-926-1926 for all your pipeline plugging requirements.

**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.
