Most sizes afford easy placement by one man. Flexibility allows Multi-Size 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 Light duty Multi-size 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. No shelf rot like rubber plugs.
Inflatable Bladders and Inflatable Bungs Features:
Inflatable Bladders made of Natural rubber and covered with Ballistic Nylon.
- High Strength Flexible Materials: Inflatable Bungs are generally made from Ballistic Nylon – many other materials available.
- Multi-Size plugs or Inflatable stoppers may be used in any pipeline larger than the deflated diameter. Allow for some seepage in smaller size pipelines
- Most sizes are available for prompt shipment.
- Light Weight: Allows one person insertion for most sizes and applications.
- Diver Friendly: Inflatable stoppers have 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 Inflatable plug. Molded rubber plugs require much of the inflation pressure just to expand the plug.
- Flexibility: Deflated plug easily navigates bends and small openings. A 72” Multi-Flex™ plug may be inserted through a 7” opening!
- Custom Configurations: Custom Flexible and Rigid Plugs have been manufactured for many high temperature and severe chemical applications.
