Description
Heavy duty inflatable bladders or Pipe Plugs
Most sizes permit easy placement by one man. Flexibility allows Multi-Size plugs to navigate through small hot tap or branch pipe into large pipeline. Plugs can be inflated with air or water.
Features:
- High Strength Flexible Materials: The heavy duty inflatable bladder is made of Nitrile, which is reinforced by several layers of ballistic nylon outer ply. The bladders offer excellent hydrocarbon resistance – many other materials available and have connections for water or air inflation. Bladders made from Butyl rubber are available. For high puncture resistance and toughness we supply bladders with Kevlar Outer layer. For specific applications we supply different bladder materials such as EPDM or Viton.
- Multi-Size pipe balloons or plugs may be used in any pipeline larger than the deflated diameter. When using plugs in smaller than rated maximum diameter, allow for some seepage.
- Most sizes are available for prompt shipment.
- Light Weight: Allows one person insertion for most sizes and applications.
- Diver Friendly: 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 pipe plug. Molded rubber plugs like the Huntindon Fusion Rubber Plugs require much of the inflation pressure just to expand the plug.
- Flexibility: Deflated Multi-Size plug easily navigates bends and small openings. A 72” Multi-Size plug may be inserted through a 15” opening!
- Custom Configurations: Custom Flexible and Rigid Plugs have been manufactured for many high temperature and severe chemical applications. Kevlar bladders or Butyl rubber bladders are avaialble.
