LP Foambag offers a fast, efficient method of shutting down low pressure distribution mains or services for a wide range of maintenance applications including leakage control and pipe abandonment projects.

Unlike any other foam product this 2 part resin system was designed exclusively for use in the natural gas industry. It is deployed inside of a semi-porous fabric bag and remains in close proximity to the injection point.

Once the foam swells to fill the foambag, a limited amount oozes out through the special semi-porous surfaces to roll any fluids, including water, out of the way. It then combines with any liquid or loose debris and bonds to the pipe walls.

The shutdown bag is deployed through an entry hole that is less than one quarter of the diameter of the main, which in the case of cast iron prevents the requirement to use any full encirclement fittings for completion.

The bag controlls the position of the foam so that it is forced rapidly across the main for a full gas shutoff in a few minutes. After waiting 15 minutes the main can be cut and capped on the downstream side of the foam.

• LP Foambag is supplied as a complete kit including the 2-part prepackaged foam system.
• The system facilitates mains shutdowns when used in combination with PLCS Flowstop or Sensor Bags.
• LP Foambag provides sectioning for dead insertion during upgrade projects.
• LP Foambag provides sectioning during Live Mains Insertion projects
• Close tolerance branch main abandonment shutdowns
• Foams offer control of PCBs in abandoned mains.
