Double Block And Bleed Inflatable Pipe Plugs

This video shows the versatility of the Petersen Multi-Flex Inflatable Pipe Plugs using the 115-Series and 114-Series in a double block and bleed setup. When inflating between the plugs with gas or liquid, this is typically higher than pipe pressure to act as a seal. Or use the space between the plugs to bleed off any product bleed by or pump the product out.
