WHAT IS DOUBLE BLOCK AND BLEED?

Double block and bleed (DBB) is the practice of shutting in a section of pipe on both sides of the valve rather than just one.

It means you close the ball valves to block both the upstream and downstream sides of your working area, and then bleed any pressure that remains in the piping and valve.

The practice of double block and bleed reduces the risks of harm to people and the environment, which is why many oil and gas companies have adopted the practice as mandatory when working on field equipment.
