Hot Tapping is a technique used to build a branch to a cool water pipe in operation, under pressure and sealing conditions, without removal of water from the pipe or interrupt water flow.

Used when:

• A new branch is to be added to the cool water pipe at work.
  
• Before adding a branch of the cool water pipe, avoid removal of a large amount of liquid from the pipe.
• Add or replace the valve in the cool water pipe at work
• Pipeline intermittent work is required for cold water pipe.
