Many of us have also heard about terms like, Hot Tapping and Line Stopping, however, we don’t seem to know these processes in detail, and the difference between the two. In the content below, I have tried to describe both the processes in detail and also the difference between the two so that you could have a fair idea about these two popular methods. Enjoy your reading!

Hot Tapping

Hot Tapping is also called Under Pressure Drilling. This well-planed process can be carried on almost all types of pipes carrying liquids at high temperatures and under pressure. There is no need for a shutdown. A branch connection is provided to a live pipe. Herein, a short section of pipe is used by the engineer who welds (or fits mechanically) an isolating valve to it. The pipe is then drilled to the optimum size through the valve. Once the drilling is completed, the valve is closed and the drilling equipment removed.

Benefits of Hot Tapping:

• No leakage or loss of flow
• It can be performed on almost all types of pipes, such as Iron and Steel
• No need for shutdown

Line Stopping

Line stopping process forms a temporary isolation in a live pipe and is an ideal alternative method where a total shutdown is not an option. A bypass can be installed to maintain flow without causing any major disruption to the services. Line stopping can be used on most common pipe materials, such as Steel and Plastics.

Benefits of Line Stopping

• There is little or almost no loss of harmful liquids and gases
• No major disruption to services
• Can be used on almost all common pipelines
• No drain town or backfilling time
• Suited for fire protection, sprinkler systems, and hydrants etc.
