Hot Tapping

Hot Tapping is a proven method and procedure of accessing a live pipe; if your Business cannot tolerate any downtime or interruption to the day to day running of the Business, this method may be for you, subject to a Site Survey and Risk Assessment.

Hot Tapping, or Pressure Tapping, is the method of making a connection to existing piping or pressure vessels without the interruption of emptying that section of pipe or vessel. This means that a pipe or tank can continue to be in operation whilst maintenance or modifications are being done to it. The process is also used to drain off pressurised casing fluids.

Hot Tapping is also the first procedure in line stopping, where an under-pressure saw is used to make an opening in the pipe, so a line plugging head can be inserted.

This method and procedure must only be carried out by competent and qualified specialist heating engineers and in a controlled environment.

Although Hot Tapping is widely known within the Industry and its specialists, and has been carried out for many years as an accepted method, the general public would not have knowledge or be privy to this method and procedure; it is a highly skilled and specialised procedure.
