Hot Tapping – an alternative to Pipe Freeze

Hot Tap into condenser water pipe

Hot Tap into chilled water pipe

Hot Tap allows branches to be fitted to an existing line without any interruption to existing plant and equipment.

Hot tapping, or pressure tapping, is the method of making a connection to existing piping or pressure vessels without the interrupting or emptying of 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 and add test points or various sensors such as temperature and pressure. Hot taps can range from a ½ inch hole designed for something as simple as quality control testing, up to a 48-inch tap for the installation of a variety of ports, valves, t-sections or other pipes.

Hot Tap Procedures:

  • A hot tap saddle, service saddle or welded threadolet, valve installed, assembly is pressure tested and hot tap machine attached.
  • Valve opened, hot tap completed, coupon or cut portion retained by latches on pilot drill. Pressure is contained within the hot tapping machine.
  • Cutter and coupon retracted and valve closed. Fluid is drained and hot tapping machine is removed. The tapped valve is now ready for the contractor’s tie-in or IFT’s linestop/stopple equipment to be inserted.
