Updated RFWI registry entry and study method of statement for hot tapping and line stopping for water pipe. Hot 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. procedures can be summarized as follow:
- Hot Tap Saddle or weld nozzle installed, 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.
