Hot Tapping

HOT TAPPING By Vinothkumar Nagaraj Roll no 33 Batch no 32

INTRODUCTION



The ability to safely tie-in to a pressurized system,while under full operating conditions.

Adding new connections to piping is not the only use for hot tapping.Some of the many uses include:  Product sampling point  Pressure control switch installation  Flow meter installation  Inspection of pipe line  Thermo well sensor installation  Determine product in the pipeline  Draining of pipeline  Air relief point

Gate Valve

Drilling or Tapping Assembly

Tee or Butt welded pipe

The hole saw is advanced through the valve,to the pipe.The machine is engaged and the cut begins.When the cut is finished,the machine is disengaged and retracted beyond the gate of the valve. The valve is closed and the machine is removed. Angle Taps, Elbow Tap and taps perpendicular are also possible in this method.

ADVANTAGES No need to shutdown the system for one particular work.  No need of Bypass line  Convenient, no need for massive draining of fluid.  Economical 

DISADVANTAGES High Safety Precaution Required  Skilled Technician Required 
