Hot Tapping Procedure : 

* install the hot tapping fitting (pipe saddle) on the pipeline 
* the block flange plate are attached to the pipe saddle for the pressure test 
* disassemble the block flange plate if no leakage found during the pressure test 
* install the sluice valve and valve opened 
* attach the hot tapping machine to the sluice valve 
* drill through the pipeline automatic 
* drill withdrawn and close the sluice valve .
* remove the hot tapping machine from sluice valve .

Common Applications for hot tapping services include:

* Preventing shutdown
