CW pipe, fixing a mechanical fitting
CW pipe, fixing a mechanical fitting
(OP)
Hello all
New subscriber here, I have 4" main Supply/return legs on a CHW system I want to apply clamp on mechanical Tee's to extend to a secondary area (capacity is not a problem) I can turn off the chiller short time but can not drain down, in order to drill the hole for fitting (really quickly) --- I am concerned that whilst drilling through the pipe wall, maybe swarf (metal shavings) and possibly the plug piece itself may fall inside the pipe contaminating the water. Maybe this is crazy but has anyone heard of a "magnetized" diamond hole cutter bit that would prevent this happening (Hole would be 1-1/2") or another option?? appreciate your help.

count on some dirt staying in the pipe and look where it would end up.

I've seen mechanical contractors freeze lines that size. That would allow you to open up the line to insert a tee. Look for "line freezing services"
