Just waited to see if remembering to open the valve was in the instructions!!!.....tapping thru 2 gates a stem and the pipe make for a real bad day .....don't laugh....it's been done more times than u would ever believe!!! Personally, I would have opened that valve before doing anything else....my second check of valve position would have been when I measured cutter travel thru the valve body not outside of it.
I've done about 7 hottaps in my day it's scary when you first light up. the welding inspector ut'ed the pipe(that's to check how thick it is) I asked him to stick around while I first lit up, should of seen the look on his face... he did stay...12 " weldolets took most of the day...... 342 retired.
METAL SAMPLES is the best hot tap tool known to man, we just got it up here for the Arctic Oil lines and it is flawless!!! EVEN IN -50 BELOW !!!!!!!!!!!!!!!!
Yeah it was the kind that have the wire that tucks into a slot on the side of the bit. They suck as the wire usually doesnt come out when you need it too.
+Devo yes but when you practice you don't do it on a live pipe. By the time you do this on a live pipe you should be good enough to not read the instructions.
this seems like such a complex procedure. i didnt notice any torquing and perhaps one measurement taken. how come the flange on the tapping machine has far less bolt holes than the flange on the valve?
Я понимаю что технология отработана, но я бы наверное перестраховался. Сначала испытал место врезки и участок трубопровода, до ближайших задвижек, а потом демонтировал и заваривал шибер.
