Something I REALLY don't recommend trying to get high on! Before they invented Teflon tape, a plumber who wanted to seal pipe threads used a liquid sealant. You can still get this and many plumbers prefer it. It comes in a little can with a brush, and you apply it to the threads on the pipe before you screw the pipe into the fitting. It's called "dope" because it can make you dizzy if you inhale the fumes.
No, teflon tape (and pipe dope, for that matter) should never be used on flare fittings. They are designed to seal without tape or dope, and may actually leak if tape or dope is used.
Pipe dope better solution than tape.
TF-15
Pipe that meets the requirements of sour gas service per NACE MR0175.
a pipe fabricator would be a pipefitter that fabricates pipe in a shop or in the field.he/she does this with a welder and a helper.a number of power tools.he takes a set of iso drawings and cuts pipe to length and makes the fittings until he has fabricated what the drawing he has in his hand calls for.they send it to the place it has to be installed at and install it.most times.alterations are made in the field.
If you are screwing in -- yes -- If not -- you do not use pipe dope
No pipe dope is to be used on the brass seats they will seat dry.
pipe dope and teflon tape
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.
no
Pipe dope and/or teflon tape
NO but you will need some type of sealent OR braze or soldering
Joint compound AKA dope is used as a lubricant and to seal minor imperfections of the threads
when joining to lengths of black steel it is necessary to use either Teflon tape or pipe dope, also called leak lock, this is not to seal the joint per say but the tape and doping act as a lubricant on the threads of the joint allowing for the pipe to be turned together tighter also the dope will dry and become a sealant
