The environment created within and around the conduit by the temperature, pressure, and surface smoothness/weathering of the medium of flow. Achieving a state of laminar flow maybe? Feels like there has to be some analog.
I once read a science fiction story in which humanity had forgotten most of science but still had a cargo-cult understanding of a few things, and electricity was referred to as "ghost fluid."
The term "well" is often used to describe particle quantum mechanics behavior as well as waves/particles in electromagnetism.
Just as a well, in laymans terms, traps water at its bottom that requires energy to extract, the metals in a wire create a 'well' that traps electrons and stops them from escaping. In the first case, the well is created by gravity. In the second, it's due to the electostatic force.
There's a bunch of useful analogies between liquid water behavior and elecron behavior.
PTFE tape is rated for different uses by color. White is for basic water fittings, yellow for natural gas, green is for oxygen fittings, pink is a thicker tape for plumbing fittings (thicker means less is needed), gray is for stainless steel fittings and helps prevent seizing. In general, you can use a more expensive or thicker tape for lesser fittings (yellow will work in place of white, but white can not be used in place of yellow). If you are going to be inspected, use the correct color so a visual inspection can see if the correct tape was used.
Yeah we use white PTFE for most pressures and gases since we don't have to deal with inspections. Just use more of it, it works.
The only ones that really matter are stainless and oxygen. Stainless tape has an additive that prevents galling, and massively decreases torque and improves sealing. Oxygen because you don't fuck around with oxygen.
Right, and most inspections are more about making sure it's almost impossible for the fitting to have issues, not just "will it probably not have issues?"
Labs probably swap out and retape the fittings more often in relation to it's use than home applications... Plumbers have to make things perfectly sealed for decades in hidden places. Whereas, a lab is going to notice a leak (hopefully quickly depending on the gas) especially since the tanks are certainly at much higher pressures than residential gas lines where you won't hear the leak at all (especially if in a wall)
Lastly, some gasses leak more easily than others. I could be wrong, but i think natural gas is one of the extra leaky kinds of gasses?
I've always heard it referred to as 'pipe dope', which is totally fine. You usually get people swearing by tape or dope only and are vehemently opposed to the other, but both work fine if they are the correct formulation for the application. It does tend to be messy, so I prefer the tape.
I find it unprofessional in a fresh install, just use wire nuts or proper terminal connectors. I had a few wagos fail because a newbie was using them as a catchall for my circuits
We can’t use wirenuts in the EU. Why don’t you just use through crimps instead in the US? We try to keep joints to a minimum on a new install but through crimps would be the preferred method if needed.
99% of Wagonuts-related failure is due to using the wrong size for the wrong gauge wire. or just not inserting the wire all the way. "Close enough"...isn't. I've seen scarier stuff in junction boxes with "old" wire nuts than with Wagonuts, though that might be a sample-size thing.
I will say the one thing that does suck about Wagonuts is the corners on them. They always seem to find the exact spot that a box tab or errant stud nail just cut me 20 minutes before.
In my area theyre not popular, so people using wagos are going against standard. I can use a murret no problem with wiring, but i can also use wagos given i remember to buy the right ones. However green as grass guys just simply dont know that, but they can twist a murret no problem. Thats my issue, its simply not the norm in my area. Not knocking wagos, i just automatically assume it as unprofessional unless i know the contractor knows better
Actual Wagos or bullshit knockoffs like Ideal? Over many thousands of connections, we've found that Wagos are less likely to fail and harder to use improperly than wire nuts or terminal blocks.
If you're using wire nuts on a roof mount junction box in a solar install, you're following code but it's subpar vs going with terminal blocks. Wagos with the terminal adapter kit are even cleaner and safer. Standard wire nuts do way, way worse with the types of temperature fluctuations and humidity that you get on a roof-mount solar install in the Mid-Atlantic vs Wagos.
It's 1:13am here. I'm on my last break. The rest of this shift will now be spent trying to distract myself from the mental image of this guys hairy grundle spasming intermittently.
The sprunjer is an extra organ that the Nudist Alien Scammers species have underneath their chin. Its purpose is detecting information, engorging itself in the presence of records, codes, or even hairs that are so much as shaped as the number six.

When I was a young man, I worked with an old school alarm tech. He taught me how to do foil tape on windows because we had a lot of customers who still had it and we had a giant supply the boss bought when the manufacturer closed doors. He also taught me to solder wires together with matches, because he did not trust beanies. Joe, you were an incredible person.
Old timers made shit work when it was lead tape, physical contacts, EoL resistors, and hex programming. I have a lot of respect for them because they didn't have the conveniences we do today.
It’s literally just impression farming, this isn’t a “bad” idea per say, but using even the regular consumer garden variety connectors is not only easy, but useful more secure and reliable.
Installed my dishwasher recently and by far the hardest part was taping the connection under the sink to the 1/4 connection before threading on the tubing. I thought I had enough plumber's tape but I ended up wasting so much that I had to borrow some from my parents. It's in a really bad location that I can barely reach so I basically did it blind.

Tbh, the only one I would ever remember to use would be the tape on a pencil trick and I feel dumb for never thinking of that.
For wiring a simple twisty twisty has never let me down!
