What Happens When a Pressure Plug Blows Off at 1000 Bar?

I may have commented as such before but I must reiterate that I truly enjoy this kind of content that takes a real world part and illustrates how it fails. Crushing random things is fun and all but there is very little to learn from it, this is different.

If you wanto ro need to try the steel plugs again, try turning down the peaks of the threads, but leaving the full length threaded. Maybe in 200 or so micron cuts. The thread failure will be more abrupt because all of the threads have to fail for one of the threads to fail. By varying onlly the length of the thread as you did the failure mode is differnet depending on whether it is the partial thrad on the plug that fails, or the partially engauged thread in the bung ID. In the latter case, the remaining intact threads in the bung ID have to fail sequentially, not simultaneously; significantly increasing the acra under the curve by extending the time axis.

[@Adreitz7]

I'd suggest turning them down conically, so that the "outer" thread (nearest the head of the plug) needs to give and will encourage the inner threads, at a smaller diameter, to pull through the damaged opening.

[@robertlapointe4093]

Great content. There is an industrial solution for relieving pressure known as burst discs. These are used to protect equipment, such as chemical reactors, from over-pressure events. They typically have burst pressures accurate to a percent or so of their designed relief pressures and are available in a variety of sizes and pressures. I have used burst discs as small as 1/4", and our plant had some up to 48" in diameter. They are basically thin sheets of metal, often with manufactured score lines, that are held in holders with pipe threads or pipe flanges for connection to the system. I have used discs from several manufacturers, including Fike and Oseco. I recall that Myth-Busters used Oseco brand discs for measuring blast wave over-pressures (fairly large area discs, with low relief pressures). Oseco's standard discs are available in 3/16" to 1" sizes with opening pressures up to 3400 Bar. I was thinking that you could put a holder on your cylinder, add a 1000 or 2000 Bar disc and then have a pipe on the outlet side to act as a barrel for some projectile (metal cylinder, bearing ball, etc.) to create a hydraulic gun (assuming this would be legal in Finland).

[@HydraulicPressChannel]

I thought this earlier today. Just didn't realize that I could use high pressure burst discs for. I have to definitely build one :D I also checked the gun law, they have made a mistake! It says that for guns that are over 6.5mm in caliber and use pressurized GAS need gun license :D Nobody thought that anybody would be stupid enough to build a compressed fluid gun :D Might be world's first? and last one :D

[@robertlapointe4093]

@@HydraulicPressChannel Interesting. The legislators who wrote that law must have believed the bit about liquids being incompressible. I will definitely be looking forward to your results.

[@johumm455]

They are also used on the road in truck tanks (fuel trailer for example). you might get them at the nearest trailer parts store 🙂

[@robertlapointe4093]

@@johumm455 Good thought. Probably used on rail tankers also. Compressed gas and liquefied gas cylinders also use then (often in combination with fusible plugs to relieve pressure if the cylinder is exposed to fire). Might check out your welding supplies store as another source for burst discs.

[@MycontentisgoldJerryGold]

That is similar to the pressure relief panels installed on the intake manifolds of supercharged, nitromethane-fueled Top Fuel dragster engines.

That's actually a really reassuring mode of failure for the plugs with enough threads for them to just crack and release all the pressure in a messy spray rather than an explosive failure.

piping failing under high pressure is one of my favourite destructive thing-behavours. becuz, in industry, if such a pipe fails, a lot of other stuff fails immediately afterwards

[@Adam-nv9zo]

"What happened?" Something happened." 😂 Giant understatement. Great video, as always.

[@jamanjeval]

Make a threaded plug out of soft plastic like Delton and thread it into the fitting first and then screw in the bolt. That way, the plastic will deform and seal the leak without squeezing through the threads but still transmit the pressure to the bolt. This video brings up some interesting questions like how good do different methods of sealing threads work and how do different connections fail.

I was going to say. Bullet Velocity. Very dangerous speed. 308 Muzzle Velocity is around 3000 Feet Per Second. If it could maintain that for two seconds, the bullet would travel over a mile. (5280 ft.)

Use Teflon Tape to seal the thred better 😉

Water under pressure does not store energy but the press frame flexure sure does - like a giant spring.

[@MikkoRantalainen]

You could also cut the brass connector thinner from the outside using the lathe and plug the end totally. When that brakes, the part that's still detached to the cylinder should be easy to remove from the cylinder because it's connected to outside threads.

[@Professional_internet]

How much more dangerous can this press channel become? Lauri: yes.

[@howtorepairpendulumclocks]

Bob didnt even flinch. Top bloke. Just shows how marginal these things are between 'seems perfectly ok' to 'deathly'. Higher tensile steel so the fracture is at a higher level and more explosive when it goes...

[@RyanLane-yb4hu]

I think the brass is a great idea, but I would also put some Teflon thread tape on the threads to help with the leaking. Love the videos.

How about putting a Pack of spring washers pushing the seal. It won't be perfectly tight perhaps, but when it goes, the springs will also push the plug. Edit: disc springs is the correct english for what I meant.

[@jackradzelovage6961]

maybe if you put an o ring groove into it so the seal is always present, but the threads are the only thing holding the whole plug in the cylinder. zero leakage until the threads are fully gone

one thing that may help convincing plugs to fail in more explosive matter would be to use twin o-ring seals at the interface of plug and sacrificial cylinder

[@CosmicEpiphany]

If you could compress water into ice that would be a magical video. I believe it’s possible and I’m sure you know you can get that information from a water phase chart. It would be a first for KZbin.

[@christianfritz6333]

Instead of removing threads drill a hole from the bottom toward the head, then cut a shear line under the head on the lathe equal to the depth of the hole drilled.

[@Satori-d6y]

The virtual space needs an instruction sheet: Log in, Log out. Operations, image importation, how to use dialog. Curious concept!

[@The_Keeper]

I wonder if you could get a better/more reliable launch if instead of threaded bolts, you use pressurefit/interferencefit bolts... A tighter fit would mean more power needed to make it pop, and vice versa.

[@MartysRandomStuff]

The problem here is the threads are not a seal against the pressure. The plug needs to have threads on cap end with a smooth bore + o-ring seal on the cylinder side. The plug holder and plug would be more complicated to machine but then there is no need for tightening or a washer, the water pressure will all be pushing on the threads until they give way.

[@Jeusek]

I was thinking the same thing. Another possibility could be leaving all the threads, but making them shorter by filing them down a bit.

[@tapejara1507]

I hope he nails the physics in the virtual press. it sounds wild.

Could you try it again, but maybe with some teflon pipe tape or similar type of thread sealant to try to build enough pressure to burst the larger plug out?

[@Sparky_D]

"thats not optimal" is such a cool phrase

[@TheBlibo]

You say don't try this at home but you are at home so I think I just might try this at home so all I need is a machine shop so I can make hydraulic cylinders and then pop down to to the supermarket and get a 500 ton press what could be simpler 😂 Keep up the good work

[@redsquirrelftw]

Could be fun to repeat this with all sorts of different materials to see how it reacts. Plastics, wood, maybe even glass.

[@richardmitchell2257]

You need to invite the Slow Mo guys !!!!

[@greatnate29]

Maybe see if you can put the seal on the inside lf the screw instead of the outside? Also maybe if you cut off the treads from the other side it woild have less opportunities to strech before it breaks.

[@randr10]

The way to fix this stretching problem is to take threads off of the other end so you don't have that entire plug stretching and yielding before the threads can let go. Basically just cut the plug shorter.
