what are some cheap materials that can withstand high pressure?

Question

they would have to be able to maintain structural integrity 33yards below water , or deeper, and of course be water proof. no specific price requested just the cheapest you can think of.

Answer 1

PVC pipe is usually cheap and readily available. It is designed to withstand pressure while being waterproof, but I'm not sure what kind of structure you are referring to when you say it needs to maintain integrity. Will this be withstanding forces other than the water pressure on it?

Technically, rocks will withstand water pressure and are free to pick off the ground, but you need to be more specific to other requirements.

Answer 2

33Yd.s depth is about 3 atmospheres, (~ 42 PSI.).
How large a pressure vessel are we talking about.
Small is a lot easier than large.
A material that wil support the pressure on a small vessel will fail as you scale the vessel up in size.
You've got to do the math here.
Total stress on any point will be a function of the pressure on the whole section being considered.
If you're talking about an instrument case, 4" schedule 40 PVC pipe will probably serve.

Answer 3

Kevlar, no need to go for highly woven stuff, just get a mat, and in whatever form you want make a mold, get various layers and fit them together with resin. 5 layers is enough to stand on, a mat of 1m^2 is about 30 bucks. They're not easy to come by, but kevlar is not exactly expensive when it's not tightly woven. Of course, it won't be bullet proof, but it's water tight and able to withstand intense pressure.
People use it with resin to fix their boats, so you know it's water proof, I'm just not sure it'll sink... it's light-weight.

Answer 4

i assume it relies upon on the gun, yet as quickly as I have been to wager i might say it would maximum possibly slot interior the magazine, yet I doubt very lots you need to get it to slot interior the chamber. With each and all of the lawsuits at present i hit upon it demanding to have self assurance it would, yet that would not recommend it won't. With a stable barrel it may be truly an explosion, many times if something is going incorrect and a gun blows up the potential remains going a minimum of generally forward so on an analogous time as nevertheless risky that's not as poor because it sounds (except somebody is to the realm of you and you're able to lose a brilliant form of listening to, my dad has been one million/2 deaf simply by fact that he replace right into a new child from blowing up a gun), with a sparkling gun that may not be the case making it truly risky to the shooter. it would blow anyplace that's the weakest so it must be like maintaining a grenade. i would not attempt to confirm if it chambers in simple terms in case something went incorrect and it fired, some sparkling weapons are noticeably crappy and you do no longer want that factor going off on your hand.

Answer 5

U are dealing with big pressers . Every 33 ft u go down will increase the pressure 1 atmosphere.

Answer 6

Depending on the type of structure and the other requirements, concrete might do the job.

Answer 7

anything plastic or coated metal. 100 feet isn't all that much pressure. You could use a penny.

Answer 8

rocks.
They're so cheap, most of them are free.
And they can withstand such high
pressure, it's really why we invented
GPS, rather than more rocks.
