whats wrong with PVC ???

You say your a chemical engineer,???  today's pipes more often than not are nowadays plastic for carrying salt water, so your problem dosent exhist.

Firstly, the purer the water, the worse it is to use as a conductor. Mainly, the dissolved conductive elements we find in tapwater increase its conductivity, but are not as effective as say the ones found in saltwater. So, unless you wanted to spend the time and money to dissolve the copper, zinc, lead, and other conductive materials in water that could more easily be ducted into wire, it won't be a good idea.

crack pipes with water?

why not get a pipe from the bottom of the ocean to space and pump water into space to save the sea level rising. a few boats aint gonna help

Currently, the polymer sodium polyacrylate.  It is nicknamed "super slurper" because it can absorb 400-800 times its body weight in water.  Oh yeah, it is used in a variety of applications, including diapers.  Pretty cool, huh?

I would use a length of nichrome wire (see links below) stretched between a couple copper blocks. You could make some sort of pinch block out of the copper and connect a power supply to the copper. (or drill a hole through it with a set screw, tap a hole and us a pan head screw)  You will have to insulate the copper from the rest of the world so you don't short something out.  G-10 (a glass/epoxy resin) makes a good moderately high temperature insulator.  One of the contacts should be fixed and the other allowed to "float" and allow for changes in the length of the wire due to heating.  A spring could be used to provide tension or an air cylinder.  The power supply will depend on the length and diameter wire you choose.  If there is a problem with the electrical contacts heating up, you could run some cooling water through them.  Just drill a hole through it and 1/8 NPT pipe tape both ends.  You can plumb some water to it and it will keep the copper chilled.

I am having a hard time picturing the gaps you are trying to fill, so I'm not sure if my ideas will be helpful.  Perhaps you could try ceramic as an insulator.  It also depends on how long the surface will be exposed to the high temperatures.  If its not too long, perhaps you could use wood that has been soaked overnight in water.\nThe aluminum isn't a bad idea, but perhaps you need thicker aluminum.  Like maybe cut open a few soda cans and flaten the result into a crude sheet of aluminum.  Maybe two or three layers worth would do the trick.\nMaybe some gravel or stones?\nWell, those are just some ideas.  Not sure if any of them will work, but maybe that gives you some things to explore.

Most likely it will need to be stainless steel, and with an NSF approval. Please include more detail in your question for a better answer.

use water with salt spray.

Epoxy resin should work. But if my life depended on it I'd spend whatever it cost on the proper eqipment to be safe.

It depends upon the type of brass, and the environment. Brass and copper are incompatable in sea water. Accelerated corrision will occur due to a galvanic reaction. Corrosion may also occur in a marine atmosphere depending on the type of brass. They are generally compatable in normal industrial atmospheres.

I refer you to ASCE for technical papers regarding the subject; also the pipe sales engineer should have this information readily available to you. If you are a student, contacting a sales engineer personally would be a great real world experience. Find several upvc pipe companies on the net and locate their regional sales engineers.

copper or stainless steel fittings will not be harmed, but aluminium can dissolve in sodium hydroxide, although the rate is small though; you wouldnt see a difference unless your entire sink was made of Al alloy and you used drain cleaner every single day.\n\nceramic/porcelain are also safe as they are enameled.

i think the best water aborsbing material is silica gel
