Product Features
1. Corrosion resistance
PPR pipes and fittings can resistant to most chemical corrosion; it can withstand PH value range 1-14 high concentration of acid and alkali corrosion over a wide temperature range.
2. Installation performance
PPR pipe PPR pipe is light in weight, and the operation installation is easy, which make it available to weld again. It is very important that pipe and pipe fittings can be welded together in seconds with a simple tool. Compared to traditional connection methods it can save 40%~50% of the time.
3. Safety Indicators
The basic component of PPR is carbon and hydrogen which is simple. It keeps in line with food hygiene regulations, non-toxic. If you use PPR pipe, there will no dirt in the inner wall or “secondary water pollution” caused by rust any more.PPR pipe ,green building materials, is more suitable for transporting drinking water.

Advantages of PPR pipe
1. Maximum operating temperature can up to 95℃; it can work in a long term under the condition of 70℃ and 1.0Mpa.
2. PPR pipe density is only 1/8 of metal pipe; pressure resistance strength test is up 5Mpa, with good toughness, impact resistance.
3. Inner diameter of PPR pipe is little bigger than that of pipe fittings, which can ensure not to increase the resistance to fluid flow.
4. Inner wall of PPR pipe is smooth, no rust, no scaling, small fluid resistance
5. PPR pipe has excellent insulation properties, can significantly reduce the vibration and noise caused by the flow of liquid.
6. PPR pipe energy consumption is only 20% of steel pipe; its thermal coefficient is also only 1/200 of steel pipe, reducing heat loss greatly.
7. PPR pipe is poor electrical conductor material, which can avoid galvanic corrosion phenomena.
8. With poor thermal conductivity, PPR pipe can reduce condensation.
9. PPR pipes, fittings are recyclable.

Q:Glass surfaces are negatively charged, and when blood is collected in a clean glass test tube, it clots. Explain this observation.
it doesnt matter if it's glass or plastic. Once exposed to air (oxygen) the blood will clot unless it's been treated with an anticoagulant like EDTA, heparin, or sodium citrate. That's why these test tubes have anti coagulant in them. The tubes themselves can be glass or plastic, it doesn't matter. No anti-coagulant = clot anti-coagulant = no clot.
Q:ive heard this is used in aquariums and whatnot, but what exactly does it do? and what can it be used for?
Airline tubing is the clear, plastic tubes that are used to put air into the tank. Sometimes it's just from an air pump that makes bubbles, sometimes it's actually oxygen. It comes in lots of different sizes, and good pet stores will sell it to you by the foot.
Q:What is that white plastic tube (usually made of wires inside) made of? PVC?
TPEE---- has the elasticity of the rubber and engineering plastics and rubber strength, compared, it has better processing performance and longer service life; compared with the engineering plastics, also has the characteristics of high strength, better flexibility and dynamic mechanical properties.
Q:The iron pipes and plastic pipes, that antifreeze
The hot and cold temperature that the iron pipe is subjected to is much more than that of the plastic pipe. The iron pipe will not be aged and deformed after the cold.
Q:Wire sets, plastic tools, what tools bend?
However, each of the different diameter of the wire pipe should be corresponding to the different pipe bender. That is to say, you have to bend several wires with different diameters to buy Pipes with different specifications.
Q:What's the diameter of the white plastic tube in the kitchen, about 10cm? What should I do if the water leaks?
Electrode welding: buy several PVC welding electrodes to the building materials shop or hardware city, and weld the welding rod to dew point with hot blast welding torch.The above two methods must first wipe the dew point, no water, and within 12 hours after the repair and repair, the water pipe shall not be used.
Q:looks like its for air bubbles, etcwhat do i need to do with it, hook it up with, etc?thanks all
That's there so you can hook it to an air pump and make it bubble if you wish. MM
Q:I remember having it as a kid and am wanting it for some stocking fillers! cant for the life of me remember what its called. have looked up all kinds of things on the net and not found a thing!
Bloonies! lol this stuff is awesome, the smell just makes you wanna pass out.
Q:Also when a cell is hypertonic to its environment does that mean the environment is hypotonic to the cell?
If the tube shrinks, water must be going out of the tube, and this must be occurring because there is a concentration gradient across the tubing. However, both sides start with distilled water, so the water on both sides should have the same (low) amount of dissolved substances. Presumably the shrinkage is occurring over a period of hours or days? My guess would be that something is getting into the water in the cup - this could be dissolved matter from floating dust or bacteria, but more likely are gases from the air. Distilling water would degas it - oxygen, nitrogen, and CO2 would be removed. However, these gases, most significantly CO2, will redissolve in the water if it is left in air (carbon dioxide dissolves to make a solution of carbonic acid). In addition, any contaminants that persisted through the distillation would be concentrated when the cup water evaporates, though this is likely to be a small change due to the high purity of distilled water. You are correct about your second question.
Q:I'm on vacation right now with my family. I'm on my period and we're going swimming. All I brought was pads. Yesterday I forgot to wear one because earlier in the month it came really light and I figured that was it. But yesterday it went through my pants and came on full force. I don't think anyone noticed but I decided I needed to wear a tampon in my swim suit instead of a pad to be safe. So I found some in the cabinet. I put it in correctly and I'm currently in the car going to the lake. But the tampon is sitting inside me with the plastic tube in it and I can feel it it doesn't hurt but I can feel it. I removed the first plastic cover but there's another one? And it wouldn't easily come off so idk? It's tampax pearls and I'm nervous, I've always worn pads and not tampons.
Did you read the instructions? When you put in the tampon you put it in the push on the skinny stick part to get the tampon out of the applicator. Then you pull the applicator out and just the tampon will be inside you.
