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.

Chemical Structure of PPR

PP random copolymer of ethylene molecules generally contain 1 7% (by weight) and 99-93% (by weight) of propylene molecules. On the polymer chain, ethylene molecules randomly inserted in the middle of the propylene molecules. In such a random or statistical copolymers, the majority (typically 75%) are single molecules of ethylene incorporated into the insert, called the X3 group (three consecutive ethylene [CH2] are sequentially arranged in the main {TodayHot} chain), which can also be seen as an ethylene molecule is inserted in the middle of two propylene molecules.

Another 25% of the ethylene molecule is inserted more incorporated into the main chain, also known as X5 groups, since there are five consecutive methylene groups (two ethylene molecules together two propylene molecules inserted in the middle). It is difficult to distinguish between X5 and higher groups such as X7, X9 and so on. In view of this, the XS and higher ethylene content groups together counted as> X3%.

Randomness ratio X3 / X5 can be measured. When the above percentage X3 group is large, it will significantly reduce the crystallinity of the copolymer, the final properties of this random copolymer influence. Ethylene copolymer has very high levels of crystallinity of the polymer, similar to the effect when high random polypropylene content.

Unlike random copolymer PP homopolymer as the polymer backbone randomly inserted into the ethylene molecules hindered crystalline arrangement of polymer molecules. Copolymers of a decreased change in crystallinity caused by physical properties: PP homopolymer and random copolymer is reduced in rigidity as compared to improve impact resistance, better transparency. Ethylene copolymers also lower melting temperature, which has become in some ways the advantages of their use.
Random copolymer may contain more leather extract and random PP, as well as a much higher ethylene content of the polymer chain. This higher leather extract content may, depending on the polymerization process, to varying degrees in all the goods copolymer materials and meet the Federal Food Administration (FDA) on food contact {HotTag} specified on the cause difficult.

Manufacturing method of PPR pipes:

Ethylene / propylene random copolymer and ethylene molecules is carried out by polymerization of propylene molecules simultaneously obtained, the use of the reactor and the production of PP homopolymer same. Ethylene propylene molecular ratio of small molecules is faster than the reaction (reactive approximately ten times) propylene. This stereospecificity of the catalyst activity is increased and decreased, resulting in increased generation amount of atactic polypropylene. In order to reduce the generation of such random thereof, the reaction temperature needs to be reduced, thereby reducing the activity of the catalyst, and to reduce the content of the final product ppr sizes random isomer, to obtain a product having a more balanced performance.

Ethylene content (> 3%) random copolymer in the production process more difficult to deal with, it is difficult to carry out polymerization in hexane diluent, since the two by-products of the reaction (the amount of atactic polypropylene and ethylene-containing high copolymer) can be dissolved in hexane. This bulk liquid propylene polymerization reaction is the same, in spite of low solubility. Diluted with hexane to produce a large number of process by-product, it must be separated out in hexane in the recycle phase, which will increase the total cost of production, but was able to get close sparingly soluble polymer component of the cleaner. In the bulk polymerization process, these impurities will remain in the polymer, and trouble in handling sheet-like material. Moreover, the final copolymer products contain more soluble impurities. Second washing with an organic solvent, most of the impurities can be removed, but will increase the overall cost of production of the copolymer. In general, a high content of by-products, the flake random copolymer will become more viscous, when the ethylene content higher than 3.5% (by weight), the problem is more prominent.

Q:If you buy them in bulk from the mint, what do they come in?
2006 American Buffalo Gold Proof One Ounce Coin Gold buffalo $800.00 coin? Individual in a case with letter of authenticity. each coin enclosed in hard round plastic and place in a blue case.. very nice and very beautifully.... The American Buffalo Gold Proof Coins are collector versions of the official United States Mint American Buffalo Gold Bullion Coins and are available in limited mintages. The designs are based on the original 1913, Type I Buffalo nickel, as designed by James Earle Fraser. very very sharp proof coin.. This coin is going to be a winner 20 years from now in the market place among collectors.. us mint link and picture catalog.usmint /webapp/wcs/sto...
Q:i am designing something that has a frame of tubing that its relaxed when there is no air pressure in it, but becomes straight and reletivley rigid when when you put air presure in it.
The 2 foot diameter nylon sleeves filled with low pressure air that you see for advertising displays. If you try to use small diameter tubing, with flexible plastic tubing, it won't work. The closest tubing that does work is specially made for pressure gauges, and it just slightly uncoils under pressure.
Q:This will be more efficient since right now the bed covers the vent, just wanted to somehow route the cool air away from under the bed so my roommate won't have to turn the air really cold to cool down at night. Thanks in advance.
Also okorder /..
Q:Hello I want to buy a leather storage tube for my A1 sized drawings. I'm studying architecture and I want something a bit more classy than the plastic tubes I have found. Does anyone know where I can buy one?
Cost Was this what you were looking for?
Q:For some tuning fork frequencies is it possible to hear resonance at more than one length of the plastic tube? Why?
Because the tube might be long enough to reflect the third harmonic( if it is a tube closed at one end ). It is easier to find the 2nd resonance with the higher pitched tuning forks.
Q:and waist, torso of your body, reason why is because i need these materials for building, making a costume for cosplaying, and i'm looking for it in plastic instead of meta
I'm not sure if these are the best solution for you, but... something to consider, at least? Best of luck with your cosplay, in any case! (Is it strange that I'm now really curious what your costume will be? All this tube research has me interested. :y )
Q:i have to know, because otherwise the hoover is rendered completely useless, the bottle cap is the same size as the hoover tube and i do not have a stick or long object long enough with which to poke it out :(please help meunfortunately, the hoover tube is plastic :( regrettably majority of said tube is plastic and flexible...this darned cap! therefore cannot be heated up, as the hoover will melt..and i can't afford another one!so hanything else anyone can suggest would be greatly appreciatedthe cap is stuck quite far up, but in a solid part of the plastic, im not sure blowing would dislodge it as sheer hoover sucking power seems to do nothingHELP PLEASE!
if the hose or tube is strong enough you could bend the cap inside from the outside (similar to bending a beer cap) and it should fall out.. use a coat hanger wire with a hook in the end is another alternative.
Q:I remember big coloring posters, 24 by 36, that come in a plastic tube so you can roll it up and store it. The big posters came with 10 markers you could use on it, but you could use anything you wanted to color it. Where can I buy those now? I can't find them at Walmart anymore, and there's a really small selection on OKorder.
I am not sure of the size but you can find some at Office Depot or Office Max. You can also try a toy store like Toys R Us.
Q:I have a bear hamster she hates cardboard tubes she already has a wheel and a ball and a play pen even a little house dont sugest plastic tubes because i have her in a little fish tank like cage tubes wont work thx
u could buy chew toys because they make sure your hamsters teeth don't overgrow and for some odd reason they like to play with it too. hope it helped:)!!!!!
Q:You find this tubing with home cinema equipment cables. It's mounted on the wall and does not need any wall cable grippers or anything.
ITS A CONDUIT, THEY CAN BE METAL OR PLASTIC.
