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.

Advantages and disadvantages of PPR pipes

The full name of PP-R pipes with an international level of new energy-saving plastic products in the nineties is the random copolymer polypropylene piping. PPR installation and use of the advantages and disadvantages are as follows:
Advantages:
1. Harmless to human health, to all ions in water and chemicals in the building are no chemical reaction, compared with metal pipes do not rust,
plastic water pipe will not corrode, and has a high degree of acid resistance and chloride resistance.
2. Belonging to the sustainable development green products. There is no environmental pollution in the process of production, construction and use. Secondary recovery can be repeatedly used.
3. Are different, homogeneous melt PP-R pipe is connected with other pipeline is the biggest advantage of this pipe system. Pipe connections disclose rate is very low, no maintenance, usable visual inspection, the joint firm could no corrode.
4. Light weight, easy handling construction, can greatly reduce the labor intensity, fast construction progress.
5. Good heat resistance: instant use temperature can reach 95 degrees. Long-term use at work pressure does not exceed 0.6Mpa, temperature up to 70 degrees. To meet the general needs of life and production of hot water, it is an ideal hot water pipe.
6. Low thermal conductivity: thermal conductivity of 20 degrees was 0.23 ~ 0.24W / Mk, much smaller than steel and copper. Used in air conditioning or hot water supply and drainage, you can save the investment in the pipeline insulation.
7. Elastic modulus is small: stress due to temperature change is small, suitable for direct burial, in-wall and floor surface layer Concealed way. With High-grade appearance, it is a trend of fashion.
8. Small pipe resistance: pipe wall smooth, non-furring, small head loss, head loss is smaller than the metal pipe; the local head loss is also smaller than the metal tube.
9. Performance can be repaired pipeline: full advantage of PP-R pipe hot melt, the use of PP-R of the eye of a needle stick fill holes in the pipeline repair can also be cut out the damaged pipe replacement pipe.

Disadvantages:
1. Higher cost: With the continuous promotion of the pipe is now ready to accept the price, but the price is still too high, pipe fittings, because one mold imports; Second, copper and stainless steel fittings materials pipe fittings are used in special requests these metals temperature coefficient and accessories for a temperature coefficient of PP-R materials strict consensus, now also need foreign imports.
2. PPR size is only a small outer diameter of 20-110 mm diameter products; types of fittings and valves missing, there is connected to the metal valves inconvenient questions.
3. Rigidity and impact resistance worse than metal pipes.
4. Larger coefficient of linear expansion, for surface or overhead required to lay more pipe hangers, affect the appearance.
5. Construction equipment advanced complex, construction technology requirements, construction workers and construction quality management requirements high. Joint quality and temperature of the hot melt connection, heating time, the seam stress-related, construction prone to bias.
6. UV resistance is poor, in the long sunlight easy to aging.
7. PP-R pipe belonging to combustible materials, it cannot be used for fire water supply system.

Q:What is Dialysis Tubing?
With dialysis you create a blood loop by sticking two needles in the patient (or use two central catheter lumen). The blood goes out of the patient through one needle, THROUGH A SERIES OF TUBING, through the dialyzer (artificial kidney filter), and then through MORE TUBING, and back through the second needle to complete the loop.
Q:how we can design a simple total head tube ??
Your supposition isn't splendid for a standard venturi. If the venturi is pushed (enable's say it relatively is a steam jet) then the rationalization fluid components ability that will boost the entire head on the region you point out.
Q:What are X-ray specs and Wonder tubes?
X-Ray Specs are an American novelty item, purported to allow the user to see through or into solid objects. In reality the glasses merely create an optical illusion; no X-rays are involved. The current version is sold under the name X-Ray Spex; an essentially identical product is sold under the name X-Ray Gogs. X-Ray Specs consist of an outsized pair of glasses with plastic frames and white cardboard lenses printed with concentric red circles, and emblazoned with the legend X-RAY VISION. The lenses consist of two layers of cardboard with a small hole about 6 mm (.25 inch) in diameter punched through both layers. The user views objects through the holes. A feather is embedded between the layers of each lens. The vanes of the feathers are so close together that light is diffracted, causing the user to receive two slightly offset images. For instance, one would see two offset images of the pencil. Where the images overlap, a darker image is obtained, supposedly giving the illusion that one is seeing the graphite embedded within the body of the pencil. As may be imagined, the illusion is not particularly sustainable. What's a Wonder Tube? you wonder? It's a plastic tube with a screw-on cap... but that isn't important. A Wonder Tube? is full of wonder! It's the most wonderous Wonder Tube? known to mankind! The more you look at it, the more creative, wonderful uses you will find for it. We even include an Idea Sheet with a gazillion (okay, maybe a few dozen) ideas to help get you wondering... Product Size: 1 diameter x 5-3/4 long These giant plastic test tubes are virtually indestructible test tubes! Grow plants, observe critters, capture a crystal-like rainbow, or make a wave bottle. Use your imagination, and you will discover dozens of uses for these giant test tubes! These plastic test tubes can be used again and again and will last for years. Children find the most interesting ways to play with these bottles - they are a great open-ended toy for experimentation.
Q:i connected a plastic tube about 7 or 8 inchs long onto a butane can im wondering if when i push down on the can and put a match near it can the fire go back into the can and make the can explode and if so how can i stop that from happening and y would it happened
The fire in this case is a reaction between butane from the can and oxygen from the air. If either one is missing, there can be no fire. The fire cannot propagate back up the tube, since the tube will be filled with pure butane, meaning there will be no oxygen in the tube.
Q:plz answer this question its for school
Ok friend, according my little knowledge, the plastic is better in transporting some kinds of liquids(eg. Water, oil, etc). Why? We've known that water(H2O) is containing Hydrogen and Oxgen elements. The Oxygen can risk some metal (called corosi), the metal will be damaged and doesn't good for a long time.. Plastic? It's not like metal. Good for it.. Thanks,
Q:the tubes are bout 1cm ID with only about a 1mm thickness. I don't think threading them will be possible, and the seal between that has to be water tight.
you need coupling or socket to connect the two pieces and then apply adhesive to connect, there is a traditional way which you heat up on side to form a spigot or cone shape little wider than 1cm and insert one end while it is hot then press for tightness, this is not good from quality point of view.
Q:My bridge had broken and I got someone to make me a new one, but when I reviewed it over, I noticed they moved the plastic tube to the bottom of the violin. Should I not worry about it or have someone fix it?
Does the bridge have a protective cover glued to it under the string - it's called a parchment? Or does the bridge have an insert in it, usually made from Ebony? If either of these is a yes, you don't need the tube. If the answer was no to both, the tube should probably be there to protect the bridge from the string cutting in. Here is a pic of the two possibilities I've mentioned.
Q:What kind of pipe material does the building PPR pipe belong to? Is it a plastic tube or a composite pipe?
PP-R tube is also called type three polypropylene pipe. It is made of random copolymerized polypropylene and is extruded into tube. The injection is made into pipe fittings. It is a new plastic pipe developed and applied in Europe in the early 90s.
Q:PR plastic tubes, everyone said, permanent, a great harm to health, even drinking water is a problem?
According to the main characteristics of PPR pipe, it is non-toxic and sanitary. PP-R has only carbon and hydrogen elements and no harmful toxic elements. It is hygienic and reliable. It is used not only for hot and cold water pipelines, but also for clean drinking water systems.
Q:It seems to me that if this country is serious about environmental issues, we should not be packaging products in anything that cannot be recycled. The world is becoming one big garbage dump!
All plastics can be recycled - as long as there is a recycling facility capable of recycling them. Plastics do degrade each time they are recycled, but they can serve many uses. We need to purchase those items that can be recycled where we live, this forces the companies making the items to use recyclable materials. Certain facilities can only recycle certain types of plastics, usually the ones they can make a profit from. For example, it is not cost effective to fill a semi with styrofoam from Michigan for processing in Florida or California, one of the few places where it is recycled.
