Product Description:

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.

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:Is rigid PVC double wall corrugated plastic pipe with HDEP pipe one kind?
It is a hard PVC amorphous thermoplastic resin with certain additives of vinyl chloride monomer after the polymerization and made (such as stabilizers, lubricants, fillers, etc.). But strictly speaking, UPVC is hard PVC, and PVC UPVC is not hard, rigorous and scientific discussion should be UPVC UPVC, which does not contain or use plasticizer, hard PVC containing plasticizers (general formula PVC powder + plasticizer + auxiliary plasticizer stabilizer + + + + class processing aid filler toner)
Q:Wire sets, plastic tools, what tools bend?
There is a tool called spring bender, specially bent PVC wire sets, plastic pipes, sold in the general hardware store, the price is not expensive.
Q:2. Two identical strong magnets are dropped simultaneously by two students into two vertical tubes of the same?
The magnet dropped through the plastic tube. Plastic doesn't conduct electric currents with anywhere near the ability of the copper tube. The magnet dropped through the copper tube will induce a voltage around the loop as per Faraday's law of induction. Such a voltage creates a current through the tube, and that current makes this copper tube act as an electromagnet. This electromagnet will apply a force to the magnet which opposes the gravitational force on the magnet. How do I know it will oppose? Because of conservation of energy. In order for the current dissipating heat in the copper tube (due to the voltage and current combination), the magnetic force MUST do negative work on the falling magnet, such that the magnet does work on the tube as it falls.
Q:Is the diameter of the plastic tube 20mm in diameter 18mm?
The diameter 20mm is the outer diameter, and the 18mm is the inner diameter (Kong Jing), then the plastic tube is (20-18) /2=1mm thick tube. This plastic pipe is available, and many plastics pipe manufacturers should be able to produce.
Q:in your opinions what's the best tube style or plastic cage for a regular golden hamster?
i'm assuming you are trying to declare which you rather choose to have some hamster tubes working during the cage? Sorry if i'm incorrect yet i might only make a lot of loop-dee-loops from one edge of the cage to the different. The cage is only too small however. he will have a tough time. you will get 10-15 gallon glass fish aquariums and use that for a cage. they are able to be exceedingly low-fee looking on the place you purchase it from. you will get a number of the aquariums and get some aquarium covers at Wal-Mart for around $5.00. The aquarium covers incorporate a around disk you are able to punch out and positioned some tubes in. The bite toys might probley help him from chewing on the tubes, yet your hamster comes to a decision what he desires to bite on and whilst. He probley will bite on the tubes slightly however. in the adventure that your apprehensive approximately him chewing the bars of the cord cage there is one answer that particularly some rodent proprietors, professionals, vets, and breeders have informed me. Get a cotton ball and dip it into some white distilled vinegar. Rub it relatively over the bars and the chewing will end for extra or less half-hour. you ought to maintain re-utilising and that does get annoying even though it works! they do no longer purely like the scent of the vinegar and that they shop away. this would not do them any injury as long as you don't get it of their eyes.
Q:The cast iron pipe is broken. Replace it with PVC. How do I change it?
The removal of old pipes into the household, where generally inside or outside the wire connector, can be used for wire connection and PVC pipe, according to the time behind you to determine how to install the pipeline.
Q:Is the water pipe made of stainless steel or plastic pipe?
Stainless steel plumbing, of course! Plastic pipes in the production process, in order to product stability, will add plasticizers, antioxidants and other substances carcinogenic to the human body.
Q:How long does cake/cookie decorating tubes stay good?
as a change of a tubal ligation, you would possibly want to ask about Essure. it isn't invasive like a tubal, in which an incision is made. Essure is done by ability of hysteroscopy by ability of the cervix and coils are placed into the fallopian tubes, causing scar tissue to improve, blockading the tubes, combating %.. The fix era after that is way faster and a lot less painful than a tubal. I choose you each and each of the superb.
Q:people singing with a tube in their mouths?
It's called a Talk Box.
Q:How do you get the last squeezes out of the new plastic tubes?
I take a hair brush or comb and run it on the side to push as much as possible to the top then I cut the tube close to the top and scoop out the rest. I do this with my tubes of makeup too. There is really a lot left in there! I dilute my shampoo with water. It spreads easier and lathers better and works just as well if not better.
