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.
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.

Material properties of PPR

PPR Physical properties: generally, the flexibility of the ratio of random PP copolymer is better than that of PP homopolymer, and the rigidity of them are in contrast. When the temperature dropped to 32 ° F, they can maintain moderate impact strength, and when the temperature dropped to -4 ° F, the usefulness will be limited. Flexural modulus (1% secant modulus of strain) of the copolymer is in the range of 483 ~ 1034MPa, and the homopolymer in the range of 1034 ~ 1379MPa. Effect of molecular weight PP copolymer material is not as rigid PP homopolymer large. Izod notched impact strength is generally in the 0.8 to 1.4 foot-pounds / inch.

PPR Chemical properties: PP random copolymer acid. Alkalis, alcohols, low-boiling hydrocarbon solvents and many organic chemicals have a strong resistance. At room temperature, PP copolymers are essentially insoluble in most organic solvents. Moreover, when exposed to soap, lye soap. Aqueous reagent and alcohols, they do not like many other polymers that would occur environmental stress cracking damage. When in contact with certain chemicals, especially liquid hydrocarbons, Chlorinated organic and strong oxidizing agents, can cause surface cracks or swelling. Non-polar compounds are generally easier than the polar compounds absorbed polypropylene. The molecule only carbon, hydrogen, no harmful toxic elements exist.

PPR Barrier properties: PP homopolymer and copolymers have a very low water vapor permeability (0.5 g / cc / 100 square inches / 24 hours). These properties can be improved by orientation. Stretch blow molded polypropylene bottles Yiba resistance to water vapor permeation performance improvement to 0.3, the oxygen permeability of 2500.
PPR Electrical properties: Generally, polypropylene has good electrical properties, including: high dielectric strength, low dielectric constant and low dissipation factor; however, power applications usually selected homopolymer.

PP-R pipe production process is extrusion process, first add PP-R raw material in the hopper by gravity into the extruder in the extruder barrel heated extrusion mixed and fully plasticized from the extruder mouth die extruded into stereotypes, stereotypes of the pipe after by tractor, measured by length, cut by the cutting machine, after passing the test tube after storage. Corresponding pp-r pipes and fittings are produced by injection molding.

Polyethylene pipe production process: PP-R raw materials → vacuum suction hopper send feed storage → extrusion → cooling stereotypes traction → cutting → inspection → warehousing pipe production process: PP-R materials → feeding conveyor → storage hopper feed heating and melting → cooling and molding injection extrusion mold → inspection → warehousing.

Pipe Extrusion parameters: (1) a screw speed of 5 ~ 38r / min (2) barrel temperature profile of 1 to Zone 2 180 ~ 190 3 ~ 4 region 200 ~ 210 mold temperature of 200 traction speed 2 ~ 20m / min Tube injection parameters: 200 ~ 230 front barrel portion (1) cylinder barrel temperature profile 160 ~ 170 rear central cylinder 180 ~ 200 (2) of the nozzle 170 ~ 190 (3) 40 ~ 80 PP molds -R pipe production process defective products, after crushing can be used again, which improves utilization of raw materials, and reduce production costs, improve economic efficiency.

Q:I'm looking for the 12, 16, and 20 plastic flat bottom tubes w/ lids that you see used to make Sandy Candy.?
OKorder might have them. If not, find a candy supply company.
Q:How to mend a hole in a plastic pipe?
A sheet of plastic, the thickness of which is equivalent to the wall of the basin. The material is then sanded with a sand wall and painted with 502 (501) glue. Press it quickly and press it for a few minutes.
Q:Where to purchase plastic resealable tubes ? ?
please go to the near your shopping mall and you find out plastic all kind of tubes.
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:how much fence privacy plastic tubing needed?
Hi I can tell you from experience as a gardener/landscape designer not to plant a tree. First, tree roots and trunk will eventually grow outside of the property line and will be choked up against the fence -- and either the fence or the tree will eventually have to go. Finally, tree trunks aren't actually that good of a screen. The solution: shrubs. There are many many kinds of shrubs, that grow wuickly, and create a dense, brod cover. The are easier to care for longterm than trees, also. Plus, most have lovely flowering seasons. You need to consider your climate as well as sun exposure. Southern exposure may indicate that a dought tolerant plant would be best. Check the bookstore for local choices. Here in the great basin of Nevada, Lilac is often a perfect choice, or also Spyrea (which are also hardy to even the toughest soils like clay). Another thing to remember is to look for non-deciduous species - that means they will keep foliage year-round, so will provide constant privacy.
Q:Vinyl/Plastic tubing idea's?
You can use it as a storm drainage from your house to the main sewer line, you can use it too as false column in your house as additional decoration, can be use as a form of a circular post, can be use as backyard bench.
Q:How long does cake/cookie decorating tubes stay good?
Those tubes you are referring to are icing. I am sure they must have preservatives in them to make them last longer. I think there should be a date on the tube which would say. Best if used by..... I know that with my buttercream icing, which I make at home, It will stay good on the counter top for about 2 weeks. I wouldn't want to eat it after that. If your icing tubes were kept in the freezer you could keep them for a year or more.
Q:On a 2003 mercedes e320 how can I remove the transmission fill tube that has a red plastic pin on the cover? ?
stick a small flat head screw driver underneath the red square plastic part of the lock. pull the screw driver up and break off the red plastic tab. take the screw driver and push the rest of the broken rec lock part down all the way. pull of the black plastic cap. Make sure you pull out the little black o ring with it.
Q:How do I get my hamster to stop chewing on the plastic tubes in his cage?
Plain wood chew toys would give him something to play with (don't get coloured ones as the dye might not be safe). The chewing should be less noisy, but he might still prefer to chew the plastic (make sure he doesn't swallow any as this could give him an intestinal blockage).The alternative is simply to move him in to another room at night; that is safe and solves the problem.
Q:does anyone know where i could buy those long fluorescent tube shots they usually sell at the club?
You mean glow sticks? Dollar store.
