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:What are the little plastic tubes for in my nail/screw kit for? I know they go in the wall also, but how?
I think you mean the anchors. They are used when your wall is plasterboard and you can't find a stud to screw/nail into. Putting just a metal screw into plasterboard does not have much strenght for hanging things. The plastic anchor helps spread out the load.
Q:What's the plastic pipe that the street lamp foundation is exposed to?
The elevation of the luminaire 1, the elevation of the luminaire, the width of the street and the light distribution curve of the luminaire shall be determined, and the elevation of each street shall be the same. 2, the lamp can be adjusted, should make the light falls on the center line of wide range of L/3-1/2. 3, on the long arm lamp (or arm lamp) after the installation of the lamp body, the lamp head side should be 100 mm higher than the side of the pole. 4, special lamps should be based on the light curve to determine the elevation of the lamp.
Q:Is the electric pipe used with steel pipe and PVC pipe?
When the electric wire pipe is laid, the steel pipe can be adopted, or the plastic pipe can be adopted, but the steel tube must not be used in the ceiling. The standard explanation is for rat bite.
Q:My dip stick broke but i can still see it in the tube, it broke off from the plastic peice.?
try using something magnetic to get it, maybe a small magnet on a piece of string. Sometimes also the dipstick tube can be unscrewed from the block..
Q:Water supply and drainage design, drainage, cast iron pipes and plastic pipes how to connect ah?
Cast iron drainage pipe as a real industry, is the reform and opening up only after the rise. At that time, China's infrastructure construction is vigorous and vigorous, and the urban appearance is changing with each passing day. The drainage pipe material is used in large quantities.
Q:How can I connect varying degrees (sizes) of tubing?
It might help to know what kind of tubing you are working with (both ends). For metal there are various size reducers (flared and threaded). For rubber there are probably push on reducers, plastic may be a bit more difficult.
Q:How do you manually level a mobile home with clear plastic tubing?
This is a very good way to level things over long distances. You do not necessarily need the red drink mix, but food coloring may work better to help see the liquid level. What you would do is set one of the corners of your mobile to where you want it. Next hold the tubing with water inside it so that the water level is even with the bottom of this corner you just set. have a friend take the other end of tubing to another corner of the mobile home and raise or lower the trailer so that the bottom of their corner is also at the top of the water level. you can continue this with each corner until the whole mobile home is level.
Q:theres a game, it's a plastic tube filled with beads and they're objects in it and you shake it 2 find them?
Bumble not find penny..
Q:Does the plastic tube in your subwoofer box matter on the bass?
Yes. The plastic tube is called a 'Port'. Its length and diameter are calculated to allow the speaker enclosure to breathe correctly. When music is playing, the speaker travels outwardly AND inwardly. When it moves it compresses air in the box. The compressed air actually restricts the movement of the speaker cone. This will affect the speakers response, especially at sub frequencies. So, the tube is designed to allow air to escape from the box thereby limiting air compression in the box. They are tuned to both the speaker and the box. If you remove the tube you can expect to hear undesirable speaker 'Waffling at high volume levels. Experiment for yourself. Remember, you may not notice much difference at low volume levels. Once you increase the volume and get the box really working, you will definitely notice a difference.
Q:how do i safely clean the inside of used fluorescent tubes in order to use them for a different purpose.?
Don't do this. The glass is fragile and easily shattered. It contains mercury - not nice stuff to deal with. Get glass tubing or plastic tubing instead.
