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:Can the rusty iron pipe be sawed off and connected to the plastic tube?
It depends on the rust of the pipe. It is not weak or serious. The iron pipe is sheathed wire, one end of the pipe is connected with a plastic heat wire connector
Q:What are the requirements for the installation of expansion joints for drainage plastic pipes?
The expansion joint shall be installed near the water junction pipe, such as the drain pipe under the floor. The expansion joint shall be attached below the branch pipe fitting.
Q:I think it may be meth or crack or something? What should I do?
Destroy it and throw it in the garbage DON'T flush it we don't need more crap in the water supply.
Q:Is it possible to use extension tubes with modern nikon camera for macro photography?
Do it all the time.
Q:He was talking about dope before he offered me a smoke, but when he offered me a smoke from his clear plastic tube, I asked what it was, and if I remember right he said Marijuana.He had to use his glasses to push whatever was in it to the end.I had never been high before, my heart was racing, and I was VERY talkative and loud.
Probably Marijuana it sounds like the side effects of a first time user
Q:What sizes are plastic tubes available in?
Plastic tubes are available in a wide range of sizes, varying from small diameters of a few millimeters to larger diameters of several inches.
Q:I know some cages like that are of rather bad quality, and the add ons sometimes fall off and are hard to put back on. So if anybody has owned that cage or one like it, tell me what you think of it. (: Thanks!
I am pretty sure that they can climb it but beware because when it is time to clean the cage it is such a pain to hose those tubes.
Q:Are plastic tubes resistant to UV radiation?
Yes, plastic tubes can be resistant to UV radiation depending on the type of plastic used. Some plastics, like PVC and polyethylene, are naturally resistant to UV radiation while others may require the addition of UV stabilizers to enhance their resistance.
Q:Can plastic tubes be used for architectural installations?
Yes, plastic tubes can be used for architectural installations. Plastic tubes offer versatility in design, durability, and cost-effectiveness, making them suitable for various architectural applications such as structural supports, lighting fixtures, decorative elements, and more. Additionally, plastic tubes can be molded or shaped into different forms, allowing architects to create unique and innovative installations.
Q:Can plastic tubes be used for water filtration systems?
Yes, plastic tubes can be used for water filtration systems. Plastic tubes are commonly used in water filtration systems as they are durable, flexible, and resistant to corrosion. They can efficiently transport water through different stages of filtration, allowing for effective removal of impurities and contaminants.
