What is the maximum pipe diameter of PP R pipe and PP R aluminum plastic steady state pipe? Are ther

The largest ppr is generally 250, the commonly used is 20-63, followed by 75-110; Pipes are divided into sizes according to diameter, for example, 160 refers to the outer diameter of 160mm - this has relevant national standards, basically all manufacturers are produced according to the standards. The market focus of each manufacturer is different, and the types and ranges of pipes produced by different manufacturers are different, but the reference standards are the same. The difference is quality and quality, as well as service and reputation.

There are many manufacturers below PPR 110, 160, you can ask Shenyang Jiuhao manufacturers (the factory is a good scale manufacturer in the Northeast, the quality of such manufacturers is more reassuring--- of course, ** is also slightly higher), if you are a small amount of use, you can go to the building materials store or building materials mall to buy, but to identify the brand.

In addition, Shenyang Jiuhao seems to also make 110 aluminum-plastic steady state tubes. Also making 110 ppr aluminum-plastic steady-state pipes is Shanghai Akcome.

PPR and PPR aluminum-plastic steady state pipe fittings are PPR joints, which is very convenient, it is recommended that you buy the pipe from which to buy the fittings, so that it is not easy to have problems during installation.

If you need a larger amount, you can send me a message and I can help you introduce.

Generally not that big.

You can ask Jinde Pipe Industry.

Dear, hello, we are glad to serve you, the answer is as follows: PPR plastic aluminum steady state composite pipe national standard wall thickness pipe diameter is outer circle size: 20 25 32 40 50 63 75 90 110 mm; Cold water wall thickness: mm; Cold Water MPA Wall Thickness:

mm；Hot water wall thickness: Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, long service life, etc., and are widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheath, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields. Physical Properties:

In general, random PP copolymers have better flexibility and lower rigidity than PP homopolymers. They also maintain moderate impact strength at temperatures down to 32°F, while their usefulness is limited when temperatures drop to -4°F. The flexural modulus (secant modulus at 1% strain) of the copolymer is in the range of 483 1034 MPa, while that of the homopolymer is in the range of 1034 1379 MPa.

The molecular weight of PP copolymer material has less effect on rigidity than PP homopolymer. The impact strength of a cantilever with a cut is generally in the range of feet-pounds. Chemical Properties:

Random PP copolymer to acids. Alkalis, alcohols, low-boiling hydrocarbon solvents and many organic chemicals are highly resistant. At room temperature, PP copolymers are essentially insoluble in most organic solvents.

Moreover, when exposed to soap, sapon-alkali solution. Aqueous reagents and alcohols do not suffer from environmental stress fracture damage like many other polymers. When in contact with certain chemicals, especially liquid hydrocarbons.

Chlorinated organic compounds and strong oxidizing agents can cause surface cracks or swelling. Non-polar compounds are generally more easily absorbed by polypropylene than polar compounds. Its molecules only contain carbon and hydrogen, and there are no harmful and toxic elements.

Aluminum-plastic pipe is a metal composite pipe, and the advantages of composite metal and plastic are combined.

Moreover, from the perspective of foreign development trajectory, the emergence of aluminum-plastic pipes is to replace plastic pipes.

In which aspect is the specific aluminum-plastic pipe stronger than the plastic pipe, it is not clear in one or two sentences.

There are a few points: 1. The plastic pipe transmits light and oxygen, and the aluminum-plastic pipe does not have an intermediate aluminum layer.

2. The thermal expansion coefficient of aluminum-plastic pipe is only 1 8 of that of plastic pipe.

3. In terms of construction, the aluminum-plastic pipe is not bent, and the structural way is very economical in pipe fittings.

PPR pipes can only be laid straight for construction, while aluminum-plastic pipes can be bent and installed within a certain angle range, not to mention the cost performance.

The alloy aluminum layer of PPR aluminum-plastic composite pipe is close to the inner wall of the pipe, and can be directly hot-welded;

The alloy aluminum layer of the PPR aluminum-plastic steady state tube is close to the outer wall of the tube, and the aluminum layer should be cut off and then hot-melted.

PPR aluminum-plastic composite pipe is referred to as aluminum-plastic pipe (PAP), which is made of polyethylene (PE) or cross-linked polyethylene (PEX) as the inner and outer layer, with a welded aluminum pipe sandwiched in the middle core, and coated with adhesive on the inner and outer surfaces of the aluminum pipe to bond with the plastic layer, and formed by one-time molding or two-molding composite process. Since 92 years, the average annual growth rate of aluminum-plastic pipes in Europe is more than 20%. The growth rate is the highest relative to other pipes used in water systems.

PP-R plastic aluminum steady state pipe is a composite pipe composed of PP-R pipe and aluminum layer. On the basis of keeping the specifications and dimensions of the original PP-R pipe unchanged, it is produced by using hot melt bonding technology to organically bond with aluminum strip with thickness on its outer surface at high temperature, and then covering the left and right PP-R (or PE) protective layers. It has a five-layer structure of polypropylene-glue-aluminum-glue-polypropylene, in which the middle aluminum layer plays a reinforcing role, organically combines PP-R plastic with metal, and has both the flexibility of plastic pipe and the rigidity of metal pipe.

Stable mechanical properties are achieved through the integrated aluminum layer, with higher strength and better high temperature resistance.

PPR aluminum-plastic composite pipe is an aluminum ring at the inner layer point, which can be directly hot-welded.

PPR steady-state tube is the aluminum ring at the outer layer point, and the aluminum layer should be cut off and then hot-melted.

What is the difference between the functions of aluminum-plastic pipes, PE pipes and PP R pipes?

At present, the aluminum-plastic pipes, PE pipes and PP-R pipes commonly used in the home improvement market are also quite different in performance due to different materials and processes.

1. From the point of view of connection, the aluminum-plastic pipe adopts a physical connection, which is simple and convenient, unless the operation is improper, and its safety and reliability are very high. PE and PP-R are hot-melt or electro-fusion jointed, and the process is complex, which is easy to produce stacking defect areas, resulting in stress concentration and affecting the long-term performance of the pipeline. In addition, the local high temperature of the electric fuse can easily promote the degradation of pipeline materials and accelerate the aging of pipes.

2. From the perspective of long-term health performance, the middle aluminum layer of the aluminum-plastic pipe isolates oxygen, which is not easy to lead to the breeding of microorganisms and algae plants, and the general outer layer of PE allows antioxidants to be added, which will not cause water pollution in the inner layer, and the PE pipe and PP-R pipe cannot block oxygen, which can easily lead to the reproduction of microorganisms and algae, affecting the hygiene of drinking water; It also contains a large amount of antioxidants, which is easy to cause water pollution.

3. From the perspective of high temperature resistance, the long-term use temperature specified in the national standard of aluminum-plastic pipe is 95, and the maximum use temperature is 110, which can fully meet the needs of household water; The performance of PE pipes decreases rapidly with the increase of temperature, and is limited to cold water transportation; The long-term service temperature specified in the PP-R national standard is 70, and the maximum service temperature is 95, which has certain limitations in the use of hot water pipes.

4. From the perspective of aging resistance, the molecular structure of the aluminum-plastic tube is stable, the inner and outer layers of PE are separated, and the outer layer is allowed to add enough anti-light and antioxidant stabilizers without affecting the hygiene of the inner layer in contact with water; The molecular structure of PE pipe is stable, but the single-layer structure is not conducive to adding stabilizers, which can easily lead to secondary pollution of water in the pipeline. PP-R tubes contain a large number of unstable tertiary carbon atoms, which are susceptible to aging by light, oxygen and impurities.

Performance; In addition, the local high temperature of the electric fuse can easily promote the degradation of pipeline materials and accelerate the aging of pipes.

3. From the perspective of high temperature resistance, the long-term use temperature specified in the national standard of aluminum-plastic pipe is 95, and the maximum use temperature is 110, which can fully meet the needs of household water; PE pipe with the rise of temperature.

High its performance declines rapidly and is limited to cold water delivery; The long-term service temperature specified in the PP-R national standard is 70, and the maximum service temperature is 95, which has certain limitations in the use of hot water pipes.

4. From the perspective of aging resistance, the molecular structure of the aluminum-plastic tube is stable, the inner and outer layers of PE are separated, and the outer layer is allowed to add enough anti-light and antioxidant stabilizers without affecting the hygiene of the inner layer in contact with water; PE pipes.

The substructure is stable, but the single-layer structure is not conducive to adding stabilizers, which is easy to lead to secondary pollution of the water body in the pipeline. PP-R tubes contain a large number of unstable tertiary carbon atoms, which are susceptible to aging by light, oxygen and impurities.

The advantage of aluminum-plastic pipe is that there is a layer of aluminum layer in the middle, and it does not bend when walking hot water.

PE pipe has good flexibility and can only take cold water, which is suitable for large-diameter buried water supply.

PP-R pipe is corrosion-resistant and high-temperature resistant, and can be used not only as a drinking water pipe but also as a hot water pipe, but the production cost of large-diameter (160 or larger) is too high, and it is only suitable for small-diameter water supply.

PPR lined stainless steel pipe is suitable for high-rise water supply, and this material for home decoration is overkill, and there is no need to waste it. The aluminum-plastic steady state pipe is copied by everyone, and its operation technology requirements are high, and there will be water leakage if there is a slight error. In fact, now high-quality PPR pipes will definitely not be inferior to it.

There's a jargon; "First-tier enterprises make brands, and second-tier enterprises make products. Just like Shanghai's "Shifeng Pipe Industry" is a very good and promising enterprise. Excellent quality and good reputation.

In fact, the product news of Aino Pipe Industry has been introduced in detail, you can take a look.
