It is widely used in construction, municipal, industrial, and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power, optical cable sheath, industrial fluid transportation, agricultural irrigation, and other fields.

With the increasing market demand in construction, municipal engineering, water conservancy engineering, agriculture and industry, and other sectors, China's PPR pipe industry has shown rapid development. In 2009, the production volume of plastic pipes was 5.804 million tons, 18.9% year on year. From January to September 2010, the production volume of plastic pipes was 5.528 million tons, increasing 28.23% year on year. At the same time, as consumers continue to improve product quality requirements for environmental protection, health, durability, etc., while the output of plastic pipes in my country has increased, the product quality level has been continuously improved, the technological progress of the industry has been accelerating, and the number of brand-scale enterprises has continued to increase. Varieties of materials and new structures are constantly emerging, advanced system design concepts are emerging one after another, the functionality of products is more apparent, and the application fields are further broadened. Analysis believes that the market share of China's plastic pipes has exceeded 30% of all tubes.

By 2015, plastic pipes will be used for 85% of construction drainage pipes, 80% of construction rainwater drainage pipes and 50% of urban drainage pipes will be used in urban drainage pipes. Water supply and hot water for buildings will be used by 2015. 85% of the supply and heating pipes are made of plastic tubes, 80% of urban water supply pipes (below DN400mm) are made of plastic pipes, 90% of rural water supply pipes are made of plastic tubes, and 40% of urban gas plastic pipes (medium and low-pressure lines) are used in construction wires. 90% of the threading and sheathing tubes are made of plastic tubes. According to forecasts, during the Twelfth Five-Year Plan period, my country's plastic pipe production will maintain a growth rate of about 10%. By 2015, the national plastic pipe production is expected to be close to 12 million tons, and the market share of plastic pipes in all types of tubes in the country will exceed 60%.

PPR Pipes Production Process

PPR is a random copolymer polypropylene synthesized by the gas phase method (PP and PE). Its structural feature is that the PE molecules are randomly linked among the PP molecules, and the molecular weight ranges from 300,000 to 800,000. The pipes produced from PPR raw materials are also called random copolymer polypropylene pipes. They are plastic pipe products developed and applied in the late 1980s and early 1990s. With its excellent performance and wide applications, it has occupied a place in the plastic pipe market and is a recognized green product. But in recent years, the market operation, the analysis mentioned above of PPR plastic pipe quality problems, and examples have found that there are many problems in the PPR pipe market, and these problems have restricted mainly the sound development of PPR pipes.

Advantages and disadvantages of various materials

PPR tube is cost-effective and environmentally friendly

As a new type of water pipe material, PPR pipe has unique advantages. It can be used as a cold water pipe or a hot water pipe. The interface of the PPR pipe adopts hot-melt technology, and the lines are completely fused. Therefore , once the installation and pressure test pass, it will not be aging and leaking after a long time like the aluminum-plastic pipe.
Advantages: moderate price, stable performance, heat insulation, corrosion resistance, a smooth inner wall without scaling, safe and reliable piping system, impermeable, and the service life can reach 50 years.
Disadvantages: high construction technology requirements, special tools, and professionals are required to ensure the system's safety.

Corrosion resistance and sterilization of copper pipe

It is a first-class product in water pipes. There are two ways to connect copper pipes: ferrule and welding. The ferrule is the same as aluminum-plastic pipe, and it has had the problem of aging and water leakage for a long time . Most copper pipes are installed by welding. Welding means that the joints are welded together by oxygen to be the same as PPR water pipes and never leak. Because of its high price, it is generally used in high-end apartments or villas.
Advantages: high strength, stable performance, sterilization, and not easy to corrode.
Disadvantages: high price and rugged construction. It is easy to cause heat loss, increased energy consumption, and increased use cost in the cold winter.

Aluminum plastic pipe is easy to age and leak.

Aluminum-plastic pipe was once a famous pipe on the market. Because of its lightweight, durability, and convenient construction, its flexibility is more suitable for home furnishing. In Guangdong and Shanghai, where the decoration concept is relatively new, the aluminum-plastic pipe has gradually disappeared from the market and is a product that has been eliminated.
Advantages: The price is relatively low. It can be bent arbitrarily, the smooth surface, and the conventional construction.
Disadvantages: accessible to age, many hidden dangers, and short service life. The practice has proved that after one year of use, the pipe joints are prone to leakage.

Galvanized pipe is easy to be blocked and easily polluted.

You suddenly open the water pipe you haven't used for a long time, and you find that it is "yellow" water flowing out. In the past, this kind of thing was straightforward in the galvanized iron pipe in the old house. Such "yellow" water is also harmful to the human body. Four ministries and commissions, including the Ministry of Construction of China, also issued documents clarifying that galvanized pipes have been banned since 2000. These are rarely used for cold water pipes in newly built communities .
Advantages: complete varieties and many matching fittings.
Disadvantages: it belongs to the obsolete products banned by the state. It is easy to corrode and rust, resulting in poor water flow and easily polluting the water source.

PVC pipe is easy to break and deform

It is a kind of plastic pipe, and the joints are usually glued together. Because of its poor frost resistance and heat resistance, it is difficult to use as a hot water pipe; the strength is not suitable for the pressure requirements of water pipes, so cold water pipes are rarely used. In most cases, PVC pipes are ideal for wire pipes and sewage pipes. In addition, the chemical additive phthalate, which makes PVC softer, has a significant impact on the kidneys, liver, and testicles in the human body and can cause cancer and kidney damage, so it is not recommended to buy.
Advantages: light, easy to install, low cost, and not perishable.
Disadvantages: poor quality will be brittle, easy to break, and easily deform when exposed to heat.

The correct way to distinguish the advantages and disadvantages of PPR water tubes.

A. The high quality PPR water color IS soft bright and oily feeling. The poor PPR water mixed with low-grade plastic or lime powder, the color look not natural, cut section dry and oil-free texture, so it feels like adding a chalk.

B. High quality PPR water pipe has smooth inside and outside walls. No concave and convex cracks. But the bad PPR pipe wall is rough and has concave and convex feeling.

C. The quality of PPR pipe' weight is heavier than inferior PPR water. Due to high quality PPR brass fitting having above three waterproof groove copper (copper content greater than fifty-eight percent), the size of long pieces of copper, the thickness is thicker, so weight PPR is heavier than inferior fittings.

D. High quality PPR material is a hydrocarbon chain compound .In flame temperature above 800 degrees with the ideal combustion condition and sufficient oxygen condition, burning only carbon dioxide and water vapor release. Combustion should be no odor and residue, but poor due to the poor quality of the plastic pipe with PPR and other impurities there will be odor and residue burning. Cut the thin slices from the PPR hose and identify them with a lighter burner.

Nowadays, ppr pipe fittings are becoming more and more popular in society, involving water supply, sewage, irrigation, gas transmission and other uses. Due to its own advantages and characteristics, it can stand out in the pipeline market and occupy a very important position.

Because of the robust nature of PPR, most plumbers and civil engineers like to use PPR for their works. It gives that expect finishing needed for your house. PVC pipes are known to fade out easily over time and start to release chemicals into the water.

The reason most homeowners do not generally like PPR is because of the price. The price of PPR is a bit higher than the usual PVC. But this seems to be the case everywhere. The PPR is expensive and worth every dim.

FAQ

What is PPR pipes in plumbing?

PPR pipe is a straight and rigid cylindrical pipe, made from Polypropylene Random Copolymer plastic, produced through a continuous extrusion process. They are commonly offered in green or white color, and in outer diameter sizes ranging from 20mm to 110mm making the pipe walls far thicker than PVC.

Is PPR pipe safe for drinking water?

PPR is the short-form for Polypropylene Random Copolymer while CPVC is Chlorinated Polyvinyl Chloride is produced by a process of chlorination to Polyvinyl Chloride. PPR is superior to CPVC not because of wide acceptability but also it is safe for potable water.

What is difference between PVC and PPR pipe?

Materials are different: PVC is made of polyvinyl chloride, and PPR is made of random copolymer polypropylene. Color difference: PPR pipe toughness is better than PVC, and good quality and bright color, others have a light milky yellow, and poor-quality color and chaos.

Why are PPR pipes used?

PPR pipe fittings are usually used in the construction of cold and hot water systems. The ability of PPR pipes to withstand both hot and cold temperatures without breaking or cracking makes it the best option for cold and hot water systems. ... PPR pipe fittings are also used as purified water supply systems.

How do you use a PPR pipe?

Press the PPR pieces straight into/onto their respective sockets.
Push the pipe into the female socket until you reach the depth marking you put on it.
Push the fitting onto the male socket until it touches the ridge or line marked on the socket.

How many types of PPR pipes are there?

The raw material of PPR is separated into 3 groups according to heat, pressure and durability for chemicals. These are Type-1(polypropylene homo polymer), Type-2(polypropylene block copolymer) and Type-3 (Polypropylene Random copolymer). Type-3 is more performers against physical and chemical than Type-1 and Type-2.

How to connect PPR water pipes?

PPR water pipe installation first needs to pay attention to the prohibition of smashing water pipes, especially in winter, because PPR water pipes are cold and fragile.
PPR water pipes are installed by heat welding method to connect pipes and fittings together. Before welding, clean the welding part of the water pipe and check whether there are cracks in the water pipe port.
The heat welding temperature of PPR water pipes is generally 260℃-270℃, below or above this temperature will lead to poor welding and potential water leakage. According to the PPR welding specification, the welding depth, heating time, operation time and cooling time of PPR water pipes vary according to the diameter of the pipe.
It is also important to note that after the installation of the water pipe, a pressure test is required and after the test, the installation of the water pipe is considered.

PPR pipe installation to pay attention to what points?

1, PPR pipe is first of all a relatively low hardness product, so when carrying or construction or careful protection to avoid damage to PPR water pipes caused by external forces.
2, connected pipes and fittings these are also to achieve a balanced state, do not tilt, so that you can avoid faucets installed at the wrong angle, resulting in no normal and correct installation.
3, PPR water pipes to know that it exists a certain low-temperature brittleness, if you are installing it in the winter to be particularly careful, especially when cutting PPR water pipes action to slow cut, there are installed water pipes can not be used to knock or heavy pressure, if necessary, to implement a protective cover on the parts vulnerable to external pressure.
4, PPR water pipes are prone to aging if they are exposed to ultraviolet light for a long time, so install PPR water pipes outdoors or in direct sunlight to add a layer of protection.
5, PPR water pipe installation must be pressurized, you can use a metal hose to connect the hot and cold water pipe outlet faucet, which can ensure that the hot and cold water pipes at the same time under pressure will not cause PPR water pipe leakage.

PPR water pipe joint leakage how to do?

1, first of all, you can use the method of glue, this method is more suitable for low-pressure pipes, this method used in PP-R products operating pressure is not more than 4 kg or not very suitable, because the PP-R material determines the glue is generally difficult to dissolve.
2, if you choose to continue to connect the thicker wall thickness of the pipe, then you can use hot melt adhesive directly outside the welding, the gap will be blocked, this method also can not have too high a pressure.
3, you can use a welding torch, first of all, the solder should be sprayed directly into the welding nozzle, this method can be used with PP-R patch welding rod to use.
4, other wrapping or steel-plastic clay, this feeling is not particularly sanitary, barely, you can try.
5, in fact, the most thorough method than, break off and reinstall, this method is actually not difficult, as long as you do not hide the pipe into the wall should be able to implement, and the most thorough, because the advantages PP-R pipe is originally welded strength than the local high, to ensure the overall sealing of the pipe.
6, if there is still a chance, then the construction must be carried out in accordance with the specifications, but also choose the brand of pipe industry is good, but also choose a better welder.

Key: PPR pipe in the installation of the time or pay special attention to the later problems, repair is also more difficult.
