“Advantages and Disadvantages of Plastic Pipe Fitting Materials
Plastic pipes fitting materials is high-tech recombination type chemical construction material, and chemical construction material is the fourth new-type building material following with steel material, wood material and cement. Because of plastic pipe fitting materials has small flow loss, energy-saving, material-saving, ecology protection and easy to construct, it is widely used in building water supply and drainage, cities water supply and drainage and gas pipes fitting area, becoming a main force in urban construction.
Advantages of plastic pipes fitting materials
1.Hydraulic characteristic. The plastic pipes fitting material has advantages of smooth pipe wall, low resistance, large water flow amount. When come across gradient terrain, we can reduce plastic pipe fitting’s aperture in smaller construction capacity.
2.Sealing. Cement pipe has worse sealing property, and concrete pipe belongs to rigid pipe, slightly move may damage the connecting part. What’s more, cement pipe is sealed by vulcanized rubber ring, plastic pipes fitting is sealed by TPE sealing ring. Plastic pipes fitting’s service life is longer than cement pipes.
3.Service life and corrosion resistance. Cement pipe’s service life only has 15 years while plastic pipes fitting has a quite long service life of 50-100 years, and plastic pipes fitting has better corrosion resistance than cement pipes.
4.Laying and construction. Plastic pipes fitting has properties of light weight, longer, fewer pipe joints, easy to connect and construct and lower construction cost.
Disadvantages of plastic pipe fitting materials
1.Worse tensile strength and tenacity. Fine UPVC pipe’s has larger ductility, while worse plastic pipe fitting materials always has brittleness and low ductility, that is easy to breakage.
2.Worse shock resistance. Testing falling weight impact according to GB/T5836.1－92 standard, we found that the first time pass rate of plastic pipe fitting materials is lower than 50%.
3.Lower softening temperature and easy to thermal deformation. In order to enhance softening temperature, some manufacturers just simply increase the feeding amount, this does have beneficial for increasing softening temperature, but it greatly reduce the impact resistance, tensile strength and tenacity of plastic pipe fitting materials at the same time.
Advantages Of PPR Pipe
PPR pipe is a new type of energy-saving pipeline product, which mainly has the following characteristics:
1.Lightweight: density is 0.91g/cm3, ppr tube is only one-ninth of steel pipe, and one-tenth of copper pipe. Due to its lightweight, it can greatly reduce the transportation cost and the construction intensity of installation.
2.Hygienic and non-toxic green building materials: PPR pipes are polyolefin thermoplastics, whose molecules are only composed of carbon and hydrogen, without harmful and toxic elements, and have reliable hygienic performance. The whole process of raw material synthesis, molding processing, product use, and disposal will not cause adverse effects on the human body and the environment and is called green building materials. PPR pipes can be used not only in cold and hot water systems but also indirect drinking water systems.
3.Heat-resistance and heat preservation are energy-saving products: PPR pipe Vicat heat-resistant temperature is 131.3℃. Under certain working pressure and 70℃ working temperature, it can be used for a long time (more than 50 years), and the maximum working temperature is 95℃. Fully meet the requirements of the hot water system specified in the building water supply and drainage design code.
4.Good heat preservation performance: The thermal conductivity of the PPR pipe is 0.23w/m℃, which is only one-twentieth of that of steel pipe (43-52w/m℃). It has better heat preservation performance. Compared with metal pipes, Used in hot water and heating systems, it can save a lot of insulation materials and energy.
5.Hot-melt connection, safe and reliable: PPR pipe has good heat-welding performance. The hot-melt connection between pipes and PPR pipe fittings made of the same PPR material is the fusion of molecules and molecules, and there is no obvious interface. The entire pipeline system The connection becomes a whole, so the hot-melt connection of this method is more reliable than other pipes’ solvent bonding, mechanical connection, an elastic sealing socket connection, and the operation is simple, the speed is fast, and it is especially suitable for direct buried and hidden applications. During construction, there is no need to consider whether there will be leakage at the connection part during long-term use.
6.Good corrosion resistance: Except for a few oxidants, it can withstand the erosion of a variety of chemical media, will not rust, will not corrode, will not breed bacteria, and will not have electrochemical corrosion.
7.Water flow resistance is small: the inner wall of the ppr pipe is smooth, will not scale, and the wear resistance system is only 0.007, which is much lower than that of the metal pipe, and the water flow capacity is 30% higher than that of the metal pipe of the same specification.
8.The ppr tube has no pollution to the environment during production, construction, and use, and will not cause white pollution problems, and is a green product.
PE Pipe Material Advantages
How do you take all the best traits of a steel pipe and make it lighter and more flexible, while also introducing resistance to corrosion, weathering, and cracking? The answer is polyethylene (PE), a type of plastic that is rugged, flexible, and durable. And with a 100-year service life, PE pipes are among the longest lasting, most durable on the market.
Perhaps the most significant benefit of switching to PE pipes is its cost-effectiveness. PE pipes are cheaper to manufacture, transport, and install, all without compromising the design requirements of a project. The material’s advantages have cemented the role of PE pipes in modern construction, a role that won’t be displaced anytime soon.
Polyethylene: durability across the board
Products made of high-grade polyethylene can easily remain in service for 100 years, making it one of the most durable human-made materials on the planet. While its durability alone is laudable, PE also delivers a range of unique properties that extend its endurance. For example, these pipes are highly resistant to electrochemical-based corrosion, making it an outstanding material to transport corrosive materials or to withstand harsh environmental conditions.
Another PE property that works to enhance pipe durability is its flexibility and ductility—granting pipes outstanding resistance to fatigue. This is in stark contrast to other plastic pipes that are designed to withstand static pressures but do not perform as well under dynamic conditions and the surge events associated with normal system operation.
Finally, PE pipes are extremely smooth and highly resistant to fouling or biological buildup that could jeopardize flow characteristics within the pipe over the service life of the system
Adaptability promotes cost effectiveness without ignoring the environment
For large-scale projects requiring many interconnecting segments, PE pipes offer multiple options. These pipes can be joined together using heat fusion or various mechanical means thus assuring the system designer of connectivity and compatibility with existing system appurtenances. Fusion joints are especially beneficial, because pipes are brought together using heat to form a permanent, monolithic, and leak-free system. These leak-free systems are a significant benefit. For example, the American Society of Civil Engineers estimates that we lose about 6 billion gallons of drinking water per day in the United States, much through deteriorating joints in older pipe systems.
The flexibility of PE pipes also enables its installation via HDD. HDD allows you to strategically bore pipes under or around otherwise impassable areas like rivers or various structures. The HDD technology installs a durable, high performance PE pipe system while avoiding extensive excavation that can prove highly disruptive or extremely expensive.
PE pipes lead the way
The history of PE piping has been marked by an evolution in the technical performance of the stress-rated resins used to make these pipes. Even today, new polyethylene resin types are being introduced and applied in interesting ways. These innovative materials are the most recent technical development in polyethylene pipe grades and offer the end user exceptional resistance to slow crack growth and/or fatigue over the service life of the piping system. Under lab conditions, PE 100-RC versions outperformed standard PE 100 electro-socket fittings across the board—with up to 10 times the service life.
What are the Main Uses of PPR Pipe?
PPR Pipe has been growing in popularity over the last couple of years, and rightly so. Its durability, ecological, and economic benefits make PPR pipes one of the best in the industry. That is why most industry leaders have turned to PPR pipes for all their needs.
PPR pipes are commonly used in home installations. It is also used in sanitary liquid, alkaline and acidic solutions, compressed air, and transferring water. But what exactly is PPR pipe, and how is it used? We have prepared this comprehensive guide to help you learn everything about PPR pipes.
What is the PPR Pipe?
First things first, so what exactly is the PPR pipe? Also known as Polypropylene Random Copolymer, PPR pipe is a cylindrical and rigid pipe made from PPR. The pipe is produced through a continuous process known as extrusion. These pipes are usually white or green.
Most PPR pipes have a diameter of 20mm to 110mm. This means that the PPR pipe is thicker than its PVC companions. In addition to that, PPR pipes feature a network of fittings, accessories, and parts. These accessories are available for each PPR pipe diameter.
Like all other pipes, PPR pipes also have their unique properties. These properties set it apart from other pipes. Learn more about PPR pipes characteristics below:
Low Thermal Conductivity
The first thing you should about PPR pipes is that they have low thermal conductivity. This means that external temperatures don’t get to the liquid inside the pipe. Likewise, temperature from the liquid does not escape to the external environment. This is why PPR pipes minimize heat loss or heat gain during the transfer of cold and hot fluids. Using PPR pipes guarantees efficiency and reduced costs.
PPR pipes can serve you for more than 50 years under varying environmental conditions and a wide range of fluids. What is more, PPR pipes can withstand both cold and hot water systems. To help you understand, PPR pipes can handle the pressure and strain of hot water without breaking. Of course, the premise is that the 50-year life span can only be guaranteed under normal use conditions, such as protecting the pipeline under extreme weather.
Ecological and Economic Efficiency
PPR pipes are easy to transport, cut, and join. These pipes are also easy to use and do not need additional chemicals and materials.
What are the Main Uses of PPR Pipe Fittings?
As you have seen earlier, PPR pipes have several economic, ecological, and durability benefits. This is why these pipes are used in a variety of applications. Keep reading to discover the primary uses of PPR pipe fittings below:
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. Besides, its low thermal conductivity means that the fluids will retain the required temperature.
PPR fittings are the go-to option for discharging chemical fluids, including industrial waste. PPR piping is the ideal pipe fitting for industries due to its ability to withstand strong chemicals and alkaline solutions.
PPR pipe fittings are also used as purified water supply systems. These pipes are durable and can last for more than 50 years. What is more, they do not break or crack easily even under intense conditions.
The PPR pipes are perfect for a building’s heating system. These pipes can be installed inside floors, radiant, wall heating systems. These pipes can withstand all surfaces and conditions, making them the perfect option for all your heating needs.
What is a Composite pipe ?
Composite pipe, otherwise called compipe is a reinforced PVC pipe used for several purposes. They marry the benefits of both metal and PVC pipes to eliminate the shortcomings of either of them. Aluminum which is frequently used as the inner lining is efficient and reliable to eliminate gas diffusion into and from the pipe. It also helps in bringing down the snap back reflex and thermal expansion due to varying temperatures the pipe may be subject to. The aluminum in the middle is coated with PVC in both inner and outer layers. The layers are glued very expertly with special and strong adhesives so that they are coherent and reinforced pipe. The thickness of aluminum layer and the polyethylene layers are variable and are fixed according to the need of usage.
There are many advantages in the composite pipes as opposed to ordinary metal or PVC pipes that we are familiar with. The first and foremost advantage is corrosion resistance. The pipes are not easily corrodible by acids or chemicals. They also prevent or minimize the presence of scales that is the bane of ordinary pipes. So this insures a free and smooth flow of liquids or gases through these pipes. They can safely be used for hot or cold plumbing, drinking water systems, for centralized heating, for gas and chemical piping over long distances etc.
Longevity is another great advantage of these pipes. Pipes often crack and leak and have to be constantly replaced patched up etc. but not so with composite pipes. They are great money savers as they are functional even up to fifty years. They hold the shape that they are put into. This malleable nature is also a notable advantage of composite pipes. No additional structures or fixtures are needed to hold it and because of its smooth inner layer, these pipes have a better flow compared to ordinary pipes of the same diameter. This can prove invaluable when pipes are used for long distance transportation.They have a great burn resistance and can withstand high temperatures and graded accordingly.
