PPR pipes are one of the main materials used in modern home decoration and construction due to their unique advantages and characteristics, which have gained favor among many consumers and manufacturers, leading to their widespread application in various areas. However, when purchasing PPR pipes, many people may not know how to choose them due to a lack of understanding. Therefore, I will introduce the specifications and price of PPR pipes. **Dengquan Plastics:** [http://www.zgdqsy.com/](http://www.zgdqsy.com/) **Hotline:** 17773665301 **Introduction to PPR Pipe Specifications and Prices Part One** Since its development, PPR pipes have undergone multiple technological reforms and have become the main material in the construction water pipe industry due to their unique advantages. So, what are the advantages of PPR pipes? Compared to other types of pipes, PPR pipes offer a high cost-performance ratio, are very environmentally friendly and non-toxic, and will not harbor dirt inside the pipes even after long-term use, ensuring that the quality of the water flow is relatively safe. They are resistant to high temperatures and corrosion, have an extremely long service life, and are manufactured according to national standards, so there are no safety concerns. Additionally, PPR pipes are very affordable and reasonably priced. **Introduction to PPR Pipe Specifications and Prices Part Two** PPR pipes, commonly known as three-type polypropylene, are a type of water pipe commonly used in home decoration. Compared to traditional pipes, PPR pipes have advantages such as energy efficiency, corrosion resistance, environmental friendliness, easy installation, smooth inner walls that do not accumulate scale, and a long service life. Therefore, they are widely used in construction sites, sewage pipelines, urban gas pipelines, and liquid transportation. With the continuous development of water pipes in recent years, the current stage of PPR pipes is not easy to achieve. The price of PPR pipes in the market is generally determined by their specifications. **Introduction to PPR Pipe Specifications and Prices Part Three** Regarding the price of PPR pipes, one must first mention their specifications. Only by clearly understanding the specifications of PPR pipes can one choose a suitable price based on the size. According to national standards, the main diameters of PPR pipes available in the market are 32, 20, 50, 75, 63, 25, 40, 110, and 160 mm. For home decoration, sizes around 20, 32, and 25 mm will suffice. The price of PPR pipes varies according to these specifications, calculated per meter. For example, if the diameter of the PPR pipe is 20 mm, it would cost around 24 yuan per meter. **Introduction to PPR Pipe Specifications and Prices Part Four** PPR pipes are also divided into hot water pipes and cold water pipes. If you purchase a blue PPR pipe, it indicates that it is a cold water pipe, whereas a red PPR pipe signifies a hot water pipe. In addition to these two colors, there are other colors as well. The reason for the variety of colors in PPR pipes is that manufacturers use different colored granules during production and add different masterbatches, resulting in colors such as white, gray, green, red, and blue. The color of the PPR pipe does not affect its price; it is still calculated based on the specifications according to the cross-sectional area.

The new type of PPR pipe currently used in construction is the advanced hot and cold water pipe in the country, and major design institutes across the country are promoting the use of aluminum-plastic composite pipes. **PP Board Product Features Little Secrets Revealed** PPR pipes are generally divided into three colors: green, white, and gray, with common specifications ranging from D16 to D110, including D16, D20, D25, D32, D40, D50, D63, D75, D90, and D110. External diameters (in millimeters) include 20, 25, 32, 40, 50, 63, 75, 90, 110, and 160. Additionally, there are other specifications referred to, such as 4 points, 6 points, 1 inch, 1.25 inches, 1.5 inches, 2 inches, 2.5 inches, 3 inches, and 4 inches. **Water Pipe Specification Dimensions** Common water pipe specifications include: DN15 (4-point pipe), DN20 (6-point pipe), DN25 (1-inch pipe), DN32 (1.25-inch pipe), DN40 (1.5-inch pipe), DN50 (2-inch pipe), DN65 (2.5-inch pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), DN250 (10-inch pipe), etc. **Convenience of PP Pipe Application in Daily Pipelines** **PPR Pipe Connection Methods** There are many connection methods for PPR pipes on the market, but different types have different connection types. The commonly used method is the hot melt connection method, where pipes and fittings are connected in one go. Similar materials can easily connect with each other, making this method relatively reliable. The connection between the pipes is tight, with strong sealing and durability. When connecting PP pipes, one should first remove dust and foreign objects from the pipe, insert the pipe end into the heating sleeve without rotating, until the predetermined depth is reached. Similarly, connect the fittings to the heating head without rotating, heat them, and when they reach a certain temperature, immediately remove the pipe and fitting from the heating sleeve and heating head, then quickly rotate them, applying even force to reach the same depth. After connecting, the pipe should be kept cool for a sufficient time before releasing. As a new type of pipe material, PP-R pipes possess the following performance characteristics: 1. **Energy-saving** - The production energy consumption of PP-R pipes is only 20% of that of steel pipes, and their thermal conductivity is low [0.2W/(M.K)], only 1/200 of that of steel pipes, significantly reducing heat loss when applied in hot water systems. 2. **Corrosion-resistant, scale-free, hygienic, and non-toxic** - Using PP-R pipes eliminates the "secondary pollution" of water quality caused by scaling and rusting of galvanized steel pipes. Due to the pure composition of PP-R, which mainly consists of carbon and hydrogen, it meets food hygiene regulations, is non-toxic, and is more suitable for drinking water transportation. 3. **Heat-resistant, pressure-resistant, and long service life** - PP-R pipes can withstand long-term usage temperatures of up to 95℃, and short-term usage temperatures can reach 120℃. Under the condition of 70℃ working temperature and 1.2MPa working pressure, they can last over 50 years of continuous use. 4. **Lightweight, high strength, and low fluid resistance** - The density of PP-R pipes is only 1/8 of that of metal pipes, with a pressure test strength of up to 5MPa, good toughness, and impact resistance. With smooth inner walls that do not rust or scale, they have low fluid resistance. 5. **Non-toxic and hygienic** - The raw material molecules of PP-R consist only of carbon and hydrogen, with no harmful toxic elements, making them reliable and hygienic, suitable not only for hot and cold water pipelines but also for pure drinking water systems. 6. **Insulation and energy-saving** - PP-R pipes have a thermal conductivity of 0.21W/mk, which is only 1/200 of that of steel pipes. 7. **Good heat resistance** - The Vicat softening point of PP-R pipes is 131.5℃. The working temperature can reach 95℃, meeting the requirements of hot water systems in building water supply and drainage specifications. 8. **Long service life** - Under a working temperature of 70℃ and working pressure (P.N) of 1.0MPa, the service life of PP-R pipes can reach over 50 years; at room temperature (20℃), the service life can reach over 100 years. 9. **Easy installation and strong connections** - PP-R has excellent welding performance, and pipes and fittings can be connected using hot melt and electric fusion methods, making installation easy and connections strong, with the strength of the joint being greater than that of the pipe itself. 10. **Recyclable materials** - PP-R waste can be cleaned and crushed for recycling into pipes and fittings. The amount of recycled material does not exceed 10% of the total, ensuring that product quality is not affected. **Main Applications** 1. Hot and cold water systems in buildings, including centralized heating systems; 2. Heating systems inside buildings, including floor, wall, and radiant heating systems; 3. Pure drinking water supply systems that can be consumed directly; 4. Centralized air conditioning systems; 5. Industrial pipeline systems for transporting or discharging chemical media, etc.
