PP-R pipe, made from polypropylene random copolymer since 1990s, applying in cold and hot water supplyin buildings, with variety of advantages ad following :
- Light Weight : The density of the pipe is only 0.895-0.915g/m3, which is only 1/9 of steel pipe and 1/10 of copper pipe. It makes handling and installation more convenient.
- Good heat and pressure resistance : Its short-term operating temperature can up to 95°C. And under the temperature of 80°C, it still can bear some pressure for a long term. That’s the best choice for cold and hot water supply pipeline in buildings.
- Long Service Life : Under proper temperature and pressure, its service life can reach over 50 years.
- Good corrosion resistance : PP-R pipes have excellent corrosion resistance to most inorganic icon and common chemical substances in buildings. It is anti-corrosion and does not rust in long term use.
- Reliable and convenient connection : PP-R material has excellent melting welding performance. The pipes and fittings are made from the same material, joined together by melting welding. Compared to single pipe, the tensile, bending and impact strength in joint are much higher, which prevent the danger of leakage, and this kind of connection method aldo makes the site installation reliable and convenient.
- Nonpoisonous and harmless : PP-R belongs to polyolefin, which is a kind thermoplastics, whose molecule is only composed of carbon and hydrogen. And the sanitary property of materials for Sholin PP-R pipe and fittings has been certificated by national authority organization.
- Good thermal and sound insulation property : The thermal conductivity coefficient of PP-R if o.23w/m°C, which is only 1/200 of steel pipe (43-52w/m°C). No need to use insulating materials when used in hot water systems, which saves insulation materials and energy. And it has lower noise when water delivery in pipeline system.
- Better water passing capacity : The smooth inner surface of PP-R pipes and fittings have lower friction, which ensure fast running of the water.
- Environment- friendly building material : During production, installation and application, no pollution will be caused to the environment. Meanwhile, the materials are recyclable, which can minimize resource wasting.
PP-R pipes are commonly used for water pipes in homes and commercial buildings. They can be used for hot water, cold water, and pure drinking water.
Specifications
- Outer diameter: The outer diameter of PP-R pipes can be 20 mm, 25 mm, or 32 mm.
- Wall thickness: The wall thickness of PP-R pipes is specified by the nominal wall thickness (𝐸𝑁) in millimeters.
- Standard size rate (SDR): The SDR is the ratio of the nominal outer diameter (DN) to the nominal wall thickness (𝐸𝑁).
- Tube series: The tube series (𝑆) is a dimensionless number that represents the specifications of the PP-R pipe.
- Hydrostatic pressure rating: The hydrostatic pressure rating of PP-R pipes depends on the dimension ratio (DR) and wall thickness.
- Maximum working temperature: PP-R pipes can withstand temperatures of up to 95°C.
Properties
- PP-R pipes are non-toxic, hygienic, and can be recycled.
- PP-R pipes are heat resistant and can save energy.
- PP-R pipes are resistant to corrosion from acidic and basic solutions.
- PP-R pipes have a long service life.
- PP-R pipes are easy to install and connect.
PP-R pipes, or Polypropylene Random Copolymer pipes, have many characteristics, including:
- Durability: PP-R pipes are known for their longevity, with a lifespan of around 50–70 years.
- Lightweight: PP-R pipes are lighter than metal pipes.
- Flexibility: PP-R pipes are flexible enough to be easily joined and lifted.
- Easy installation: PP-R pipes are easy to install and can be joined with simple welding.
- Sustainability: PP-R pipes are recyclable and don’t release harmful chemicals when heated or burned.
- Chemical resistance: PP-R pipes are resistant to chemicals and bacteria.
- Hygienic: PP-R pipes are hygienic.
- Environmentally friendly: PP-R pipes are environmentally friendly and don’t harm the environment.
- Cost-effective: PP-R pipes are cost-effective.
PP-R pipes are a popular choice for plumbing and water supply applications in both residential and commercial settings.
FEATURES OF PPR PIPES
- Low Thermal Conductivity : PPR pipes have low thermal conductivity as the external temperatures don’t reach the liquid inside the pipe.
- High-temperature resistance : PPR pipes can withstand high temperatures up to 95°C, making them suitable for use in hot water supply systems.
- Long Lastin : PPR pipes have a long lifespan of up to 50 years or more under varying and extreme environmental conditions, making them a cost-effective option in the long term.
- Environment 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.
- Corrosion-resistant : PPR pipes resist corrosion from acidic or alkaline substances, making them a good choice for water supply systems.
- Easy to install : PPR pipes are lightweight and thus easy to install, which may help reduce our installation time and costs.
APPLICATIONS OF PPR PIPES
- Hot and Cold Water Supply Systems : PPR pipes are widely and equally used for hot and cold water supply systems in residential, commercial, and industrial buildings. They can withstand high temperatures and pressure and can distribute heat evenly which makes them ideal for transporting water in such systems. They are also used in heating systems such as under-floor heating etc.
- Chemical and Fluid Transport : As we know that PPR pipes are resistant to corrosion which makes them most suitable for transporting chemicals and fluids in industrial processes.
- Agricultural Irrigation Application : PPR pipes are extensively used for irrigation systems in the agriculture sector due to their durability and resistance to chemicals.
- Infrastructure : PPR pipes are also used in infrastructure projects like sewage systems, drainage systems, and cable conduits. These pipes’ resistance to corrosion and abrasion makes them ideal for such applications.
- Transporting Fluids and Chemicals : PPR pipes are used in transporting fluids and chemicals in industrial processes.Summarily, it can be concluded that these pipes are a versatile and durable option for a wide range of piping applications.
- Portable water pipe network for cold and hot water supply in civil buildings, such as residence, hospitals, hotels, offices, schools and buildings on ship, etc.
- Industrial pipe networks for foodstuff, chemical and electric industry. e.g. for the transportation of some corrosive fluids (acid or alkaline water and ionized water, etc).
- Pipe networks for purified water and mineral water.
- Pipe networks for air conditioning equipment.
- Pipe networks for floor heating system.
- Pipe networks for rainwater utilization system.
- Pipe networks for swimming pool facilities.
- Pipe networks for agriculture and horticulture.
- Pipe networks for solar energy facilities.
- Pipe networks for child water.
