HDPE pipe for water supply

JUNNUO HDPE pipe is a perfect solution for municipal engineering system and urban water supply and drainage system. HDPE pipe adopts high-quality original  PE100 raw material, with the size range of DN 16-1600mm, and the performance conforms to ISO4427 standard and other national certification standards. HDPE pipes for water supply can be manufactured with different rated pressures, mainly: sdr11-pn16 bar, sdr13.6-pn12.5 bar, sdr17-pn10 bar, sdr21-pn6 bar, sdr26-pn6 bar, etc

HDPE pipe for water supply is a pipe made of high-density polyethylene (HDPE) material, which is specially used for conveying liquids and gases. HDPE pipe is widely used in municipal engineering, agricultural irrigation, petrochemical, mining engineering, water supply and drainage engineering and other fields due to its excellent physical properties and chemical stability. The main component of this pipe is polyethylene, which is made of high-density material. It is an upgraded product of traditional steel pipes, can withstand a certain pressure, and has good mechanical properties.

Application

HDPE pipe for water supply is mainly used in municipal engineering water supply systems, indoor water supply systems of buildings, outdoor buried water supply systems, residential areas, buried water supply systems in factory areas, as well as old pipeline repairs, water treatment engineering pipeline systems, gardens, irrigation and other fields of industrial water pipes. ‌

The reason why HDPE water supply pipe is widely used is mainly due to its unique properties and advantages. First of all, the main component of HDPE pipe is high-density polyethylene, which has excellent corrosion resistance and can resist various acid and alkali corrosion, so it is very suitable for conveying acidic and alkaline substances, such as sewage, natural gas, coal gas, etc. Secondly, HDPE pipes have good environmental adaptability and frost resistance, and can be used for both indoor and outdoor water supply pipes. In addition, it is light in weight, easy to install and handle, and has strong wear resistance and good hydraulic properties. It does not require outer protection when used underground, and is particularly suitable for earthquake areas and mining areas where soil layers have settled. HDPE pipes also have a service life of more than 50 years, good environmental adaptability and frost resistance, making them an ideal choice for water supply systems.

The application of HDPE pipe for water supply not only improves the safety and reliability of the water supply system and reduces the leakage rate of urban pipe networks, but also reduces labor costs and installation costs due to its light weight and easy installation. At the same time, its non-toxic, non-corrosive, and non-scaling properties effectively improve the water quality of the pipe network, while its low inner wall roughness can effectively reduce water supply energy consumption. These characteristics make HDPE water supply pipes occupy an important position in the water supply industry and are widely used in various fields to ensure the safety and efficient use of water.

Connection method

‌Butt-melt connection‌: This is a common connection method suitable for pipes with larger diameters. By using a dedicated HDPE Pipe Welding Machine, the two ends of the pipe are heated to a molten state, and then quickly butted together to fuse the two ends into one, thereby ensuring the firmness and sealing of the connection.

‌Electric heat fusion‌: Electrofusion connection‌ is a connection method achieved through HDPE Electrofusion Fittings, which is suitable for places where hot melt connection cannot be implemented due to the constraints of the installation location. In this connection method, the same thermoplastic pipe will be inserted into a special electrofusion fitting when connecting. The electrofusion fitting is energized by the electrofusion connection machine, and the required heat is generated by the resistance wire pre-buried inside the electrofusion fitting for welding.

‌Flange connection‌: When the HDPE pipe needs to be connected to other pipes or equipment, a flange connection can be used. The flange connection tightly connects the two flange ends together through bolts and gaskets, which is suitable for occasions where a more flexible connection is required.‌‌

HDPE pipe is the perfect solution for municipal water supply and drainage system, urban water supply and drainage. HDPE pipes are increasingly popular worldwide for water supply and drainage because of its advantages:

• Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.
• No leakage: The polyethylene pipe system is connected by electrofusion and butt fusion methods, and the strength of the joint is higher than the strength of the pipes.
• High toughness: The elongation at break of HDPE pipes is generally above 500%. For the uneven settlement of the foundation engineering construction, its adaptability is very strong and the seismic performance is good.
• Excellent resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress crack resistance is also outstanding.
• Excellent flexibility: Excellent flexibility and scratch resistance.
• Rapid Crack Propagation: Rapid Crack Propagation (RCP) for polyethylene plastic piping systems.
• Low temperature impact resistance: Low temperature impact resistance: Polyethylene has a very low temperature embrittlement temperature and can be safely used in the temperature range of -60-60 °C. In winter construction, due to the good impact resistance of the material, the tube will not be brittle.
• Good wear resistance: Good wear resistance, low wall friction coefficient, low flow resistance and strong conveying capacity.
• A variety of new construction methods: HDPE pipelines have a variety of construction techniques, in addition to the traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, liners Construction in the form of split pipes, etc. which is a good choice for some places that are not allowed to be excavated.
• Low system cost: Low system cost and low maintenance cost can greatly reduce project costs.
• Long service life: The buried HDPE pipe is normally used for 70 years.
• Recyclable, environmentally friendly: HDPE materials can be reused, fully in line with the nationally advocated efficient environmental protection concept.
• Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install. The lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
