HDPE water pipe is a pipe made of high-density polyethylene, which is widely used in water supply, drainage, irrigation and municipal construction. Due to its excellent physical and chemical properties, HDPE water pipe has become an indispensable infrastructure in modern water conservancy, construction and industrial projects. HDPE water pipe has many advantages such as corrosion resistance, anti-aging, long service life, easy installation, and meets environmental protection requirements. It is an ideal substitute for traditional steel pipes and PVC pipes.
The specifications and models of HDPE water pipes vary according to different factors such as outer diameter and wall thickness. Common specifications include:
Outer diameter (OD): 20mm to 1200mm
Wall thickness (SDR): SDR11, SDR13.6, SDR17, etc.
Length: usually 6 meters or 12 meters, which can be customized according to customer needs
Different specifications and models can be selected according to specific application requirements to meet the water pipe installation requirements in different environments.
HDPE water pipes are produced and tested in strict accordance with international standards to ensure the high quality and high performance of the products. All products undergo strict quality inspection before leaving the factory and comply with standards such as GB/T 13663 and ISO 4427 to ensure that the quality of each water pipe meets industry requirements.
1. Strong corrosion resistance
HDPE water pipes have excellent corrosion resistance and can resist the erosion of acids, alkalis, salts and various chemicals. Whether in acidic or alkaline environments, HDPE water pipes can maintain a long service life, avoiding the problem of easy rust and corrosion of steel and iron pipes.
2. Impact resistance
HDPE water pipes are made of high-density polyethylene material, which has high impact resistance and can effectively withstand external force collisions without being easily damaged. They are particularly suitable for use underground or in complex geological environments.
3. High and low temperature resistance
HDPE water pipes have a wide temperature adaptability range and can be used normally in an environment of -40℃ to +60℃. They are not easy to deform or break in high or low temperature environments.
4. Not easy to scale
Due to the smooth surface of HDPE water pipes, low water flow resistance, and not easy to accumulate sediment, it can effectively avoid scaling, keep the water flow smooth, and extend the service life of the pipe.
5. Long life
The service life of HDPE water pipes can usually reach 50 years or even longer, which is much more durable than water pipes made of traditional materials. Its wear-resistant and anti-aging properties ensure that there will be no problems such as leakage during long-term use.
6. Environmental protection and health
HDPE water pipes meet international environmental protection standards, do not contain any harmful substances, and the water quality is safe and hygienic. It is suitable for drinking water transportation and meets environmental protection and health requirements.
7. Easy installation
HDPE water pipes use hot melt connection technology, which is easy and quick to install. Hot melt connection can ensure the sealing and long-term stability of the pipe interface, and reduce the risk of leakage during installation compared to traditional threaded connection or adhesive connection.
1. Urban water supply system HDPE water pipes are widely used in urban drinking water delivery systems, including water supply pipes for tap water networks, residential areas, commercial buildings, etc. Its safety and durability make it an ideal pipe in urban water supply systems.
2. Agricultural irrigation In agricultural irrigation systems, HDPE water pipes have good wear resistance and UV resistance, and are suitable for various irrigation methods, such as drip irrigation, sprinkler irrigation and shower irrigation. Its good flexibility and low temperature resistance can adapt to different geographical environments and climatic conditions.
3. Drainage and sewage systems HDPE water pipes are also widely used in drainage systems, especially in sewage and wastewater pipes. It has strong corrosion resistance and UV resistance, and can maintain good use for a long time.
4. Industrial field HDPE water pipes can also be used in industrial pipeline systems such as chemical, petroleum, and mining, and are especially suitable for conveying corrosive substances, liquids and gases. Its high temperature resistance and corrosion resistance make it an important material for industrial pipelines.
5. Municipal Engineering HDPE water pipes are also widely used in municipal engineering projects, such as road water supply pipelines, park water supply networks, underground fire protection systems, etc., to adapt to different environments and engineering needs.
HDPE pipe (high-density polyethylene pipe) is a pipe material produced with high-density polyethylene as raw material. It is widely used in various fields, such as municipal engineering, agricultural irrigation, oil and gas transportation, chemical industry, and power, telecommunications and other facilities. It has become one of the indispensable materials in modern pipeline systems due to its excellent physical and chemical properties.
HDPE pipe is made of high-density polyethylene material and has many outstanding characteristics. It is especially suitable for pipeline systems that need to be used for a long time and withstand high pressure. Its main features include:
1. Strong corrosion resistance: HDPE pipe has good corrosion resistance to most acids, alkalis and organic solvents, and can be used for a long time in harsh environments.
2. Strong pressure resistance: Due to the structural characteristics of high-density polyethylene, HDPE pipe has strong pressure resistance, can withstand large internal and external pressures, and is suitable for various high-pressure occasions.
3. Anti-aging and weather resistance: HDPE pipe has excellent UV resistance, and even under sunlight exposure, it will not lose its function due to aging.
4. Low temperature resistance: HDPE pipe can maintain good performance in low temperature environments and is suitable for applications in cold areas.
5. High safety: HDPE pipes are non-toxic and meet environmental standards, and are particularly suitable for the transportation of drinking water and food-grade piping systems.
6. Strong flexibility: HDPE pipes have good flexibility and can be bent and adjusted according to actual needs, making installation easier.
1. Municipal engineering: HDPE pipes are widely used in urban water supply, drainage, sewage treatment, rainwater discharge and other pipeline systems. They can effectively reduce the leakage rate of water pipes and improve the stability of water supply systems.
2. Agricultural irrigation: The corrosion resistance and pressure resistance of HDPE pipes make it a commonly used material in agricultural irrigation systems. It can withstand high water pressure, reduce pipe rupture and leakage, and ensure the efficient operation of farmland irrigation systems.
3. Oil and gas transportation: HDPE pipes can be used for the transportation of oil and natural gas. Because of its strong corrosion resistance, it can resist the erosion of chemical media during transportation.
4. Electricity and telecommunications: In the field of electricity and telecommunications, HDPE pipes are often used as protective pipes for cables. Its wear resistance and resistance to external pressure can effectively protect cables from damage from the external environment.
5. Chemical industry: HDPE pipes are often used for the transportation of chemical substances, especially in situations where strong acid and alkali corrosion resistance is required, which can ensure the safe operation of pipelines.
1. Easy installation: HDPE pipes have flexible connection methods. Common connection methods include hot melt connection, electric fusion connection and mechanical connection. You can choose the appropriate method according to different construction requirements. Hot melt connection has good sealing and is not easy to leak.
2. Durability: HDPE pipes have a long service life, generally more than 50 years, and basically do not require much maintenance after installation.
3. Easy maintenance: Once the HDPE pipe is damaged, it can be repaired by hot melt or electric fusion welding, with low maintenance cost and high efficiency.
