HDPE pipe (high-density polyethylene pipe) is a plastic pipe made of high-density polyethylene and formed by extrusion. Due to its excellent corrosion resistance, aging resistance, toughness and strong pressure resistance, it is widely used in municipal, industrial, agricultural, construction and other fields. As an environmentally friendly and efficient pipeline system, HDPE pipe has gradually replaced traditional steel pipes and cement pipes and occupied an important position in the market.
300mm HDPE pipe specifications
300mm HDPE pipe refers to a high-density polyethylene pipe with a diameter of 300 mm. Compared with other sizes of HDPE pipes, 300mm pipes are suitable for large-flow transportation occasions, and are commonly found in municipal water supply, drainage systems and large-scale sewage projects. The specifications of 300mm HDPE pipes usually include the following important parameters:
1. Pipe outer diameter: 300mm, indicating the outer diameter of the pipe.
2. Pipe inner diameter: The inner diameter varies depending on the wall thickness. Generally, the thicker the wall, the smaller the inner diameter of the pipe.
3. Pipe wall thickness: The wall thickness of a 300mm pipe is usually between 8mm and 20mm. The specific wall thickness is selected according to different usage requirements and pressure levels.
4. Pipe pressure level: Common pressure levels for HDPE pipes include PN6, PN8, PN10, PN12.5, PN16, etc., which indicate the maximum working pressure that the pipe can withstand during use. PN6 indicates a working pressure of 6 bar (0.6MPa), PN10 indicates a working pressure of 10 bar (1.0MPa), and so on.
5. Pipe length: Usually 6 meters/section or 12 meters/section, but it can also be customized according to needs.
300mm HDPE pipe price
The price of HDPE pipe is affected by many factors, such as raw material price, production process, pressure level of pipe, wall thickness, brand of manufacturer and purchase quantity. According to the general situation in the current market, the price of 300mm HDPE pipe is roughly between 200 yuan and 500 yuan per meter.
The specific price range is as follows:
Ordinary type (low pressure level, thin wall thickness): price is about 200 yuan-300 yuan per meter.
Medium type (medium pressure level, standard wall thickness): price is about 300 yuan-400 yuan per meter.
High strength type (high pressure level, thick wall thickness): price is about 400 yuan-500 yuan per meter.
In addition, the transportation, installation and other additional services of the pipe will also affect the final price. If it is purchased in large quantities, there will usually be a certain discount.
Application
Due to its excellent performance, 300mm HDPE pipe is widely used in the following fields:
Municipal water supply system
300mm HDPE Water Supply Pipe is widely used in municipal water supply projects, especially in areas with large water supply. Because HDPE pipes have good corrosion resistance, they can effectively avoid the problem of traditional iron pipes and cast iron pipes affecting water quality due to rust during long-term use. In addition, HDPE pipes also have high toughness and crack resistance, and the pipes are not easy to break even in the case of ground subsidence or movement.
Urban drainage system
300mm HDPE Drainage Pipe plays an important role in urban drainage systems. They are used to transport rainwater and sewage, especially as a main component of sewage treatment plants and sewage pipe networks. The chemical corrosion resistance of HDPE pipes enables them to resist the erosion of various corrosive substances in sewage and maintain a long service life.
Agricultural irrigation
In agricultural irrigation systems, 300mm HDPE pipes are used as water delivery pipes, which can effectively transport water to various irrigation points. Because HDPE pipes have good pressure resistance and fluid transmission efficiency, they can improve the efficiency of irrigation systems, save water resources and reduce water leakage.
Oil and gas transportation
HDPE pipes are also widely used in the transportation of oil and gas. Due to its high pressure resistance and corrosion resistance, HDPE pipes can effectively avoid leakage during transportation and improve the safety of the pipeline system.
Industrial use
300mm HDPE pipes can also be used in industrial fields, such as transportation pipelines in chemical production. HDPE pipes have strong tolerance to a variety of chemicals, so they are widely used in chemical, pharmaceutical and other industries, which can effectively avoid chemical leakage and pollution.
Thermal pipelines
300mm HDPE pipes can also be used in thermal transmission systems, especially in urban heating systems. Through special insulation design, HDPE pipes can effectively reduce heat loss and ensure the efficient operation of the heating system.
300mm HDPE pipe plays an important role in the construction of various infrastructures with its excellent physical properties and adaptability. With the society’s attention to environmental protection and engineering cost control, the application of HDPE pipes in water conservancy, sewage, oil and gas and other fields will become more and more extensive. In terms of price, the price of 300mm HDPE pipe will vary according to specific needs and purchase volume, but compared with traditional pipe materials, HDPE pipes have obvious advantages in economy and durability. In the future, with the advancement of production technology and the continuous growth of market demand, the types and specifications of HDPE pipes will be more abundant, and the market prospects will be broad.
