Black drainage pipe is mainly PE pipe, which is made of special polyethylene as raw material and is extruded and molded by a plastic extruder at one time. This pipe has good weldability, resistance to environmental strain, and resistance to rapid stress cracking. It can be used safely for more than 50 years at rated temperature and pressure.
Raw materials and difference from water supply pipe materials
Black drainage pipe is usually made of PE recycled materials.
The main difference between HDPE Black drainage pipe and HDPE Water Supply Pipe is the raw materials used. PE water supply pipe must use 100% new high-density polyethylene raw materials. This is because the PE water supply pipe is used to transport drinking water, and it must be ensured that the produced pipe has a health license, which is the most basic requirement.
PE drainage pipe is used to transport sewage, so recycled materials can be mixed in the materials under the condition of meeting the construction requirements. This difference is mainly based on the different uses of water supply and drainage and the corresponding health and safety requirements. Therefore, although PE black drainage pipe may be more competitive in price, due to its use of recycled materials, it sacrifices its hygiene and safety to some extent and is mainly suitable for non-drinking water occasions, such as drainage systems.
Application of Black drainage pipe in the municipal drainage system
Black drainage pipe plays an important role in municipal drainage. This type of drainage pipe is mainly made of polyethylene (PE) material, which has many advantages, making it an ideal choice for municipal drainage systems. First of all, PE material is high-strength, non-toxic, environmentally friendly corrosion-resistant, and is not easy to rust, so it has become a substitute for iron water pipes. The corrosion resistance of this material enables it to resist the erosion of chemical substances and is suitable for various complex municipal drainage environments.
In the municipal drainage system, the role of Black drainage pipe is mainly reflected in efficient drainage, which can quickly drain rainwater or sewage and prevent urban waterlogging and groundwater pollution. Its smooth inner wall and small inner wall friction resistance help to improve the water delivery efficiency and further enhance the performance of the drainage system.
Function and advantages
The main functions and advantages of Black drainage pipe include extended service life, reduced algae attachment, easy concealed installation, economical, corrosion-resistant, efficient water saving, reduced maintenance and replacement costs, easy installation and maintenance, and a wide range of applications.
The reason why black drainage pipe is widely used is mainly because of its multiple advantages.
1. The black appearance can effectively absorb heat from sunlight, reduce the reflectivity of light, and slow down the aging of the material, which means that it can better resist damage caused by ultraviolet rays, thereby extending its service life.
2. Black can also reduce the attachment and growth of algae and other microorganisms, which is very important for keeping pipes clean and reducing maintenance requirements.
3. HDPE Black drainage pipe’s corrosion resistance is also one of its advantages. It can resist the erosion of chemicals and soil acids and alkalis, has a long service life, and reduces the cost of maintenance and replacement.
This pipe is light and easy to bend, making installation and layout simple and quick. Its design also makes cleaning and maintenance relatively easy, ensuring the long-term stable operation of the drainage system.
