C900 PVC pipe (polyvinyl chloride pipe) is a common plastic pipe widely used in water treatment, drainage systems, irrigation and construction industries. The "C900" of C900 pipe means that the pipe product complies with the US ASTM standard C900. It is designed for high-pressure systems and is usually used in water supply systems and other high-demand liquid delivery systems. C900 pipe has become an ideal choice for many industrial and civil piping systems due to its corrosion resistance, lightness, easy installation and long service life. This article will introduce c900 pvc pipe dimensions and its application characteristics in detail.
c900 pvc pipe dimensions are mainly determined by its outer diameter and wall thickness. According to the US ASTM standard C900, C900 pipes are divided into different nominal diameters (NPS, Nominal Pipe Size), and the corresponding outer diameter, wall thickness and pressure level are specified. The following are the common C900 PVC pipe size standards:

C900 PVC pipe is usually designed for high-pressure environments, and its pressure rating is usually 305 psi (about 2.1 MPa), which means it can withstand greater water flow pressure. Therefore, C900 pipe is particularly suitable for areas that need to withstand higher water pressure, such as urban tap water supply systems, industrial water treatment and other high-pressure liquid transportation.
1. Corrosion resistance: C900 PVC pipe is made of polyvinyl chloride material and has excellent chemical corrosion resistance. It will not rust or corrode like metal pipes, so it is very suitable for environments with long-term contact with water or other liquids. It has been widely used in fields such as chemical transportation, wastewater treatment and water supply pipelines.
2. Lightness and convenience of installation: Compared with metal pipes such as steel pipes, C900 PVC pipes are lighter and easier to transport and install. This lightness can not only reduce labor intensity, but also effectively reduce construction costs. The connection method of C900 pipe is usually rubber ring connection or fusion joint, which is easy to operate and reduces the construction period.
3. Long life: C900 PVC pipe is very durable, can withstand harsh environmental conditions, and has a long service life. It has strong tolerance to environmental factors such as ultraviolet rays, oxygen, and moisture, especially in underground environments, and can be used stably for a long time.
4. Strong pressure resistance: C900 PVC pipe has high pressure resistance and can withstand high water pressure to ensure the stability of the pipeline system. It is especially suitable for large-scale water conservancy projects and industrial pipeline systems.
5. Wear resistance: The inner wall of C900 PVC pipe is not easily worn under long-term water flow, and the fluid will not generate large friction resistance when passing through, which helps to improve the transportation efficiency of the pipeline system.
1. Urban water supply system: The corrosion resistance and pressure resistance of C900 PVC pipe make it an important pipe material for urban water supply system. It can ensure the long-term delivery of clean drinking water, especially suitable for high-pressure water supply areas.
2. Industrial water treatment: In the industrial production process, C900 PVC pipe is often used to transport treated water or wastewater. Its chemical corrosion resistance is particularly suitable for treating liquids containing chemical components.
3. Agricultural irrigation: C900 PVC pipe is also widely used in agricultural irrigation systems, especially in large-scale irrigation projects. Its high pressure resistance can ensure the normal operation of irrigation pipes under high pressure conditions.
4. Fire protection system: The pressure resistance and high temperature resistance of C900 pipe make it also commonly used in some fire protection pipeline systems to ensure stable and safe water flow in emergency situations.
5. Drainage and wastewater treatment: C900 pipe is also widely used in building and municipal drainage systems, especially in sewage treatment and drainage systems. It can withstand high liquid pressure and prevent the external environment from eroding the pipes.
1. Although C900 PVC pipes have a long service life and durability, they still need regular inspection and maintenance during long-term use to ensure that their performance is not affected. Here are some maintenance suggestions:
2. Check the pipe regularly: Check whether the pipe has cracks, leaks or other damage, especially in a high-pressure environment, any minor damage may cause bigger problems.
3. Clean the inner wall of the pipe: After long-term use, some sediment or dirt may accumulate inside the C900 PVC pipe. Regular cleaning can keep the flow in the pipe smooth and prevent blockage.
4. Pay attention to the installation quality: The installation quality of the C900 PVC pipe directly affects the service life of the pipe. Ensure that the seal is good and the connection is tight during installation to prevent leakage.
5. Avoid high temperature environment: Although C900 PVC pipes are resistant to high temperatures, long-term exposure to extreme high temperature environments may affect the performance of the pipe. Therefore, avoid exposing the pipe to places with excessively high temperatures.
As a durable and economical pipe material, C900 PVC pipe has become an ideal choice for water conservancy projects, industrial facilities and other liquid transportation systems due to its excellent corrosion resistance, pressure resistance and easy installation. As the world's attention to environmental protection and energy conservation continues to increase, C900 PVC pipe will continue to play an important role in the future.
