250mm HDPE Pipe
The 250mm HDPE pipe is a robust, durable solution used in various applications, including water supply systems, sewage systems, industrial fluid transport, and irrigation. It offers a wide range of pressure ratings, making it suitable for both low and high-pressure systems. Below is a comprehensive breakdown of the 250mm HDPE pipe, its pressure ratings, technical specifications, and common uses.
Explanation of Pressure Ratings
4 kg/cm²: Suitable for low-pressure applications such as irrigation, residential water systems, or non-potable water transport.
6-10 kg/cm²: Typically used for municipal water distribution, light industrial applications, and pressurized irrigation systems.
12.5-16 kg/cm²: For medium to high-pressure applications, such as potable water supply, firefighting systems, or industrial fluid transport.
20-32 kg/cm²: For high-pressure applications, such as oil & gas pipelines, chemical transport systems, and large-scale industrial fluid systems.
As the pressure rating increases, the wall thickness also increases to support higher pressures.
Wall Thickness and SDR
The Standard Dimension Ratio (SDR) defines the relationship between the pipe’s outer diameter and wall thickness. Lower SDR values correspond to thicker walls and stronger pipes, which are needed for higher pressure systems.
| SDR Value | Approximate Wall Thickness (for 250mm pipe) |
|---|---|
| SDR 11 | ~ 22.0 mm |
| SDR 17 | ~ 16.0 mm |
SDR 11: Provides thicker walls suitable for higher pressure systems (e.g., 16-32 kg/cm² pressure ratings).
Applications
The 250mm HDPE pipe is commonly used in several industries for different applications, including:
Water Distribution Systems: For potable and non-potable water networks, particularly in medium-to-high-pressure systems.
Sewage and Drainage: For stormwater, sewage transport, and waste treatment systems.
Irrigation Systems: For transporting water under pressure in agricultural irrigation systems.
Industrial Fluid Transport: Ideal for transporting chemicals, industrial liquids, or slurries in manufacturing plants, refineries, and chemical processing facilities.
