180mm HDPE Pipe
The 180mm HDPE pipe is another standard size in the HDPE pipe range. It is used in a variety of applications, from municipal water and gas distribution to industrial systems. Below is a comprehensive breakdown of the 180mm HDPE pipe with its different pressure ratings and key technical details.
Explanation of Pressure Ratings
4 kg/cm²: Low-pressure systems, ideal for less demanding applications, such as irrigation and basic water supply.
6-10 kg/cm²: Standard range for most municipal water supply systems, medium-pressure irrigation, and drainage systems.
12.5-16 kg/cm²: Typically used in applications where higher pressures are required, such as for municipal potable water or industrial applications.
20-32 kg/cm²: High-pressure systems, including those used for transporting liquids in chemical industries, deep-water supply systems, and oil & gas pipelines.
The wall thickness increases with higher pressure ratings, providing greater strength to withstand the internal pressure.
Wall Thickness and SDR
The Standard Dimension Ratio (SDR) is a key measurement that defines the pipe’s wall thickness relative to its diameter. Lower SDR values (indicating thicker walls) are used for higher pressure ratings.
| SDR Value | Approximate Wall Thickness (for 180mm pipe) |
|---|---|
| SDR 11 | ~ 16.0 mm |
| SDR 17 | ~ 10.5 mm |
- SDR 11: Common for higher-pressure applications, providing strength and durability to the pipe.
- SDR 17: More economical for lower pressure systems, where the pipe doesn’t need to withstand as much stress.
Applications
The 180mm HDPE pipe is versatile and suitable for a wide range of applications, including:
Water Supply Systems: Both potable and non-potable water distribution, especially in medium to high-pressure networks.
Sewage and Drainage: Used for sewer lines, stormwater systems, and drainage pipes in both urban and rural environments.
Industrial Applications: For the transport of chemicals, slurries, and industrial liquids in various industries such as pharmaceuticals, food processing, and manufacturing.
Irrigation Systems: Used for pressurized irrigation systems in agricultural settings.
