Description
The SDR (Standard Dimension Ratio) on PVC pipes indicates the relationship between the pipe's outer diameter and wall thickness. It is calculated by dividing the pipe's outer diameter by the wall thickness. A lower SDR means thicker walls and higher pressure capacity, while a higher SDR indicates thinner walls and lower pressure capacity.
For example, a 2-inch diameter, 6-meter long SDR 50 PVC pipe is a common choice for sanitary systems due to its strength and durability.
SDR is crucial for selecting appropriate pipes based on the pressure and application required in hydraulic and sanitary systems.
