PVC - SDR 21 piping is commonly used in underground water distribution systems, particularly for potable water supply. Its durable and corrosion-resistant properties make it suitable for both residential and commercial applications. Additionally, the SDR (Standard Dimension Ratio) 21 designation indicates a specific wall thickness that allows it to withstand higher pressure, making it ideal for pressurized systems. This type of piping is also lightweight and easy to install, further enhancing its practicality for various Plumbing projects.

Damping Resistor on Inputs/Outputs (R)Series damping resistors (SDR), denoted by R in the device number, are included at all input/output and output ports of designated devices (see Figure below). The SDRs limit the current, thereby reducing signal undershoot and overshoot noise. Additionally, SDRs make line termination easier, which improves signal quality by reducing ringing and line reflections.This tutorial is based on the Understanding and Interpreting Standard Logic Data Sheets application report (SZZA036).

SDR 23.5 pipe refers to a specific type of polyvinyl chloride (PVC) or high-density polyethylene (HDPE) pipe characterized by its Standard Dimension Ratio (SDR) of 23.5. The SDR value indicates the relationship between the pipe's diameter and its wall thickness, with lower SDR values signifying thicker walls and greater pressure resistance. SDR 23.5 pipes are commonly used in applications such as water distribution systems and are designed to handle moderate pressure levels.

The maximum operating pressure for a 3-inch diameter SDR 17 PVC water pipe is typically around 150 psi (pounds per square inch). This pressure rating can vary slightly depending on the specific manufacturer and standards, so it's always advisable to consult the manufacturer's specifications for precise values. SDR (Standard Dimension Ratio) indicates the pipe's wall thickness relative to its diameter, with lower SDR numbers corresponding to thicker walls and higher pressure ratings.
