Conduit pipe, 4.0 meters long with an outer diameter (OD) of 24.5 mm and an inner diameter (ID) of 18 mm, is typically used to protect and route electrical wiring within buildings or other structures. The outer diameter represents the total width of the pipe, while the inner diameter indicates the space available for cables or wires to pass through. These pipes, often made from materials like metal or PVC, provide mechanical protection to the wiring, shielding it from impact, moisture, and other environmental factors, while also helping to organize and secure the routing of wires in various installations.
