The friction factor is a measure of the resistance that a fluid experiences when flowing through a pipe. This resistance can vary greatly depending on the pipe's material, surface roughness, diameter, and flow rate. For galvanized iron pipes, the friction factor is crucially important because it directly affects the flow efficiency, energy consumption, and overall performance of the piping system. Higher friction factors lead to increased energy costs and reduced flow rates, making it essential for suppliers to understand how these factors interact.
Sewer jetters operate by connecting a high-pressure hose to a specialized nozzle that directs the water flow in a forward and backward motion. The nozzle can be inserted into the sewer line through a cleanout or access point, and the high-pressure water is then pumped through the hose to break up blockages. The force of the water can reach up to 4000 PSI (pounds per square inch), making it highly effective at cleaning even the toughest obstructions.
