Large Diameter Pipes are designed to carry more fluids or gases at a given flow rate, which is a significant advantage. For example, they can carry oil, fuel, or other liquids from a refinery to a tank farm. Using this kind of pipe can also help prevent abrasion damage. Moreover, it can help keep the pressure down. Since the diameter of these pipes is significant, they can withstand intense weather conditions. While selecting a large-diameter stainless pipe, selecting a grade with the strength and corrosion-resistance properties required for the application is essential. If the application involves high pressures, it is better to choose a grade that has higher strength. Alternatively, a grade that has a high wall thickness can also be selected. A high wall thickness can reduce the amount of traffic passing through the system.
