Explanation of Nominal Sizes and Wall Thickness
Nominal Pipe Size (NPS) identifies standardized pipe sizes. It represents the approximate pipe diameter. NPS does not show exact inside or outside diameter. The outside diameter (OD) stays constant for a given NPS. Wall thickness varies with the schedule number. This affects the pipe’s internal diameter. Schedule 10 pipes have relatively thin walls. They are thinner than Schedule 40 and Schedule 80. Thinner walls make Schedule 10 pipes lighter. They are easier to handle but not for high-pressure use.
Comparison with Other Schedules (Schedule 40, Schedule 80)
Schedule 10 vs. Schedule 40:
Schedule 10 pipes have thinner walls compared to Schedule 40 pipes. This makes Schedule 10 pipes lighter and less expensive but also less durable under high pressure.
Example: A 1-inch NPS pipe with Schedule 10 has a 0.109-inch wall thickness. Schedule 40 for a 1-inch NPS pipe has a 0.133-inch wall thickness.
Schedule 10 vs. Schedule 80:
Schedule 80 pipes have thicker walls than Schedule 10 pipes. This provides greater strength and pressure resistance. For a 1-inch NPS pipe, Schedule 80 has a 0.179-inch wall thickness. Schedule 10, in contrast, has a 0.109-inch wall thickness. Choosing the right schedule depends on application requirements. Consider pressure and environmental conditions for selection.
