Schedule 40 vs 80 Steel Pipe Thickness

Schedule 40 and 80 are both standards for pipe wall thickness grades in ANSI/ASME B36.10M. In the case of the same specifications, Schedule 80 is not only thicker than Schedule 40, but also has a stronger pressure bearing capacity, and is also heavier and more expensive. Schedule 40 is suitable for low-pressure environments such as water pipes and HVAC systems, while Schedule 80 is commonly found in industrial high-pressure pipelines.
