Schedule 40 and schedule 80 pipe are made from the same material. The difference in structure lies in the thickness of the pipe wall; the higher the schedule, the thicker the wall of the conduit.
What is the pipe schedule?
The pipe schedule refers to the thickness of the walls of a steel pipe. Pipe schedules are denoted by a number, which is based on the thickness of the pipe's walls. The schedule number does not correspond directly to the pipe's actual wall thickness but rather to a set of standardized thicknesses. These standardized thicknesses were established by the American National Standards Institute (ANSI) and are based on a formula that takes into account the pipe's nominal size and its pressure rating.
What is Schedule 40?
Schedule 40(Sch 40),such as Schedule 40 seamless pipe,in a pipe indicates tensile strength, 40 kg pressure. It is indicated by a standard thickness of 4.0 mm.
What is Schedule 80?
Schedule 80(Sch 80), such as Schedule 80 seamless steel pipe, in a pipe indicates tensile strength, 80 kg pressure.
Schedule 40 VS. Schedule 80 pipe
Wall Thickness - Schedule 80 pipes have a thicker wall than Schedule 40 pipes for the same NPS. The increased wall thickness makes Schedule 80 pipes more robust and able to handle higher pressure and heavier loads.
Weight - Schedule 40 pipe weight depends on its length and material composition, but it is less than Schedule 80 pipe weight due to the thinner wall.
Pressure Rating - Due to its comparatively thinner wall, Schedule 40 pipe has a lower pressure rating than Schedule 80 pipe.
Schedule 80 pipes can withstand higher pressure and are commonly used in heavy-duty applications.
Cost - When it comes to cost, Schedule 40 plumbing parts are typically more affordable than those made with Schedule 80. The reason behind the price difference is that Sch 80 has a thicker sidewall than Sch 40, which requires more material to manufacture. Additionally, Sch 80 pipes often come with colorant added, which also increases production costs.
