Difference Between Schedule 40 and 80

Schedule 40 vs 80

“Schedule 40” and “Schedule 80” refer to the thickness of the walls of pipes. “Schedule” is the standard of wall thickness that has been adopted by the American National Standards Institute. As per the Institute, the thickness of wall pipes varies from Schedule 10, Schedule 40, Schedule 80, and Schedule 160.

Pipes with Schedule 40 come with standard weight, and pipes with schedule 80 come with extra strength. The materials used for making Schedule 40 and Schedule 80 come from the same material.

Schedule 80 pipes have a thicker wall than Schedule 40 pipes. As such, Schedule 80 pipes are stronger than Schedule 40 pipes. Though both pipes are used in construction work, Schedule 40 is used more often. But if a stronger pipe was needed, then the engineers would go for Schedule 80 pipes. Schedule 80 pipes are used where the pipes have to be exposed. But if there is no need for any extra strength, Schedule 40 pipes are sufficient.

Schedule 40 and Schedule 80 pipes are also different in their cost. As Schedule 80 pipes consist of more materials, the price is considerably higher than Schedule 40 pipes. Schedule 80 pipes are also more costly as the cost of production is greater.

When comparing the weight, Schedule 40 pipes come in less weight than Schedule 80 pipes. As such, Schedule 40 pipes are easier to install than Schedule 80 pipes.

If there is a need for a high water temperature or high-pressure pipe, Schedule 80 is the best as it can withstand a greater pressure and temperature than Schedule 40 pipes.

Summary:

Pipes with Schedule 40 come with a standard weight, and pipes with Schedule 80 come with extra strength.
Schedule 80 pipes are stronger than Schedule 40 pipes.
Though both pipes are used in construction work, Schedule 40 is used more often.
