What does schedule 10 pipe mean?

Schedule 10 pipe refers to a specific type of pipe used in piping systems, typically made of metal such as stainless steel, carbon steel, or alloy steel. The term "schedule" in pipe specifications refers to the thickness of the pipe walls.

In the case of Schedule 10 pipe, it means that the pipe has a relatively thin wall thickness compared to other schedules, such as Schedule 40 or Schedule 80. The actual thickness of Schedule 10 pipe can vary depending on the material and size, but it generally has lighter wall thickness compared to higher schedule numbers.

Schedule 10 pipe is often used in applications where high pressure is not a concern, but corrosion resistance or cost-effectiveness is important. Common applications include low-pressure water distribution, plumbing, HVAC (heating, ventilation, and air conditioning) systems, and certain industrial processes.
