Schedule 80 PVC pipe is used for applications that require higher pressure and temperature resistance compared to Schedule 40 PVC pipe. Common applications include industrial processes, chemical handling, water treatment systems, and underground installations where durability and strength are important.
Black steel pipe is commonly used in industrial applications for transporting gas, oil, and water, as well as for structural support in buildings and infrastructure.
Schedule 40 PVC is a type of plastic pipe that is commonly used in plumbing and construction projects. It is known for its durability, affordability, and ease of installation. In plumbing, Schedule 40 PVC is used for water supply lines, drainage systems, and vent pipes. In construction, it is used for electrical conduit, irrigation systems, and other applications where a strong and corrosion-resistant pipe is needed.
Chore Pad and Chore Hero are two applications that can be used to schedule everyday chores.
Schedule 40
In plumbing jargon, "schedule 40" refers to the thickness of the pipe wall. Specifically, it indicates a standard measurement for the thickness of PVC (polyvinyl chloride) pipes and fittings. Schedule 40 pipes are commonly used for residential and commercial plumbing applications due to their durability and ability to withstand high pressure.
The internal diameter (ID) of a 32 NB (Nominal Bore) pipe is approximately 40.0 mm. Nominal Bore is a designation used to describe the size of the pipe, but the actual internal diameter can vary slightly depending on the pipe's schedule or wall thickness. For precise applications, it's essential to refer to the relevant standards or specifications for the specific type of pipe being used.
The schedule value refers to the thickness of the wall of the pipe; the bigger the number (schedule) the bigger the wall thickness is of the pipe. The thickness is relative to the diameter of the tube/pipe an the application it is being used in.
Use only black pipe
The presence of the NSF designation on pipe means it was tested for compliance with one or more voluntary national standards. Common designations include NSF-pw and NSF-61, both of which mean the pipe is intended for potable water applications. Pipe displaying NSF-dwv should only be used for drain, waste or vent applications.
Schedule 40 Foam Core pipe can be used for DWV systems, and Schedule 40 pressure rated pipe (PW) should be used for water lines, and can also be used for DWV. CPVC can also be used for water lines.
In the electrical industry there are two grades of PVC conduit. Schedule 40 and Schedule 80. The code designates that schedule 80 be used in above ground construction and schedule 40 and/or schedule 80 be used in acceptable underground applications.
