It is wise to not mix schedule 40 and schedule 80 parts and pipes in one project, as they have different fit tolerances as well.īesides rigidity, schedule 80's thicker wall also allows for a greater amount air or water pressure to flow through the pipe. Schedule 80 PVC has a thicker wall, dark gray in color, and is used for commercial and industrial applications. Schedule 40 PVC is typically white, and used for residential and irrigation purposes. The two most common schedules are 40 and 80.

The wall thickness of your pipe and fittings is called the schedule.

Be sure you're ready to carry big bulky pipes. Larger diameters are also quite heavy and cumbersome. The larger diameters are great for making structures or furniture because they will not bend and are very difficult to sheer. The smaller diameters bend and flex easily but still maintain some strength - good for hoop houses and gardening projects. As the pipes increase in diameter, so does the inner wall thickness, making them stronger and more inflexible. This makes thin tubes really useful for lightweight applications and small structures, but poorly suited to standing up to heavy loads because the pipe will flex.

The larger the pipe size, the more rigid and less flexible it will be. You have lots of options when it comes to PVC pipe sizes, the most common are 1/2', 3/4', 1', 1 1-/4', and 2'. PVC is even available in thin, flexible fabric which makes it ideal for sewing projects (think rain jackets and water resistance). This course mainly discusses how to work with PVC pipe, but the plastic is available in sheets, rods, and more.
