What is Schedule 40 black pipe?
These welded steel, schedule 40 pipes feature NPT threads at both ends. Black steel pipe is interchangeable with black cast-iron or black malleable iron pipe. Galvanized pipe is zinc-coated to resist rust and corrosion. Use in low-pressure plumbing applications including air, water, oil, natural gas, and steam.
Is PVC conduit considered rigid?
Tough, durable, with high tensile strength, yet easy to handle and install right on the jobsite. Schedule 40 & 80 rigid PVC conduit systems are sunlight resistant and are used exposed, encased in concrete, concealed in walls and in direct burial applications including systems for: Utilities.
Does Schedule 40 PVC bend?
PVC pipe is commonly used as electrical conduit as well as irrigation piping. It's rigid and strong, which doesn't allow it to bend at all.
Is Schedule 40 pipe flexible?
This flexible Schedule 40 PVC pipe permits compound curves, greatly reducing the number of fittings otherwise required. It also reduces friction loss caused by elbows. Standard Schedule 40 or 80 PVC fittings can be used. A special solvent cement (235) is required (do not use purple primer—use acetone as a pipe primer).

Inside Diameter of Schedule 40 vs Schedule 80
- If the pipe were the same color, it would be difficult to tell the difference from the outside. In fact, both schedule 40 and schedule 80 PVC pipe have the same outside diameters. So a 1" size sch 40 PVC pipe has the same O.D. as a 1" sch 80 PVC pipe. The difference is in the inside diameter or I.D. of the pipe. Schedule 80 PVC pipe will have a smaller inside area than Schedule 40 pipe bec…
Weight & Price
- Two other factors that may play into which schedule PVC you choose are weight and price. Since schedule 80 PVC has a thicker wall, it is heavier than comparable schedule 40 pipe and fittings. That generally makes it more pricey to ship and more difficult to handle when installing large size pipe and fittings. Schedule 80 PVC is also more expensive than schedule 40 because it requires …
Other Schedules & Materials
- PVC is most commonly found in schedule 40 and 80, but schedule 120 PVC pipe exists also. This is an even thinner wall pipe than schedule 40. These schedules are applied to other materials, too.
