The allowable deviation of diameter (schedule 20 and greater) at any point from nominal diameter is: Under 2": +.015/-.031 2"-12": +/-1%
The straightness tolerance for schedule 40 pipe, according to industry standards like ASTM and ASME, generally allows for a deviation of 1/8 inch per 10 feet of pipe length. This means that, for a standard length of 20 feet, the maximum allowable deviation from a straight line would be 1/4 inch. However, specific tolerances may vary based on the application and manufacturer, so it's important to consult relevant specifications for precise requirements.
The circumference of a 4-inch Schedule 40 pipe can be calculated using the formula for the circumference of a circle: ( C = \pi \times d ), where ( d ) is the outside diameter. A 4-inch Schedule 40 pipe has an outside diameter of approximately 4.5 inches. Therefore, the circumference is about ( 3.14 \times 4.5 \approx 14.13 ) inches.
Assuming the 80 inch is the outside measurement and not the internal bore size. Formula is Circumference = radius squared timed by pi (3.1416) 40 × 40 × 3.1416 = 5026.56 inches
The number of fixture units that a 4-inch horizontal pipe can accommodate varies based on plumbing codes and the type of fixtures connected. Generally, a 4-inch pipe can handle around 40 to 50 fixture units, depending on factors like the length of the pipe and the specific code provisions in your area. To get an accurate assessment, it's best to consult local plumbing codes or a plumbing engineer.
The takeout of a 6-inch schedule 40 PVC 45-degree fitting is the distance between the two ends of the fitting. For a 6-inch fitting, the typical takeout is about 6 inches, but it can vary slightly depending on the manufacturer. This measurement is crucial for ensuring proper alignment and fit in piping systems. Always refer to specific manufacturer specifications for the most accurate dimensions.

The psi rating for schedule 40 PVC pipe is typically around 480 psi.
The schedule of a pipe indicates its thickness. The higher the schedule number, the thicker the pipe will be. Shcedule 40 and schedule 80 seem to be the most common.
No, Schedule 20 PVC pipe is not thicker than Schedule 40. In fact, Schedule 40 PVC pipe has a thicker wall and can support higher pressure compared to Schedule 20. Schedule 20 is typically used for drainage and venting applications, while Schedule 40 is suited for higher-pressure systems like water supply.

Steel pipe that is schedule 40, means that the steel pipe has a certain amount of threads on it. It also means that it can't be longer than about 10 feet.
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.
The recommended pressure rating for 1.5 inch schedule 40 pipe is 130 psi.
Not plumbing pvc pipe, but pvc pipe made especially for wiring.
PVC stands for Polyvinyl Chloride. The 40 means schedule 40, refers to the thickness of the walls of the pipe.
