Yes and it can be schedule 80 and schedule 120
I don't think 6 inch pipe is available in schedule 30.
Schedule 40 black iron pipe is available in various sizes, typically ranging from 1/8 inch to 6 inches in nominal diameter. The outside diameter (OD) varies depending on the nominal size, with a 1-inch nominal pipe having an OD of approximately 1.315 inches. The wall thickness also varies; for a 1-inch Schedule 40 pipe, it is about 0.133 inches. This standard sizing is used for various applications, including gas and water distribution.
What schedule pipe?
A 4-inch Schedule 80 steel pipe has an approximate inside diameter of 3.68 inches. Therefore, a pipe that would fit inside would need to have a diameter smaller than this value. Typically, a 3-inch Schedule 40 pipe, which has an outside diameter of 3.5 inches, would fit inside the 4-inch Schedule 80 pipe.
The recommended pressure rating for 1.5 inch schedule 40 pipe is 130 psi.
The maximum pressure rating for a 2 inch schedule 80 PVC pipe is typically around 400 psi.
The maximum weight capacity that can be supported by a 2 inch schedule 40 PVC pipe is approximately 250 pounds.
No
The pressure rating for schedule 80 pipe is typically around 200 psi (pounds per square inch).
The circumference of a 6-inch schedule 40 pipe can be calculated using the formula ( C = \pi \times d ), where ( d ) is the outside diameter. For a 6-inch schedule 40 pipe, the outside diameter is approximately 6.625 inches. Thus, the circumference is about ( C \approx \pi \times 6.625 \approx 20.82 ) inches.
Schedule 10 , 40 and 120
YES there is
