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.

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.
