a 4″ would be around 12.56
Should be 5″ which would be 15.70 Circumference
a 6″ pipe would be around 18.85

ParticipantHe was correct for the information you gave, you just gave bad data. We can only work from the information we are given. In the computer business it is known as “GIGO”. Garbage In, Garbage Out.

ParticipantI hit the wrong button too soon. Anyway he was almost correct since he gave the measurements for the inside of the pipe and you probably wrapped the string around the outside. 4″ should be about 13 3/4″ depending on the wall thickness

I just took the measurements out of the cast Iron soil pipe hand book, So I guess they also made a mis print things happen.

ParticipantSince pipe is always named by the inside diameter, the wall thickness affects the external diameter and thus the circumference. You did not mention that it was a piece of water main which has thick walls and thus a larger circumference than soil pipe. Again, without proper input our answers cannot be correct. But come back anytime.

ParticipantSwabbie. I too would be guilty of believing that you were talking about Soil pipes, as:
the question was posted on the Drainage section. The pipe emanated from the floor. Please forgive our jumping to conclusions, we should ask more questions before answering.
