Selection of sewage pipe diameter
Thread Content
What diameter should the sewage pipeline have? What is the specific calculation method? Thank you!
There is no strict rule for this; the size of the pipe simply determines how long it takes to drain the waste. Generally, for pipes smaller than 2“, use a drain of 1”; for pipes larger than 2“, 1 1/2“ will suffice. For particularly large pipes, it can be increased appropriately.

Provided by the original poster: Unless there are special requirements, the minimum size of the vent and discharge valves should be selected according to the following principles: Container volume (m3) – Vent valve size (inches) – Discharge valve size (inches): < 1.5: 1, 1; 1.5 – 6: 1, 1.5; 6 – 17: 2, 2; 17 – 70: 2, 3; > 70: 2, 3
Generally, 2-inch ones are used. In cases where the oil is quite thick or not very clean, or when it hasn’t been treated, 3-inch ones can be used.
