Definition - What does Bypass Diameter mean?
The bypass diameter is the total amount of space in a pipe which will allow flow, a bypass plug or similar equipment. The bypass diameter can range from a few millimeters to several meters depending on application, economic and geographic restraints. The bypass diameter will be affected by previous rehabilitation efforts such as lining.
Bypass diameter may also be known as inner diameter.
Trenchlesspedia explains Bypass Diameter
Along with properties of the fluid, the bypass plug and the pipe material, bypass diameter is a major contributing factor to the maximum flow rate of a pipe. Should the flow require an adjustment to the bypass diameter, there is a process by which flanges are attached to the bypass plug to adjust the flow as bypass plugs are corrosive resistant and have strong stretching and efficient sealing properties.
