The Pipes tab fields allow you to document pipe details. The data in the Pipe Shape, Diameter, Pipe Width, Length, Length Status, Material, Slope, Surface, and Liner fields is carried over by the system when a US Structure is selected in the header. This data comes from the corresponding Pipe Inventory record. These fields will remain empty if they were not populated in Pipe Inventory. Several of these fields have special functions. These are described in the table below.

Special Functions |
Pipe Shape
|
The Pipe Shape field features a pre-defined list of shapes. Although you can add shapes to the list and modify them, you cannot modify any of the pre-defined shapes in the list. |
Dia/Height (in) |
Use this field to enter the diameter of a round pipe in inches. If the pipe is not round, enter the height in inches. |
Pipe Width |
The Width field is only enabled when the pipe shape (as defined in the Pipe Shape field) is not round. |
Length (ft) |
The length of the pipe from the center of the upstream manhole to the center of the downstream manhole. This field is calculated by the system in the Pipe Inventory record. |
Length Status |
The source the length information originates from. This could be GPS points, record drawings, or surveying. This field is not editable by the user. |
Slope %
|
The Slope % field is a calculated field. Slope refers to the vertical displacement along the length of the pipe with respect to the horizontal displacement along the length of the pipe (otherwise known as the rise/run). The slope, calculated by pressing F5, appears as a percent. You can also manually enter a percent in this field. If the active invert elevations are greater than three (>3) and length is greater than zero (>0), then the slope is calculated by the following equation: If either invert is less than three (<3), or the length is zero (=0), the slope is retrieved from the minimum pipe slope table. |
