Use this dialog box to specify which design parameters to analyze for a specific pressure pipe network.
-
Deflection
- Checks the pressure network for the allowable deflection angle between pipe joints, pipes and fittings, or two fittings.
Note: The allowable deflection is specified in the pressure network parts list when you add sizes (the default allowable deflection value provided for the part in the part catalog can be changed when adding the part to the parts list).
-
Diameter
- Checks that connections between any two components (pipes, fittings, or appurtenances) are of equal diameter.
Note: The Diameter validation option uses the nominal diameter, not the inner or outer diameter.
-
Open Connections
- Checks for open connections in the pressure network. Pressure networks are closed systems by design. This check can be used to identify unintentional breaks in the system, where parts appear to be connected but may be separated by slight gaps.
-
Radius of Curvature
- Checks the pressure network for the allowable radius of curvature which describes how much the pipe can curve, bend, or flex. The allowable radius of curvature is specified in the pressure network parts list when you add sizes.
Note: This check analyzes the pipe network for actual radius of curvature as well as effective radius of curvature. Deflection across many consecutive, equal lengths of pipe can be expressed as an effective radius. Instead of drawing the consecutive, equally deflected lay lengths of pipe, you may choose to calculate the effective radius and draw an arc. This is different than modeling flexible pipe, which has a specific property that defines the limit of its curvature. Drawing a curved pipe when the
Minimum Flex Radius = zero enables you to draw a curve to approximate a series of rigid, deflected pipes. For more information, see
To Insert Curved Pressure Network Segments.
