In PipeView, you can add or update the following mainline settings:

• The mainline description
  
  
• Whether the mainline is enabled or disabled
  
  
• The design flow value for that mainline
  
  
• Either time or pressure as the type of flow stabilization management for that mainline
  
  
• The flow stabilization value as either a unit of time or a measure of psi
  
  
• Whether the mainline is managed by flow
  
  
• The flow variance percentage and whether or not to shut down if the flow variance percentage is exceeded
  
  
• Either time or pressure as the type of mainline delay option for that mainline
  • The delay before the first zone either by time or psi
  • The delay between zones either by time or psi
  • The delay after the last zone either by time or psi
  • The number of zones to run between delays
    
    
• Whether or not to enable or disable advanced flow variance
  • Define the values for each advanced flow variance range
  • Define whether or not to shut down if a flow variance is exceeded
