Minimum Pipe Length

Configuration variables OPM_MINIMUM_PIPE_LENGTH sets the minimum pipe length for the pipe. For example, if the value is set to 1,1 it means all the pipes with a diameter greater than or equal to 1 will have minimum length = 1 in. It supports multiple semi-colons separated settings.

Placement

Pipe can only be created up to the minimum length defined in the variable.

Drag Manipulators

Pipe can be dragged only up to the minimum pipe length.

Connected component drag operation

  • The component connected to the pipe can be dragged up to the minimum length of pipe if there is an adjacent component on the other end
  • The component can be dragged to the very end of the pipe and can be connected to the adjacent component on the other end by pressing the shift key and then clicking the drag manipulator
  • If there is no adjacent component, pipe less than the minimum length is deleted after the component's drag operation

Inline Placement:

Tee and some other components can be placed as an inline component Place a pipe in OPM of appropriate length and start Tee placement after selecting the pipe. Following scenarios can exist in this case:

  • if there is an adjacent component at the end of the pipe and the pipe to be created between tee and adjacent component is less than the minimum pipe length, Tee is set at the end of the pipe and is connected to the adjacent component
  • If there is no adjacent component, the pipe is deleted if the length is less than the minimum pipe length defined

Error Message

A warning message similar to the example below will display in the message center if the pipe length is less than the minimum length specified by the configuration variable OPM_MINIMUM_PIPE_LENGTH.

Minimum pipe length allowed is <Minimum Pipe Length value set in configuration variable> <Working unit> for <Pipe Daiameter> <Working unit>

Example, Minimum pipe length allowed is 1 IN for 4 IN nominal diameter.

Branch Pipe

In the placement of branch pipe on header pipe, minimum distance to allow tee placement is calculated through:

minimum distance = TeeHalfLength + minimum pipe length

Break Pipe Command

A error message similar to the example below will display in the message center if the pipe is broken within the minimum pipe length specified by the configuration variable OPM_MINIMUM_PIPE_LENGTH.

Cannot break pipe within the minimum pipe length defined
