The threaded fitting dialog window is opened by selecting in the menu 'Tables' > 'Threaded Fittings'. The input data for the threaded fittings is edited in this window. The data of the threaded fittings is stored in the project database. Threaded fittings are attached partly inside or outside on a pipe. They are usually of smaller size compared to butt-welded components. The ports of the fittings range from 1 to 4.

The reference properties in this window are as follows:

  • 'Project Number', to show the current project number for reference only. The field is not editable, the project number is edited in the project dialog.
  • 'Pipe Class', to show the current pipe class for reference only. The field is not editable, the pipe class number is edited in the pipe class dialog.

In the window the threaded fitting types are:

  • 'Bushing', a fitting on which the external thread is larger than the internal thread to allow two pipes of different sizes to be connected.
  • 'Cap', a fitting externally attached to the end of a pipe.
  • 'Coupling', a fitting to join two pipes of the same size.
  • 'Half-Coupling', a fitting that is only threaded at one end. The other end is welded or otherwise fastened to a pipe.
  • 'Cross', a fitting with 4 ports having one inlet and three outlets or vice versa).
  • 'Elbow (90 degrees)', a fitting to connect pipes of same diameters to change the direction of the flow.
  • 'Elbow (45 degrees)', a fitting to connect pipes of same diameters to change the direction of the flow.
  • 'Y-type Elbow', a fitting with 3 ports in which the side inlet pipe enters at a 45-degree angle.
  • 'Street Elbow', same as an elbow, but one end is a long male connection that can be connected directly to another fitting.
  • 'Union Elbow', same as a union and to change the direction of the flow.
  • 'Bend (90 degrees)', same as an elbow, but with a longer curvature radius for smoother flow.
  • 'Nipple', a fitting as a short stub of pipe which connects two other fittings.
  • 'Swage Nipple', same as a nipple, but is concentric or eccentric connecting pipes of different diameters.
  • 'Plug', a fitting that fits inside a pipe or a fitting.
  • 'Tee', a fitting to connect pipes of different diameters or change the direction of the flow.
  • 'Union', same as a coupling, but allows future disconnection of the pipes for maintenance.
  • 'Outlet', generic term for various types of fittings attached to a hole in a pipe.

In the window the fitting properties are as follows:

  • 'Standard' (dropdown box in schedules, ratings and series), to select the dimension standard for the fitting.
  • 'Class', to select the pressure class for the fitting.
  • 'Material', to show the material selected. The material can be edited by clicking the button next to the field. A new window will be opened to show the available material.
  • 'Tolerance', to show the tolerance as per pipe class setting. The tolerance can be overwritten to set individual data per component.
  • 'Corrosion Allowance', to show the corrosion allowance per pipe class setting. The corrosion allowance can be overwritten to set the individual data per component.
  • 'No. ports', number of attached pipes ranging from 1 to 4. The number is for reference only. The field is not editable.
  • 'Type of thread', thread type used for the fitting.
  • 'Options', optional property for the fitting depending on the type of fitting.
  • 'Note reference', to set a note for the fitting.
  • 'Commodity code', to set the commodity code per component or group of components.

In the window the port definition properties are as follows:

  • 'Number', the number of the port attached to a pipe.
  • 'Type', the kind of connection, default here is 'Threaded', but can be changed to, 'Butt Welding', 'Socket Welding', or 'None'.
  • 'Shape', the kind of end attached to a pipe.
  • 'Angle', angle in degrees to the connected pipe.

At the bottom of the dialog:

  • 'OK' button, to save the data to the pipe class database and close the dialog.
  • 'Cancel' button, to close the dialog without saving the data.
