Purpose
The dialog is used to edit the dimensions and the materials of the pipe components. The tab Component is used to select regular pipes for all line sizes. The tab Alternative is for alternative pipes besides the regular ones. The tab Detail dimensions is used to view a drawing of a pipe and to optionally edit the dimensions.
Description
- 'Project number', to identify the project or plant by number. The number is shown in various reports.
- 'Pipe Class', the name or number to identify the pipe class. The number is shown in various reports.
Tab sheet Component shows a list of regular pipes per line size.

The following data fields are available:
- 'Table', a list of selectable pipes with the main properties. Each row represents one pipe. Select one or more rows and use the other fields to set the properties.
- 'Standard', the dimension standard for one or more pipes.
- 'Schedule/Rating', list of available selectable schedules according the standard.
- 'Material Standard', the pipe material standard of one pipe. Use the buttons to change or remove the material standard for one or more pipes. For further information see PCC material selection window.
- 'Dimension Standard', the dimension standard of one pipe. Here, this standard is read-only and can not be changed, because it is the used pipe standard. For further information see PCC dimension selection window.
- 'Schedule/Rating', the schedule to classify the thickness of one pipe. Here, this schedule is read-only and can not be changed, because it is the used pipe schedule.
- 'Thickness', the nominal wall thickness of one pipe. Use this field for one or more pipes. When the value is customized, the field 'Schedule/Rating' will display '...'.
- 'Tolerance', the value for the tolerance allowance of one pipe. Use this field for one or more pipes. It is initially set by the default value from the pipe class settings. To change the unit of measurement see PCC unit selection window.
- 'End type', the end type of one pipe. Use this field for one or more pipes.
- 'Description', the description of one pipe. Use this field for one or more pipes. It is initially set by the default value from the pipe class settings. For further information see PCC pipe class edit window. This field is only used for reporting.
- 'Note list', a list of notes of one pipe. Use this field for one or more pipes. This field is only used for reporting.
- 'Commodity code', the commodity code of one pipe. Use this field for one or more pipes. This field is only used for reporting.
- 'Weld joint quality factor z, E', the value for the weld joint factor of one pipe. Use this field for one or more pipes. The value ranges from 1 to 0. It is initially set by the default value from the pipe class settings. When you change the material, this value can change.
- 'Weld joint strength reduction factor W', select the material category that will set the value for the weld joint strength reduction factor W of one or more pipes. The value for W ranges from 1 to 0 and is used in certain calculation codes to reduce the (weld joint) strength even further than the weld joint factor. For high design temperatures, the factor W determines the deterioration of the strength due to the temperature. This is applicable for seamless and welded pipes.
- 'Coefficient Y', select the material category that will set the value for coefficient Y of one or more pipes. The value ranges from 0.7 to 0 and is used in certain calculation codes to calculate the minimum required thickness.
- 'Material performance factor Mf', select the material category that will set the value for factor Mf of one or more pipes. The value ranges from 1 to 0 and is used in certain calculation codes to reduce the strength even further than the weld joint factor. For certain media like hydrogen, the factor Mf determines the deterioration of the strength due to the medium.
Tab sheet Alternative shows a list of alternative pipes besides the regular ones per line size.
The following data fields are available:
- 'Table', a list of selected pipes showing the main properties.
- 'Standard', the dimension standard for one or more pipes.
- 'Rating', the schedule to classify the thickness of one or more pipes.
- 'Material Standard', the material standard used for one or more pipes. Use the buttons to change or remove a material standard. For further information see PCC material selection window.
- 'Dimension Standard', the dimension standard used for one or more pipes. Here, this standard is read-only and can not be changed, because it is the used pipe standard. For further information see PCC dimension selection window.
- 'Schedule/Rating', the schedule to classify the thickness of one or more pipes. Here, this schedule is read-only and can not be changed, because it is the used pipe schedule.
- 'Tolerance', the value for the tolerance allowance of one or more pipes. To change the unit of measurement see PCC unit selection window.

- 'Commodity code', the commodity code of one or more pipes. This field is only used for reporting.
- 'Weld joint quality factor z, E', the value for the weld joint factor of one or more pipes. The value ranges from 1 to 0. It is initially set by the default value from the pipe class settings. When you change the pipe material, this value can change.
- 'Weld joint strength reductin factor W', select the material category that will set the value for the weld joint strength reduction factor W of one or more pipes. The value for W ranges from 1 to 0 and is used in certain calculation codes to reduce the (weld joint) strength even further than the weld joint factor. For high design temperatures, the factor W determines the deterioration of the strength due to the temperature. This is applicable for seamless and welded pipe.

The value for Mf ranges from 1 to 0 and is used in certain calculation codes to reduce the strength even further than the weld joint factor. For certain media like hydrogen, the factor Mf determines the deterioration of the strength due to the medium.
Tab sheet Detail dimensions shows the dimensions and a drawing of one pipe.

The following data fields are available:
- 'D0', outside diameter. To change the unit of measurement see PCC unit selection window.
- 't0', nominal thickness.
- 'L0', length (optional dimension and only used for external pressure). The drawing uses an estimated length to show the geometry.
- 'tol', thickness tolerance allowance.
The following fields are available for the drawing:
- 'Arrow', to reset the selection modus.
- 'Magnifying glass', to zoom in into the drawing.
- 'Measurement', to measure a dimension in the drawing.
- 'Save', to save the drawing to a file in DXF format.
The buttons at the bottom are:
- 'Help' button to show this help page.
- 'OK' button to close the dialog and save the data.
- 'Cancel' button to close the dialog without saving the data.
