Purpose
The dialog is used to select the rating and materials of threaded cap components. There is no drawing of the threaded cap components and the dimensions can
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.
The dialog shows a list of threaded cap components per line size.
Figure: threaded caps dialog
The following data fields are available:
- 'Table', a list of selectable threaded caps with the main properties. Each row represents one threaded cap. Select one or more rows and use the other fields to set the properties.
- 'Standard', the threaded cap standard for one or more caps.
- 'Rating', list of available selectable ratings according the standard.
- 'Material Standard', the material standard of one threaded cap. Use the buttons to change or remove a material standard for one or more threaded caps. For further information see PCC material selection window.
- 'Dimension Standard', the dimension standard of one threaded cap. Here, this standard is read-only and can not be changed, because it is the used threaded cap standard. For further information see PCC dimension selection window.
- 'Schedule/Rating', the rating to classify the strength of one threaded cap. Here, this rating is read-only and can not be changed, because it is the selected threaded cap rating.
- 'Description', the description of one threaded cap. Use this field for one or more threaded caps. 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 threaded cap. Use this field for one or more threaded caps. This field is only used for reporting.
- 'Commodity code', the commodity code of one threaded cap. Use this field for one or more threaded caps. This field is only used for reporting.
- 'Weld joint quality factor z, E', the value for the weld joint factor of one threaded cap. Use this field for one or more threaded caps. 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 W', select the material category that will set the value for the weld joint strength reduction factor W of one or more threaded caps. 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.
- 'Coefficient Y', select the material category that will set the value for coefficient Y of one or more threaded caps. The value for Y 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 threaded caps. 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.
