By following these tasks, you can create your own piping materials classes and the rules, or options, for them.
Create a Piping Material Class
The first step in creating a piping specification is to define the piping material classes that you want. For more information, see Create a Piping Material Class.
Define Nominal Piping Diameters
You need to specify the nominal piping diameters (NPD) that are available in the piping materials class. For more information, see Define Nominal Piping Diameters.
Define Allowable Bend Angles
Specify the bend angles that are available in the piping materials class. For more information, see Define Allowable Bend Angles.
Define Allowable Pipe Bend Radii
Specify the pipe bend radii or bend radius multipliers that are available in the piping materials class. For more information, see Define Allowable Pipe Bend Radii.
Define Service Limits
Specify the temperature and the corresponding pressure that define the boundaries of acceptability for the piping materials class. For more information, see Define Service Limits.
Define Commodity Specific Service Limits
Specify the maximum temperature and pressure for a piping commodity, stock piping specialty, or stock instrument. This specification is especially needed when the maximum pressure or temperature for the object is not suitable for the full range of temperatures and pressures for the piping materials class. For more information, see Define Commodity Specific Service Limits.
Define Corrosion Allowances
Specify the corrosion allowance used in the calculation of piping commodities wall thickness where the thickness is not specifically included in the piping materials class. For more information, see Define Corrosion Allowances.
Define Interior Surface Treatments
Define the interior surface treatment based on the piping diameters and the piping materials class. For more information, see Define Interior Surface Treatments.
Define Joint Quality Factors
Define the joint quality factor (e) to use in wall thickness and branch reinforcement calculations. For more information, see Define Joint Quality Factors.
Define Takedown Parts
Specify the short codes to use for takedown parts or welds. For more information, see Define Takedown Parts.
Define Port Alignments Per Spec
Define whether a branch that connects to a sloped header is trimmed by adding more weld material or by trimming the branch end. For more information, see Define Port Alignments Per Spec.
Define Reinforcing Pad Widths
Define the minimum reinforcing pad width to use in branch reinforcement calculations based on the header and branch size and the acute angle of the intersection. For more information, see Define Reinforcing Pad Widths.
Define Reinforcing Weld Size
Define the minimum reinforcing weld size to use in branch reinforcement calculations based on the header and branch size and the acute angle of the intersection. For more information, see Define Reinforcing Weld Size.
Define Branch Selection Criteria
Specify the rules for selecting a branch short code based on the header and branch diameter and the angle of intersection. For more information, see Define Branch Selection Criteria.
Define Permissible Taps
Define the preferred tap and the list of permissible taps for the piping materials class. For more information, see Define Permissible Taps.
Define Default Change of Direction per Spec
Define the default change-of-direction boundaries for fittings. For more information, see Define Default Change of Direction per Spec.
Define Minimum Pipe Length Per Spec
Specify the minimum pipe length dimensions for a nominal pipe diameter in the piping materials class. For more information, see Define Minimum Pipe Length Per Spec.
Define Minimum Pipe Length Purchase per Spec
Specify the minimum pipe length and the preferred minimum pipe length for purchase based on the nominal pipe diameter in the piping materials class. For more information, see Define Minimum Pipe Length Purchase per Spec.
