Stub-in reinforcing pad (MC=RPAD2) (SN=F180) TNF=P29A & None Plain/plain ends For GCP: Rating="-"; Sc/Th="-" For RCP: Rating="-"; Sc/Th="-" This model code represents a "stub-in" reinforcing pad; that is one in which the pipe terminates at the inside surface of the header. The following comments apply to all reinforcing pads: o Reinforcing pads are defined in the piping materials classes to have an actual value for fabrication category, which may be changed after placement. In the isometric drawings, a note will not be placed in the graphic part of the drawing to show their size. A short description has been prepared for reinforcing pads and is displayed in the bill of materials. o Reinforcing pads may be placed with either single or double curvature, for example reinforcing a pipe or a head respectively. o The angle of intersection between the header and the branch is part of the table name containing dimensional parameters for the component. This angle will be derived by the system from data in the design file. Four different types of intersection is recognized: - Intersections at angles equal to or greater than 20 but less than 45 degrees: the number "2045" is used as part of the table name. - Intersections at 45 degrees: the number "45" is used as part of the table name. - Intersections at angles greater than 45 but lesser than 90 degrees: the number "4590" is used as part of the table name. - Intersections at 90 degrees: the number "90" is used as part of the table name. o Two possibilities exist regarding dimensions for a reinforcing pad: - If a "0" is entered in the "MOD" column of the Piping Job Specification, dimensions are to be derived from either a data table and/or from branch calculations. For the case where no branch calculation is involved, both the pad width and pad thickness are included in the applicable dimension table. If a branch calculation is involved, a value is provided in the dimension table for pad width and either a "-" or value for pad thickness. See section titled "Choosing a Branch Connection from a Branches Table" for details. - If a "1" is entered in such column, the system is to prompt for dimensions. If dimensions are provided by the user, their values are stored in the TDB so that in subsequent recreations of the piping system, those values and not those that might exist in a data table are used by the system. o Data defined for these components will allow the system to determine the applicable stress intensification factors (SIF) to be used in stress analysis of the piping system. o The thickness of the portion of piping from PCP2 of this component to the centerline of the header is reported as "RIGID" to the Pipe Stress Analysis software, regardless of the value in the Piping Job Specification so as not to provide a fictitious flexibility. o The empty weight of these components is neglected.查看更多6个回答 . 3人已关注
