Piping stress isometrics
A class with identifier http://rds.posccaesar.org/ontology/plm/rdl/PCA_100006378
| Source ontology | norsok-z001 |
| Comment | Piping stress isometrics shall include the following information:
- Line number;
- Process data (temp. and pressure);
- Valve weights;
- Equipment nozzle loads;
- Stress summary;
- Reference to P&ID;
- Restraint loading and displacement;
- Spring summary;
- Calculation No.;
- Separate document no with revision code on each stress iso (not stress report number);
- Special supports, typical: gap, adjustable, PTFE;
- Equipment nozzle with tag no;
- Pipe specification break;
- Reference to adjacent isometric drawings;
- Special items;
- Penetrations;
- Pipe stress report no;
- Dimensioned pipe support locations and support numbers including spring supports, etc.;
- Node numbers from calculation model (as a minimum for each pipe support, valve, equipment nozzle, interface to other lines/sheets/isometrics and location for max utilisation).
- Support function NOTE: For equipment packages where the amount and size of piping is moderate, or the piping might be mostly for support functions (cooling, lubrication, drain etc.), piping stress isometrics from the manufacturer are not necessary. For large packages with a considerable amount of larger piping, piping stress isometrics for the main piping should be delivered. Selection should be done early in the project. |
| NORSOK Z-001 rationale | Piping stress isometrics shall be provided for all lines for which stress calculations or evaluation have been made. |
