Analysis of the loads following several standards for nozzles at a pumps and vessels which are part of the ROHR2 project. The nozzle analysis is carried out by the module ROHR2press. ROHR2nozzle is part of the ROHR2 standard package.
Currently the following standards are part of the nozzle analysis:
- API 610
- API 617
- API 661
- DIN ISO 9905
- NEMA SM23
- Nozzle Spec
- EN ISO 5199
- DIN EN ISO 10437
- DIN EN ISO 10440
- DIN EN ISO 13709
- Allowable loads acc. to manual input in ROHR2
The first step is the definition of nozzle analyses in ROHR2 and the selection of a standard.
Depending on the standard one or more nozzles in the ROHR2 model may be assigned.
A sub-type can be selected according to the standard, too.
The subtypes are defined in the standards.
Depending on the selected standard additional input may be required.
Calculated loads are transferred from the ROHR2 calculation. The allowable stresses are determined depending on the standard.
The stress utilization will be analyzed and documented
In addition the nozzle analyses may be carried out independent of the ROHR2 model.
In this case the maximum occurring loads need to be inserted manually.
A documentation in *.rtf format is generated for all calculated components. The document is shown in the associated text processor.
If ROHR2nozzle has been started inside a ROHR2 project the output can be made part of the ROHR2 report.
