Materials
Flanges
Flange materials values are sourced from the appropriate standard where available, or from sources such as ASME BPVC Part D 2019 Electronic Stress Table Y-1/Table 3 or from Total Materia database.
Gaskets
Gasket material properties are based on EN13555 gasket data as provided by the gasket manufacturer or published on Gasketdata.org. Generally, gasket properties at leakage rate L = 0.001 mg/(sm), internal test pressure of 40 bar and ambient temperature are used. If the manufacturer does not provide EN13555 gasket data, then published values by the manufacturer can be used if applicable. If there is no specific EN 13555 data or applicable gasket data, then default values as published in EN 1591-2:2008 are used.
Fasteners
Fastener materials values are sourced from the appropriate standard where available, or from sources such as ASME BPVC Part DM 2019 Electronic Stress Table Y-1 or Table 3 or from Total Materia database. Please note, when a specific standard does not provide a yield strength for a fastener material over a certain size, Calculate will set the yield strength at the last given value. We recommended that only new bolts certified to the specification are used in this scenario. Any new bolts shall meet all the projects requirements with regards to material strength, material compatibility, corrosion requirements etc.
Pressure Ratings
| Flange Standard | Data Source |
|---|---|
| ASME B16.5 | ASME B16.5-2020 Table A-1 for temperatures -29°C to 38 °C. |
| ASME B16.47 | ASME B16.47-2020 Table A-1 for temperatures -29°C to 38 °C. |
| JIS B2220 | JIS B 2220:2012 Table 11. |
| EEMUA 234 | EEMUA 234-2015 Appendix B |
Default Test Pressure in all cases is calculated as 1.5 times the maximum pressure as per above table.
