Abstract

In case of fire occurring in an Oil and Gas facility, pressurized vessels may be exposed to fire. Though the entire system will be depressurized once a fire is detected, vessels may rupture, leading to risk of flammable, toxic or cryogenic fluid being released into atmosphere. Therefore, pressure vessels should be designed to withstand internal pressure without rupture during exposure to fire, at least until the system pressure can be decreased to a safe level. A pressure vessel rupture study should be conducted in addition to design code calculation in order to ensure a safe design in case of fire. As part of the recent trend for safer plant design, demand for pressure vessel rupture studies is growing and becoming a necessary requirement. In our previous presentation (PVP2015-45260 [1]), the material data for carbon steel (SA-516 Gr.70) and stainless steel (SA240 type304 and type304L) at high temperature range were obtained through material testing and were presented as our study result. And in the other presentation (PVP2016- 63184 [6]) that we've made, procedure for pressure vessel rupture study by FEM using the above mentioned material data was developed. For the present research, material testing in a dynamic condition wherein a more similar condition to an actual fire case were performed and comparison between the test results and FEM analysis was done. In conclusion, recommendation for the application of the pressure vessel rupture study was justified and necessity for further development of the above mentioned study was determined.
