So, you think you know what load case combinations to use for your ASME Section VIII, Division 2, Part 5 analysis to satisfy Protection Against? Common sense says to follow to Code rules in Table 5.3 – but do you fully understand what that means? And, what loads should you use to satisfy Protection […]
Process vessels such as towers, drums and heat exchangers may be exposed to low temperatures as a part of normal operation or as the result of an upset condition. Carbon and low alloy steels typically used in process vessels undergo a transition from ductile to brittle behavior as temperature is reduced and are at increased […]
While there are currently no explicit rules on how to perform a finite element analysis (FEA) if you are doing so in support of an ASME Section VIII, Division 1 vessel, there is good practice. Regarding rules, all you have is from Article U-2(g), which says: This Division of Section VIII does not contain […]
While fracture mechanics is used in fitness-for-service, FFS, for evaluation of crack like flaws that are detected and for evaluation of the potential for brittle fracture, it is also used in new design to evaluate fatigue life. The rules for high pressure vessels in Section VIII, Div 3 and ASME B31.3 Chapter X permit and […]
The pressure vessel and piping jurisdiction in Alberta, Canada is ABSA – the pressure equipment safety authority. All pressure equipment as defined by the provincial Safety Codes Act must be registered with ABSA. I have been involved in registering piping systems and pressure vessels in this, my home jurisdiction. The focus of this blog […]
