Axiomatization Decision LogRegistro de Decisões
1 Identity-Giving FunctionFunção Identitária
Function class
PressureContainmentFunction ⊑ ContainmentFunction
Realized in
PressureContainmentProcess ⊑ PlannedProcess
The identity-giving function is the designed capability to safely contain fluids or gases under internal and/or external pressure. This specializes the broader ContainmentFunction by adding the pressure-bearing requirement.
2 Genus DeterminationDeterminação do Gênero
Vesselbfo:Object (BFO_0000030)
From parent candidates, 'Static Equipment' is too broad. The most specific appropriate superclass is 'Vessel', which is already enriched in the ontology with ContainmentFunction. Pressure vessel is a specialized vessel designed for pressure service.
3 Differentia SpecificaDiferença Específica
∃bearerOf.PressureContainmentFunction

A pressure vessel is distinguished from other vessels by being designed to withstand significant internal and/or external pressure loads.

The differentia is the specialized pressure-bearing capability that goes beyond basic containment. This requires pressure-rated design, materials, and construction standards.
4 Necessary PartsPartes Necessárias

No necessary parts recorded.

These parts are universal requirements for pressure containment capability - a pressure-rated shell provides the containment boundary, and pressure-rated nozzles provide controlled access.

TransformationTransformação
pressure containment with no chemical transformation
Pressure vessels contain pressurized fluids (liquid, gas, or multiphase) maintaining pressure integrity without altering the fluid composition. Input/output count varies based on vessel design and service.
