To check that the component as described does what you require, make a partial retrieval between its model and the system s. Check for conformance of the API specs to your requirements. 

American Petroleum Institute (API) has developed standards for testing downhole cements that are described in API recommended practice 10 [3]. In API specifications (API Spec. 10), if one assumes an ambient temperature of 80 °F (25°C), then the depth dependence of the downhole temperature is approximately given by... 

Ideal Temperature and Pressure Profiles in Oil Wells used in API Spec. 10 [3]. 

The permeability of the set sealant is measured by an API-recommended permeameter, which consists of a cylindrical sealant holder that is filled with the setting slurry. Once the slurry has set, the holder is fitted on a base. The base has an opening for gas connection, which can be attached to a nitrogen gas cylinder. Gas at different pressures is applied, and the pressure difference is measured by a mercury column. Knowing the pressure difference, the cross sectional area of the holder, and its length, one calculates the permeability in millidarcies. Details of such a permeameter and the procedure may be found in the API Spec. [3].

Ring type joints are generally considered only for a maximum of 4500 PSI. However API Spec 6A flanges have standard sizes for RTJ flanges to 20,000 PSI service.
