a piping assessment for the use of a union joint? a piping
assessment will eat a lot a resources at the plant - my take is to
utilize it where its really needed and normally we go thru the
motion of performing an assessment if theres a hazard that is
involved or the risk is high or if a mitigation is required.
We're using the word "assessment" here as it applies to piping same
as the API.
