How to fill in the "Rel. Temp." column of the PRESSURE RELIEF VALVES Spec. form of ISA S20?

Could anyone explain me the reasons for using RB valves on a pipeline and on which type of pipelines? I know only as the cost and should not be used on a pigable pipeline.

Does anyone have experience at applying for a CRN (Canadian Registration Number) for Cat C valves that are B16.34 design but are made from a material that is not listed in B16.34?

I would like to draw your attention on the EN 1779 standard (dated August 1999, as far as I know) about Non-destructive testing - Leak testing - Criteria for method and technique selection.

We're using a 1.5" peristaltic pump to empty a vertical container in a smooth and stable rate (around 30L/min). What we noticed is a repeatable distortion in the flow rate caused by the peristaltic tu
