Liquid PSV Sizing

Liquid PSV Sizing

Liquid PSV Sizing

(OP)
In API 520-I, two sizing methods are considered in sizing for liquid relief. They are:
1) Section 3.8 - Sizing for Liquid Relief: Pressure Relief Valves Requiring Capacity Certification.
2) Section 3.9 - Sizing for Liquid Relief: Pressure Relief Valves Not Requiring Capacity Certification.

I need to understand the differences between the two methods.

From the two methods, which one can I use to size the PSV to be installed on a crude oil pipeline.

Thanks for your anticipated comments.

Certified.

If it ain't broke, don't fix it. If it's not safe ... make it that way.

BigInch,
I do not understand what you meant by certified? [bigsmile]

Go for the capacity certified option.

If it ain't broke, don't fix it. If it's not safe ... make it that way.
