This post was last edited by ningjingwei on 2016-6-12 at 14:19. May I ask, when a safety valve discharges to a cold flare, is it necessary to insulate the inlet and outlet of the safety valve? Why?

Insulated for import, not required for export. Exporting means emissions, so insulation is pointless.

Then why does importing require cold preservation?:)

Mm-hmm, I get it. Does that exit require PP?

It’s not necessary; if you think there might be danger in practice, you can add protection.
