As EN 13480 is a harmonised standard it's no surprise that the hydro test pressure is as per the PED (i.e. 1.43xPs or 1.25x(ftest/f)xPs). However, the piping I'm currently concerned with is SEP in the PED (<DN25) AND it's pressurised externally.
Where ASME B31.3 points to ASME VIII Div1 UG28...
I'm sure this will be a "no-brainer" to all you clever people out there, but I'm not up on my electropotentials and galvanic cells etc., so here goes:
Would using a combination of 70/30 Cu-Ni and 316L piping on a hydraulic power unit (water-glycol media) in a below decks marine environment...
