PN Flange test pressure
PN Flange test pressure
(OP)
Can anyone tell if the maximum test pressure is stated in the latest standard for PN designated flanges (BS EN1092-1 2007) Previous std (BS 4504) stated 1.5 x nominal pressure rating.
I cannot find any reference to maximum hydrotest pressure in the latest standard.

RE: PN Flange test pressure
- Nominal design stress:
at operation 140 MPa;
at assembly and testing 200 MPa (Ptest=1.43×PN)
Hope this helps.

acc. PED it's 1.43xPN
So that's 2-2.

So, it's 3-2...just not sure who's leading.

"D'OH!"
Of course, I *meant* 1.5 x flange rating, not MOP.
