I have bought a couple of 12" WN flanges class 300 #RF and i have to drill them urgently. Suppliers in this period are closed for holyday, so I have to do it by myself. Can you tell me the distance between the bore axis (1/2") and the RF plan? Somewhere you read 0,94", elsewhere 1".
How should...
I'm compiling a piping specification for oxygen gas and liquid and I need to have some information about the type of pressure test usually used: pneumatic (with dry air) or hydraulic? And which precaution I need?
I will use 316 piping with 100% Rx
Thanks in advance

I'm defining a piping specification for oxygen gas and liquid and I need to know if and what kind of hand valves are used in oxygen service to control and regulate the flow rate e.g. globe valves or others.
Please, possibly let me know also some manufacturer.
Thanks in advance

I have a plain baffle type plates (shower deck) tower.
How can I estimate pressure drop of a gas flowing across the descending blade of water knowing the blade height?
Hallo,
in the piping specification i am working with I have GGG40 valves. I have found that the corresponding ASTM is A395. Is it true? And where can I find rating tables?
Thanks for your help

Question:
Which is the meaning of "nominal pressure stress (based on minimum pipe wall thickness ..." in ASME B31.3 Fig.323.2.2B (a)-(1)?
I have a ASTM A333 Gr.1 pipe at 15 barg (217,5 psig) and -46°C (-50.8°F). How can I calculate the stress ratio?
Thanks for your help
