It sure helps, thank you.

I still haven’t found the type of this flange but it puts me in the right direction. It is now clear to me that this must be a kind of compact flange.

“On block valves”!??

Not on block valves…I never mentioned block valves.
They pipelines are connected to valve blocks. I mean (connection-) blocks where valves/servos etc are mounted to. It is partly visible on one of the photos.
This is very common in the hydraulic industry.

I’ve never encountered these “types” of flanges before

Neither have I.
Normally we use 3000/6000 psi square or SAE flanges (AVIT and/or STAUFF make) in the hydraulic industry but I’ve never seen these before.

…with a “normal” type of flange

Define “normal”. You mean “normal” DIN or ASME flanges? That’s very uncommon in the hydraulic industry.

They are located on the valve blocks, in the pipeline and on the cilinders. It’s a (250 Bar) hydraulic system of a press located in Belgium, possibly delivered by a (American) vendor. The customer does not have any information of it.

That’s totally clear. Thanks!

What is an Re Value?

Re = Yield strength

[quote]Hello everybody,

I have a question for you]

Take a look at the calculation methods of (for example) British Standard BS5500, section 3 or DIN standard 2505 or EN 1591-1. Al three standards are describing a (more or less….) simple method to calculate flanges.
Bolts can be calculated using the VDI 2230 calculation method.
