Simon
Valve b1.Residueventing
The valve is operated both from the controlroom and engine room, see drawing below.

I wish I have checked this plate better yesterday :-[
 
I looked at is plate yesterday but did not notice this drawing of the valve :( It would had save me a couple hours of research trying to decide if the pipe went under or over Forward Diesel Exhaust Pipe.

I meant that only in terms of my drawing.

Simon
IXC piping
Again I don`t know the IXC very well but this kind of pipes looks like HPairpipes particulary where they enter the pressurehull. I believe the only pipe which could match in size would be the fuel testing pipe having intake from some 10 cm up from the tankbottom going all the way to the top but outside the pressurehull. I agree it sounds strange that the blowingpipes are going to the tankbottom, howewer the exhaustblowingpipes are doing the same. As to the mysterious box I have no idea.

Simon.
These plates are lockingplates generally used on essential nuts to prevent vibration etc unscrew the nuts.
Tore

Q. How do you know when you are going mad with detail?
 
 A. When you start adding locking plates to the pipe flange  ;D

Where did you find a pipe flange having 24 nuts in a VIIC Simon? ;D

It's the flange from the pressure hull opening for the exhaust.
 
I only have the one photo that showing my any part of this flange. From the photo I can not be 100% sure it has 24 nuts. So I base the number of nuts on the size of the flange, the size of the nuts and the spacing of the nuts that I can see from the photo.

I see, the end cover of the group exhaustvalve. I believe the cover has a coolingwater connection, may be double wall? and I am not sure the nuts are locked by lockingplates though ;D .

Simon.
 The flange towards the pressurehull have indeed bolts fixed with lockingplates. Interesting view angle. Working with the pipes on the group exhaust valve housing, hoping to be able to revert tomorrow my time.

From: C.B.  4318 REPORT ON "U-570" (H.M.S. "GRAPH")

H.P. Air Line

There are six groups of air bottles totalling twelve bottles.  Nos. 1, 2 and 6 groups are located externally in the casing, No. 3 in the E.R.A.'s mess, Nos. 4 and 5 groups in the torpedo compartment.  The bottles are charged by a Junkers diesel air compressor and a Krupp electric air compressor.

2.  The working pressure is 205 atms. and the air line is made of copper, external diameter 11/16 in., internal diameter 7/17 in.


Tore & Maciek, I imagine the copper was replace with steel, in the later war?

Added 3 new pressure hull openings.
  • High pressure air bank 2.
  • Muffler Exhaust Valve (Port & Starboard).
