in the Re-tube process of a fixed tubesheet. Id like to validate my understanding of the process.
Is it as below
1. Grind out welds on all tubes
2. Pull all tubes out.
3. re-detail (tube sheet)
4. insert new tube sheet
5. reweld up tube sheet.

Id like to validate that its only a convention in the UK that electrical cables are black and red above a certain voltage etc..
from what i can tell its what is normally done .. not a standard otherwise this is only cable colour you would normally get
Please delete if not ok to ask:
All the literature I can see (and the info ) from valve vendors (Ive found so far).. is that rugosity of GMP valves is always 0.8 or less.
A chemist in our organization has asked can we get lower , say 0.5 . We have some drivers for a lower spec for quality...
Hi,
Sorry if this basic questions and not approprate please delete..(sorry)
I am a project engineer without an EI background. but a moderate experience with this..
I'm looking to get a background basic understanding of capacities and system setup.
Why I am asking:

For piping design of GMP systems is there an EU / British standard which must be followed.
The current systems on a unit we have is clamp ring. Is there an EU standard or reference which dictates this.
thanks
Im not sure exactly where to post this.
I'm supporting a GMP plant. I after a design guide for general GMP practice..
is it a GMP requirement to have flooring plate ? (on 1st,2nd. 3rd floors..)
or is the requirement just to be clean.. and generally structural steel floors are plated to...
(None electrical engineer question here. so applogies)

Dear all,
i like to confirm my understanding of the limit for balanced bellows relief valves.. can you get a valve with a set pressure and balanced bellows below 1 barg?
i Dont believe so but i wanted to check
thanks in advance
Apologies if this has been asked before for different levels of voltage is Medium 415 V, 11KV etc.. is there a minimum separation distance from mult-mode fibre optic cable?
or a design code which should be followed to design too. For a mixture of overheads cable racks and ducted cable runs...
Hi,
I'm after some short advice here or a decent rule of thumb calculator to approximate the potential to cool about 1.5 te/hr in 1 inch pipe from around 200 to 60 C in finned pipe.
Its a basic oil fluid.
From a quick google search typical HTC id assume would be 500 w/m2 K, but I need a...
