[MW:1487] FW: 1485] HYDRO TEST OF VESSELS

Rushabh,

I forgot to reply your below concern,

Change in vessel length doesn't affect the HOLD time.

Rushabh,

UG-99 of VIII-1 does not specify a minimum hold time for hydrostatic
test pressure. It all depends on the time needed to fully inspect the
vessel to ensure no leaks are present.
You have to also check the client specifications; they often specify
minimum hydrotest duration. For vessels I recommend 1 hour stabilization
at maximum pressure.

Does ASME define the HOLD time required for holding pressure during
HYDROTESTING of vessels?

If yes does change in vessel length affect the HOLD time?

Hello Muhammed,
 
In response to your question below, X-ray radiography is you best choice due to quality issues. 
 
The second question is slightly difficult to answer as each tube/generator has different characteristics, as also the film and geometric variables have.  In referencing one of my resources, a higher end X-ray tube rated at 400-450 kV could theoretically penetrate thickness up to roughly 300 mm.  The lower limit for 50 kV is approximately 20 mm.
 
I usually work with castings from 30 mm to approximately 75 mm, although, I primarily use digital radiography using a CMOS detector. 
 
A generally accepted method of ensuring acceptability of a method is to demonstrate required sensitivity (i.e. hole-type or wire-type image quality indicators) per referencing code. 
 
I have a colleague that is better accquainted with thinner materials.  I will forward him your question and I will email you if I can clarify practical limits.

Thank you,

Charles Nelson

Hi friends,
 
Good morning,
 
I have a query regarding the radiography of aluminium.
 
X-ray or gamma ray is better for aluminium?
 
If x ray is better , what is the thickness range it can be done?
 
If gamma ray is better , what is the thickness range it can be done?
 
If anybody having the procedure, please forward

Hello Muhammed,
 
In response to your question below, X-ray radiography is you best choice due to quality issues. 
 
The second question is slightly difficult to answer as each tube/generator has different characteristics, as also the film and geometric variables have.  In referencing one of my resources, a higher end X-ray tube rated at 400-450 kV could theoretically penetrate thickness up to roughly 300 mm.  The lower limit for 50 kV is approximately 20 mm.
 
I usually work with castings from 30 mm to approximately 75 mm, although, I primarily use digital radiography using a CMOS detector. 
 
A generally accepted method of ensuring acceptability of a method is to demonstrate required sensitivity (i.e. hole-type or wire-type image quality indicators) per referencing code. 
 
I have a colleague that is better accquainted with thinner materials.  I will forward him your question and I will email you if I can clarify practical limits.

Thank you,

Charles Nelson

[MW:1467] RE: 1462] Flange dimensions for size above 12" rating 2500#

Dear Vinayak,
The requirement sought by you for the desired size does
not come regularly for Piping in process industry.
To be precise this requirement does occur in the design of Vessel or
equipment Flanges or High pressure piping in Power Plants. There the
standard referred is ASME Sec VIII div 1 as suggested by Mr. Somesh. I can
remember the well known Workshop in Hazira, and they had designed similar
Flanges for VGU Reactor of a known refiner, and provided the companion
flange for the same.
You may seek the information based on this issue on different Blogs
available for Pressure Vessel group, similar to this one.


I saw the catalogue attached by Mr. Bathula, But afraid to say it that the
dimension is again not as per standards.
So I would suggest you to get a vendor who has previously worked for these
ranges of Flanges, and you may get the detailed information based on that!
Please don't be afraid to share the desired information of your result.
It may be helpful for anyone who is related to this industry.

When  "100 % RT" OR "Full RT" is specified in data sheet, is it require to perform the radiography of category D joints (nozzle to shell joint) ?

Yes.. I agree with the below answer..
 
To add it further..
 
Let us consider a cylinder on a vessel for a certain length and it has 4 Cir. Seams and 4 Long. seams.
 
If the vessel calls for FULL radiography, then a spot ( i repeat a spot, means not Spot radiography, it is aportion, say 100 to 200mm ) on all the 4 cir seams, 4 long. seams have to be radiographed and all the T joints have to be Radiographed.
 
If the vessel calls for 100% radiography, then the entire length of the Butt joint welds have to be radiographed (thro full length).

Re: [Pressure Vessel] Radiography Test : FULL Vs 100%
 
Dear Bathula,
 
Actually ASME VIII-1 also specify the term of 100% radiography.
I found this wording some in ASME, for example:
<AA> Part UW Reqr't for PV Fabri'd by Weldings
UW-52, see at the last sentence of note.
100% RT shall be applied while the previous spot result radiographically disclosed welds defects must be eliminated.
<BB> Part ULW,
See section ULT-57 Examination, all butt joints shall be examined by 100% radiography (for me it means UW-11) except as permitted by UW-11 (a) (7) (for me that means UT instead of Full or 100% RT).
 
Re to your response, it look like both of "100% RT" and "Full RT" have a different meaning.
If yes, then I believe, ASME should specify the detail terminology of 100% RT at least at the same way of this code specified Full RT at section UW-11.
Unfortunaltely so far I can't find it. (That what i'm asking for in my query mail below).
Refer to the above references, in my humble opinion this 100% RT should be the same meaning of Full RT.
 
However thank for your response and please have futher discussion if don't mind.

 Does "Full RT" and "100% RT" has the same meaning of Radiography Test?
If NOT - which section of ASME Sect. VIII Div.1 (or 2 or 3) that describe in detail description for both "Full RT" and "100% RT"?

[MW:1455] Re: 1453] Re: Radiography Test : FULL Vs 100%


Dear Raghuram,

I think Fig UW 40 (f)-(1) specified below shall be UW 16 (f-1) to (f-4).

When nozzle connection is as per UW 16(f-1) to (f-4), it is "Category D butt joint". In other cases it is "Category D corner joint".

Please refer UW-11(a)(5) and joint efficiency table UW-12 (type no 1 & 2 joints) for radiography of category D butt joint. When full radiography is specified for the vessel and if category D joint is butt weld type, it requires full radiography. If category D joint is corner joint, it does not require radiography. Please refer joint type no 7 & note 5 of table UW-12 for category D corner joint.

Regards,

Santosh

No, unless specifically asked for or using the joint type shown in fig UW 40 (f)-(i),
But I have Q? here, is it still considered as category D if one uses the weld joints shown in fig UW 40 (f)-(i)?
