[MW:21298] Re-certifiscation of ASTM material to latest edition

Dear Friends,

I have below mentioned queries regarding Re-certification of ASTM Materials e.g. A36 Plate material to latest edition.

1. Can ASTM Material be re-certified to its latest edition same like we do in ASME Material? 
2. Can Manufacturer of ASME Stamp Holder Re-certify the ASTM Material?
3. Can Manufacturer Re-certify MTC's belonging to BS EN10204 3.1?


Waiting for your replies.

Regards

Shadab Alam

Re: [MW:21297] 316L WPS used for 304L.

Check if the A no is the same for 316 and 304. If yes you may use the same PQR assuming that the rest of essential and supplementary essential variables do not change

Re: [MW:21298] 316L WPS used for 304L.

Yes As it is in the same P No and F No catagory But you have to write the WPS addressing 304L base and E308L welding consumables  with supporting available PQR of 316L
(provided  you do not require to use this WPS for Impact requirement)

Dear all
As per my my knowledge ASME dont classify set in and set out type .
If your welder is groove weld qualified with required parameters and u r having valid wps you can weld anything.
All above asked requirements are come from European codes.
Experts pls correct me if I m wrong

Dear Rajesh,

Hope this will help.

The following interpretation of ASME Section IX applies to Set-through and Set-on nozzle installation:
Interpretation: IX-80-67
Subject: Section IX, Nozzle to Shell Connections
Date Issued: December 8, 1980
File: BC-80-675
Question: When nozzle or branch connections are attached to the wall or head of a pressure vessel, what are the basic criteria establishing procedure and performance qualification requirements, assuming impact test is not a requirement?

Reply: Where the nozzle is attached to the vessel by welding completely through the thickness of the vessel wall, the procedure shall be qualified for the thickness of the vessel wall penetrated by the nozzle or attachment. Where additional metal is placed on either the interior or exterior of the vessel wall in the form of fillet welds, they shall be considered as having been qualified by the procedure qualification covering the thickness of the vessel wall. Performance qualification for this weldment may be made in plate to cover the appropriate thickness of the vessel wall and the position in which the weld is being made. Diameter is not a factor.

Where the nozzle or attachment is welded to the vessel wall by welding through the thickness of the nozzle or attachment, the procedure qualification shall be made for the thickness of the nozzle or attachment wall at the time of welding. Performance qualification for this condition shall be made with the appropriate diameter pipe as required by QW-452.3, with the range of thickness of weld metal qualified determined by the thickness of the nozzle or attachment wall at the time of welding. Any fillet welds, both procedure and performance, will have been qualified when qualifying for the full penetration welds involved.

Note: The above interpretation refers to nozzle attachment to vessels, however the criteria apply to branch attachments topressure piping as well.

Re: [MW:21300] diferrence between E7018.. OK 55 & E7018.. OK 48

OK 48 is E 7018 and is with Mn up to 1.2% 
The impact strength is 80 J at  -40 C.  UTS  values are app. 540 N/sq.mm.
Works win DCEP, DCEN & AC 90 OCV.
 
OK 55 is E 7018-1 and is with Mn up to 1.5% 
The impact strength is 80 J at  -50 C.   UTS values are app. 590 N/sq.mm.
Works with only DCEP & AC 65 OCV t
U will get the values after a prolonged PWHT.

As U have seen, impact strength is higher in OK 55 and recommended 
where more impact is needed.

The baking temp. weld ability is same except that, u will  end up paying 
bit more for OK 55.There is no necessity to change to OK 55 when not needed.

Was there any difference in the weld quality if we  use one with E7018.. OK 55 and other with E7018.. OK 48..
Is there any  difference in temperature range for baking and holding  between the above two.. kindly share your information regarding this.

Re: [MW:21293] EN 10204 type 3.1 requirement

This type of requirement is generally raised by the client when they require minimum certification of the material from the manufacturer. Further, this requirement is generally mentioned when providing the Purchase order to the manufacturer and it is clearly state to mention EN10204 TYPE 3.1 on the MTC. 

If your PO to the manufacturer has included this requirement then definitely they should provide with MTC mentioning EN10204 TYPE 3.1 on it along with the manufacturer seal/stamp & signature to you.

Re: [MW:21292] QW-452.3 GROOVE-WELD DIAMETER LIMITS

Dear all
As per my my knowledge ASME dont classify set in and set out type .
If your welder is groove weld qualified with required parameters and u r having valid wps you can weld anything.
All above asked requirements are come from European codes.
Experts pls correct me if I m wrong
Cheers

Dear Rajesh,

The following interpretation of ASME Section IX applies to Set-through and Set-on nozzle installation:
Interpretation: IX-80-67
Subject: Section IX, Nozzle to Shell Connections
Date Issued: December 8, 1980
File: BC-80-675
Question: When nozzle or branch connections are attached to the wall or head of a pressure vessel, what are the basic criteria establishing procedure and performance qualification requirements, assuming impact test is not a requirement?

Reply: Where the nozzle is attached to the vessel by welding completely through the thickness of the vessel wall, the procedure shall be qualified for the thickness of the vessel wall penetrated by the nozzle or attachment. Where additional metal is placed on either the interior or exterior of the vessel wall in the form of fillet welds, they shall be considered as having been qualified by the procedure qualification covering the thickness of the vessel wall. Performance qualification for this weldment may be made in plate to cover the appropriate thickness of the vessel wall and the position in which the weld is being made. Diameter is not a factor.

Where the nozzle or attachment is welded to the vessel wall by welding through the thickness of the nozzle or attachment, the procedure qualification shall be made for the thickness of the nozzle or attachment wall at the time of welding. Performance qualification for this condition shall be made with the appropriate diameter pipe as required by QW-452.3, with the range of thickness of weld metal qualified determined by the thickness of the nozzle or attachment wall at the time of welding. Any fillet welds, both procedure and performance, will have been qualified when qualifying for the full penetration welds involved.

Note: The above interpretation refers to nozzle attachment to vessels, however the criteria apply to branch attachments topressure piping as well.

Re: [MW:21286] API 1104 Welders qualification renewal / restest ??

Dear

In my knowledge, As per API 1104 , the welders production becomes questionable, then need review on their qualification. So even after the 3 or 4 months their production is good , they can continue...with out requalification.


Thanks & Regards

if your welders are not working upto 6 month's then its required to requalify, otherwise as in your case welders can just proceed without requalifying unless specified by the client.

Dear Zakaria,

It depends upon your Client.If your client suggest you to do that, you can convince them or else provide them with the recent NDE reports if they are working in some other projects.

Dear Experts,

  We have one pipeline project according API 1104. Now with agreement
from us and client will stop all welding activities and restart after
03 or 04 months.

My request is: Will continue work with our welders but i don't know if
is it mandatory to retest, some renewal qualification ... I checked
API 1104 but nothing about this.

Regards.
