RE: [MW:20713] ASME SEC IX QW202.1

Attached is a copy of 2013 ScIX QW-202.1.  The following is my interpretation of the requirements.

 

Three conditions are set up in the case of a specimen failure:

 

1)     (2nd paragraph) Failure was caused by something unrelated to the welding conditions.  This could be a failure of the grips, a nick in the specimen, an error in machining, power failure during the test, etc.  In this case one for one replacement of the specimen from the original PQR coupon or a new test coupon welded with the same parameters/conditions may be made and the additional specimen tested.

 

2)    (4th paragraph) If the failure was caused by a problem that requires a change in essential or supplementary essential variables to correct the problem, then a new PQR test plate must be welded and all tests repeated.  Personally, I don’t see how the original PQR test(s) would be valid if the essential (or supplementary essential) variables have changed. 

 

3)    (5th paragraph) If the failure was caused by a problem related to welding but that requires a change not affecting the original essential or supplementary essential variables, then a new coupon can be welded and the failed test repeated.  The changes made to the non-essential variables or other parameters to obtain the acceptable test(s) must be addressed on the WPS.  In this case it is one for one replacement. 

 

Typically a failure of a PQR test will be the result of condition 2) above.  In my experience, use of condition 3) is rare. 

 

Just my opinion along with a strong belief that a short cut isn’t necessarily the quickest route to anywhere.  Good luck.

Subject: [MW:20697] Tube to  tubesheet joint with projection per QW 288
Sent by: materials-welding@googlegroups.com




In fabrication drawing, Tube to  tubesheet joint with 4mm projection.
in the Mock-up/PQR, vendor kept 0.5mm projection, but fused the tube with the tubesheet.


Is vendor to provide mock-up with 4mm projection, or change only the WPS to show 4mm projection in the joint, with the same PQR.


as per QW 288 this is not an essential variable, hence in my opinion revision of WPS is OK.

I disagree
Please read carefully: It is written in the 1st paragraph of QW 202.1 "If any test specimen required by QW-451 fails to meet the applicable acceptance criteria, the test coupon shall be considered as failed"

    Thanks for the info,

    Please note that QW202.1 also allows for retesting ( after considering all ifs & buts in the code/ QW153) from the same test coupon. Now my question is, if one tensile specimen fails, how many additional test specimens shall be tested.

    Dear friend,

    If any specimen fails to meet the requirements, the test coupon consider to be failed and a new test coupon shall prepare. (It could be with the same parameters or changed parameters)

They do not meet the requirements of B16.5 as far as the dimensions are concerned. They may not meet also the temperature / pressure ratting since the cladding process may alter the flange properties.
The dimensional issue is not a problem. The manufacturer has to provide evidence that the cladding process has not altered the temperature/pressure ratting

Dear Experts,

We have fabricated one vessel as per ASME Section VIII Div. 2 Edition 2010, Add. 2011. The vessel is internally cladded with Alloy 625 for corrosion resistance purpose. Cladding thickness is not considered in the design. The flanges were ordered as flat face and corrosion resistance overlay was applied, and machined to RF required dimensions as per ASME B 16.5. Reference to the attached interpretation, when the RF was made with different material (corrosion resistance cladding), does these flanges are categorized as non standard flanges?? Please give your opinion on the same.

Regards,

Josnit

Dear mok
there is no straight mention to ovality as per B31.3 and the only presence to diameter tolerance is the next snapshot (332.2 bending)
and i think it can works
