Re: [MW:29441] PQR & WPS thickness limits

As you said ,Test coupon is 50mm thick with GTAW 25mm and SMAW 25mm welding. Generally GTAW is used for root and hot pass, not for 25 mm. If you do 25 mm GTAW WELDING, your production rate as well as welding cost will be more.

Follow ASME Sec IX QW-451.1, It will be helpful for you

I have reviewed a PQR for GTAW+SMAW welding. Test coupon is 50mm thick with GTAW 25mm and SMAW 25mm welding. On the WPS thickness range is given as upto 200mm for both GTAW and SMAW.
How is this possible as more than 38mm test coupon qualifies for up to 200mm welding ??

Re: [MW:29441] Re: ASME SEC IX Code Issue

Inter pass Temp. is not the essential variable and as I know there is no such criteria for Max. and minimum inter pass temp. limit. If your test coupon pass required DT ( Tensile Test, Face Bend, Root Bend) , there is no problem

[MW:29441] [Urgent] Tube to Tubesheet Calculation

Hi,

I am new to this topic. I have to solve the engineering part of doing the calculation.

Here is the statement of problem-->

Take the actual nominate tube and tube sheet material, conduct analysis
mathematically to estimate the joint strength.
 Conduct analysis to estimate the maximum expansion the tube can take
without affecting the integrity of the tube section. (Check the wall thickness
reduction in %)
 Once the maximum expansion on tube has been calculated, check the tube
to tube-sheet joint:
 0.25mm oversized hole with the tube at maximum expansion
 0.5mm oversized hole with the tube at maximum expansion
 0.75mm oversized hole with the tube at maximum expansion

Nominal tube diameter-38.1 mm
> Nominal tube sheet hole-38.56 mm

tube thickness 3.2 mm

Tube material SS 304

TEMA Extract (values in mm, bracket in inches

38.10 (11/2) Tube nominal dia

38.56 tube sheet nominal dia
(1.518)
0.18 under tolerance
0.08 over tolerance
(0.003)

I have calculated maximum expansion of the tube as per the attached excel. Can someone help me to make the calculation for the above statement?

Thanks

Re: [MW:29441] PQR & WPS thickness limits

Pl ref QW 451 for base metal and weld metal. Hope that u agree with base metal thickness ( T) range. For weld metal (t) thickness range is as follows, if deposited weld metal thickness is less than 19mm, then range is 2t. And deposited weld metal equal or greater than 19mm, then thickness range is 200mm. Thanks

Re: [MW:29430] Re: Multipass - Heat Input

I would advise to read QW-409.1 and the appendix H in ASME IX.

When impact test is applicable, heat input becomes a supplementary essential variable.

New PQR is required when heat input is increased.

So, considering the calculations of heat input given in QW 409.1 you have to record the max heat input per pass

Re: [MW:29430] Heat Treatment : Dish End

Wrong,

you should read UCS-79 carefully. The HT is a function of P-No and extreme fiber elongation, and service conditions.

UCS is applicable for carbon steel materials

For high alloy (example stainless steel) pls refer to UHA-44

For enhanced ferritic steels pls read UHT-79.

Friendly advise: read the Code carefully

[MW:29427] Re: Multipass - Heat Input

I.e Heat Input is different in various layers for the fillup passes.

Hi ,
A very good evening to you all.
My doubt is in establishing the heat input for multipass welding , (root , fill & cap) , for the fillup passes my parameters are different for different layers , which one should i consider for establishing the Heat Input because in this CVN Requirement apply & the heat input cannot be increased as per the code (Be it ASME Sec IX or AWS D1.1).
How to solve this problem? Kindly help.

Regards,
Gowtham.

Re: [MW:29426] Re: ASME SEC IX Code Issue

Except ASME B31.1 and B31.3, all other Sec1, VIII only non mandatory requirements on Preheat. There are exemption to PWHT if we do Preheat with certain limitations.

It is not necessarily the information you are looking for, but I think it can be a guide for you to resolve your doubt, I recommend that you see the NONMANDATORY APPENDIX R PREHEATING of Section VIII Div. 1 of ASME, it brings excellent recommendations, but it is not a guarantee.
Regards!.

The code does not give you these temperatures.
That's the welding engineer's job. Of course, there are tables and recommendations but not in ASME Sec. IX.
These are "change" in temp, not the temperature itself.

Dear All,

Design Code: ASME B31.3    Welding Code: ASME SEC IX

I have a Low temperature carbon steel impact tested PQR with a PWHT range of 600⁰±10⁰C.Is this condition giving an exemption for me on QW406.3 to prepare a WPS with maximum interpass temperature of 200⁰C.

Maximum interpass temperature observed during specimen welding: 140⁰C

[MW:29425] PQR & WPS thickness limits

I have reviewed a PQR for GTAW+SMAW welding. Test coupon is 50mm thick with GTAW 25mm and SMAW 25mm welding. On the WPS thickness range is given as upto 200mm for both GTAW and SMAW.

How is this possible as more than 38mm test coupon qualifies for up to 200mm welding ??

Re: RE: [MW:29423] PMI Testing -ss316

SAES-A-206

10 Acceptance Criteria

10.1 For acceptance, it must be demonstrated that materials contain the amounts of alloying elements shown in the material specification. Alloys shall be acceptable if the alloying elements are each within 10% of the specified range of values.

10.2 Welds with consumables that match, or nearly match, the base metal composition shall be within ±12.5% of the ranges allowed in ASME SEC IIC for each element.

11 Rejection Procedures

11.1 If the PMI testing results fall outside the acceptable range using a method described in Section 8, the Equipment Manufacturer or the Fabricator, as applicable, has the option to conduct a more accurate analysis at his own expense to determine the component acceptance such as obtaining a chemical analysis performed by an independent testing laboratory. The alternative test method or independent laboratory must be acceptable. The results of the more accurate test method or independent chemical analysis shall govern.

11.2 If any component or weld is found unacceptable, it shall be replaced and the replacement shall be alloy verified in accordance with this standard.

Hi,
Please see the highlighted text. It does not say what technique was adopted. PMI could be done by XRF and OES techniques. Assuming this was done by XRF, this technique could yield erratic results. More number of spots/reading, better is the accuracy. How many spots were taken?
If would be advisable to test the sample with both XRF and OES and then come to conclusions
Also see below the recommendations from API-578 and act accordingly.
Thanks.

7 Evaluation of Testing Results
7.1 Material Acceptance Methods
The owner/user may elect any one of the following methods of material acceptance.
a) Materials can be confirmed to contain the nominal amounts of alloying elements specified in the relevant
materials specification (e.g. ASME Section II or ASTM specifications).
b) Materials can be classified through a qualitative sorting technique (see 6.7) to establish the conformance
with the intended material.
c) When PMI indicates that alloying elements are outside the ranges indicated in the material specification,
the owner/user may still choose to allow the use of the tested materials in situations where a person
knowledgeable of the appropriate damage mechanisms confirms that the material will perform
satisfactorily in the service.
d) If testing using one of the portable or qualitative analysis methods leads to the potential rejection of a
component, a more accurate analysis may be used to determine component acceptance (see
Section 6).
