Dear all,

We have a situation that we need to weld cap (material P11) to weldolet with P22 material. Size 2" NPS. Line temp is 560C and pressure 48bar. The rating of the main header is 1500# P22 mtl. Can we weld to the following conditions P11 mtl cap to weldolet P22 mtl.

Re: [MW:29766] WPS by ASME and WPQT by Indian Standard

Hi,

None can be entertained whether he is client or owner with reference / evidences.

So what was your contractual agreement, any written documents by both parties on following standards international / clients manual cut off what to be followed?

Its all depend upon writings, what has written to be followed, if you are right and still client is insisting you for non mandatorial requirement highlight to your upper management.

Re: [MW:29766] A335 P11 can be used instead of P22

Hi, 

If header pipe is P5A why it is connected with P4 CAP (Tie-in point)? in which P5A weldolet to be fused with P4 CAP? is that your query? 

Is this pre approved design or shortage of material? so you just inserting one what you have?

write a TQ to ''the company'' take approval with disimilar WPS.

I hope there shall not be an issue if you are proposing with your adjustment in case, but designers approval is final.

Re: [MW:29766] ASME B31.3 2016 Ed - PWHT table

As per ASME B31.3 2016 when preheat of 95 Deg C for greater than 25 mm thk, PWHT is not mandatory.

ASME B313.3 does not ask to perform PWHT if above mentioned conditions are fulfilled.  How ever there are client specifications and if the design is as per the previous Editions of B31.3 PWHT may need to be performed.  This will have to be decided in discussion with client.

Re: Re: [MW:29764] Re: ASME B31.3 2016 Ed - PWHT table

Hi,

On first condition, you have to check with your Designer, they may not not approve exemptions, your owner or company, basically some strignet world class ''COMPANY'' does not entertain most of the international code exemptions as per service requirements irrelavant of thickness or irrelavant of exemptions.

Secondly, note 6 of T 331.1.3 says if single layers or single pass on productions, same shall be written on  WPS with HI check ±10%.

Concluding that you may waive with CODE exemptions if you exempt the above conditions.

[MW:29762] Usage of SS304 tubes ot SS316L tubes in cooling water exchangers

Recently I observed that in one of the cooling water exchanger (tube in tube) which has Hydrogen at 230DegC on the outer tube and cooling water on the inner tube. The tube metallurgy was SS304. 
Where as in another unit, a cooling water exchanger with SS 316L tubes had lean amine on shell side. 

On what basis is 316L tubes chosen over 304  tubes when a cooling water exchanger is designed?

 - I have two things in mind as far as corrosion is concerned, one being ClSCC and another being PTASCC.

As per AWS D1.1

But In WPS thickness mentioned 28MM ( 3.2mm to unlimited )

 

As per AWS D1.1 Table   4.2

For thickness range is qualified for 25 mm ( 3mm to 2T) if i am correct.


2)   Regarding Position – PQR is qualified with 2G( Horizontal)

But in WPS welding Progression – Uphill. whether 2G can weld Uphill position.

Dear all,

We have a situation that we need to weld cap (material P11) to weldolet with P22 material. Size 2" NPS. Line temp is 560C and pressure 48bar. The rating of the main header is 1500# P22 mtl. Can we weld to the following conditions P11 mtl cap to weldolet P22 mtl.

RE: [MW:29758] As per Section IX Thickness range qualification

WPS thickness qualification  is determined using Table QW-451.1 – see below

 

Your base metal thickness, 17.48mm, falls in the third grouping "Over 3/8 (10mm) but less than ¾ (19mm).  Per this line, the qualified base metal thickness is 3/16 (5mm) to 2T (twice the test coupon thickness).  Further, the maximum qualified weld metal thickness is 2t (twice the deposited weld metal thickness) – this is determined solely from each essential variable grouping, your case per process employed.  This latter is typical.

So, for your WPS the ranges of qualification per Table QW451.1 are:

 

Base metal:  5mm to 34.96mm (inclusive)

GTAW weld deposit:  16mm maximum

SMAW weld deposit:  18.96mm maximum

 

You can, of course, limit your ranges of qualification to less than the Table QW-451.1 permitted ranges but cannot exceed them without additional qualification.  So, yes, you can choose to restrict base metal thickness range to 13.1mm to 26.2mm since it is within the maximum permissible range.  Likewise, you can also  restrict the maximum deposit thickness to 14mm for GTAW and 18.5mm for SMAW since they are less than the maximums of 16mm and 18.96 respectively.

 

Note:  if impact qualification is required, additional restrictions apply.

 

Enjoy!

Dear Experts,

 

I have some difficulty to interpret the requirements of ASME section IX

 

I have a  PQR Based on a dual process GTAW+SMAW ( 8 mm+9.48 mm) on an 17.48 mm ( 24" NPS ) butt weld.

 

If i am use this PQR what would be my thickness range in WPS  a) Weld metal thickness range for GTAW + SMAW ? b) And what is the base metal thickness range ?

 

If i set in WPS base metal thickness 13.1 mm to 26.2 mm is it ok / If no than please let me know way i can't set this range.

 

And weld metal thickness range for GTAW - 14 mm and SMAW - 18.5 mm .

 

Please give with details explanation regarding my above difficulty.

 

Thanks and Regards

RE: [MW:29749] Abridged summary of materials-welding@googlegroups.com - 4 updates in 4 topics

Hi,

Please see some extracts from a publication of Metrode, which provides some guidelines on the hardness requirements for grade 92 steel. You may find the same information in ASTM/ASME specifications also. To reduce hardness , additional SR would be necessary.

While performing welding of any CSEF steel(as P-92), it's advisable to keep Radiography before SR as an optional step depending on the joint thickness, criticality of the component, and many more…. so as to avoid any unpleasant situation as above.

Thanks.

Dear Experts,

 

I have one situation I have a job of material SA 182 F92. Hardness required for this material is 269 HBW Max. We had weld the F92 to F92 material. After PWHT we got Hardness around 250 HBW. But after Radiography it was one defect and we repair it. Now the Hardness of repaired portion is around 340 HBW. Now how we reduce it. And what is the Hardness limit of F92 Weld joints ?
