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

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.

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.

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.

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.  -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

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 ran...

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 .

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.
