Ask to your customer, if you explain that pipes your are offering are better maybe there is no problem, psl2 pipes have more rigorous quality control, among others in ChemiCal composition, in mechanical properties specially toughness.

Hi everyone,though therotically Maximum Temperature limit of C.S is 425 degree celcius but you refer some practical standard of API it will allow use of c.s. above 425 degree celcius. any how its tube so obiviously threre will be less welding so the rate of carbide formation will be less. i dont think so it will be issue for 1 hour On Tue, Sep 30, 2014 at 5:15 PM, pgoswami < pgoswami@quickclic.net > wrote: Hi Jignesh and Dr Dilintas,   A short note on this scenario, from Utility Operators point of view.

Design Code : ASME Sec I, API 560 & API 530 Service: Non Corrosive. We have CS tubes in the convection section (BFW service) of furnace and we are planning to operate during the emergency shut down (plant black out) for short duration of about an hour at higher temperature then the design temp.  (425° C).  At this short duration of time the water tubes is going to see the no BFW flow condition (DRY). Query: What is the max. temperature attainable (intermittent - 01 hour) by CS tubes (to avoid creep rupture). How much the temperature above the design temperature (425° C) can the CS tube be pushed for this short operation of time (01 hour)?

Dear sir  Please note that carrying out tube to tubesheet mock up before actual welding On job is the intent of the code. This involves the actual welding variables and sequence to be followed on job. You should weld the mock up simulating actual job condition and sequence. I.e. Do exactly same on mock up what you want to do on job. For your query regarding combining two mock up qualifications.  Ask your AI or concerned tpi for its acceptance. In this case they may refuse you proposal of combining two PQRs because it is not simulating actual job conditions.  Anyway you talk with them and proceed.

Difficult to relay ,i dont think so welder need to know about chemical properties of metal On Sat, Sep 27, 2014 at 4:29 PM, Rems Okonkwo < rems.okonkwo@gmail.com > wrote: Dear Mohit,   F Number is an essential variable for welders qualification. If the F-No used in the CS does not cover that to be used for the Overlay as per QW-433 , then the welder is not qualified to perform such overlay. In any case, you will also need to consider the requirement of QW-381.3.   Dear Mahendra,   When a chemical composition is stipulated in the WPS, it simple implies that every weld performed must meet the stipulated chemical composition and chemical analysis of the production weld may be required by spot check. It is then a requirement that every welder must be qualified using that particular WPS and strickly following the weld parameters as stipulated in the WPS.   Regards,   Rems Okonkwo IWE Nigeria On Fri, Sep 26, 2014 at 7:26 PM, Mohit Aggarwal < aggarwalmohit05@...

Vijay,   Failure in sour -service environment (i.e wet H2S environment) is always related to hardness . Please see the introduction in MR-0175. Many materials may have higher Y.S but lower hardness, say 300 series S.S. Contents of  MR-0175 is self explanatory.   Thanks    Pradip Goswami, P.Eng,IWE Welding & Metallurgical Specialist Ontario, Canada pgoswami@quickclic.net pradip.goswami@gmail.com http://ca.linkedin.com/pub/pradip-goswami/5/985/299   Introduction The consequences of sudden failures of metallic oil and gas field components, associated with their exposure to H 2 S-containing production fluids, led to the preparation of the first edition of NACE MR0175, which was published in 1975 by the National Association of Corrosion Engineers, now known as NACE International. The original and subsequent editions of NACE MR0175 established limits of H 2 S partial pressure above which precautions ag...

PSL 2 is a higher quality standard than PSL and few clients would object to received PSL 2 in lieu of PSL1. However you need to declare to your client what you are providing. The leaner chemistry of PSL 2 could give strength issues if anyone were to make pipe bends by induction bending from the material.   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Nirav Sanghavi Sent: 29 September 2014 12:02 To: materials-welding@googlegroups.com Subject: [MW:22011] CS Pipe API5L / A106 GR.B/X42 P2 (PSL2) instead of API5L / A106 GR.B/X42 (PSL1)   Can we supply Carbon Steel Seamless Pipe API5L / A106 GR.B/X42 P2 (PSL2) instead of API5L / A106 GR.B/X42 (PSL1) Looking forward to your guidance.

I think during hardness you could find exact values related to each area (base metal, weld metal, fusion line and HAZ refer to hardness sketch) but in other tests such as tensile you will find a summary of properties for those areas together (that is not good for root cause analysis or developing design or fit for purpose).  Also if any doubt remain after hardness, it is practical that you check values again or doing retest. Also check values in relationship with microstructure which are not practical after destructive tests.
