In fact you need to to look at D-10.10 for detailed  guidelines, assuming these pipes would not be heat treated in in furnace.   Thanks     Pradip Goswami, P.Eng,IWE Welding & Metallurgical Engineer/Specialist Ontario, Canada pgoswami@quickclic.net pradip.goswami@gmail.com   On Tuesday, May 26, 2015 at 10:19:30 AM UTC+5:30, Vishwas Keskar Welding Manager Pune India wrote: For long piping(Carbon steel, alloy stee...

If you have PQR of ENicrMo3 weld built up on P1 material to P43, then it is the best solution for this joint. If with PWHT with impact test vessel, then you should follow same procedure for this production joint. -- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Hi, SPWHT is mandatory for non standard forgings and plates. For standard products it is always a topic of argument with client. If you read 3.10 thoroughly for standard items like elbow, pipes and flanges it is not required. But if you think out of the box, if plate requires why not for other products? the main idea behind it is to check material properties after heat treatment. So client may insist for all the materials involved.  On Sat, May 30, 2015 at 1:25 PM, 'CHINTUKUMAR GANDHI' via Materials & Welding < materials-welding@googlegroups.com > wrote: Dear Experts, Greetings of the day.

My question is regarding the PWHT requirements for above vessels, 1.Does the shell to nozzle weld edges to be buttered by Er NiCrMo-3 before PWHT and groove welding by Er NiCrMo-3 after PWHT? YES. or 2.Or a PQR of dissimilar joint P1 to P43 with PWHT (of P1 requirements) can be used directly? P43PWHT NOT RECCOMENDED.HENCE GO WITH OPTION ABOVE. UNF 56 : Does not address such dissimilar joint UNF-56 POSTWELD HEAT TREATMENT (a) Postweld heat treatment of nonferrous materials is not normally necessary nor desirable.

Product analysis is a responsibility of manufacturer of the parts, who has access to the billet which parts made from (by forging, rolling, welding or some times re-casting).  If a manufacturer uses a process without any secondary casting to produce a part (forging, rolling, ...) then, the chemical analysis from the initial billet uses for evaluation of heat analysis.  If he uses process\processes which include remelting and casting for producing parts, then the analysis should be held after this casting process and assumes as heat analysis. You as a user of such parts should evaluate the conformance of that part with related standard by testing it according to that standard, which one may be chemical analysis. Such chemical analysis from final product is named as product analysis. Please note that the product may pass some stages between heat analysis and product analysis (machining, blasting, heat treatment, some nondestructive tests, coating or painting & ... but never casting)....

Dear All,             We all know that ASTM 105 & ASTM A 234 have their own General requirements given in ASTM A 960, A 961 etc. which should also be addressed along with original Product requirements.  Now as per A 960/ 961 : Heat Analysis : "An Analysis of each heat of steel shall be made by the manufacturer to determine the percentage of those element specified in the individual product specification. If secondary melting process are employed, the heat analysis shall be obtained from one re-melted ingot of each Primary melt . The chemical Analysis thus determined shall conform to the requirements of the individual product specification. Note that Product Analysis(Check analysis) tolerances are not to be applied to the heat analysis requirements."  Product Analysis:   If a Product Analysis is performed, it shall be in accordance with Test Methods, Practices & Terminology A 751. I have following questions for the above. 1. I want to...
