Thanks for sharing

Dear,

Could you please mention the ASME BPV section and clause for reference?

Regards,

Inconel

For CARBON:
8. ASME B&PV code prohibits welding or thermal cutting of carbon or alloy steel with a carbon content of over 0.35%. Higher carbon can cause zones of high hardness and impart adverse ...

Thank you everybody for your valuable reply

Dear All,

We have WPS qualified for API 5L Gr X 65 to API -5L Gr X42,X52 and dual X60/X65 welding done with SMAW process, electrode used for root is E 7010P1 and rest with E 8018C3.My query is can we do welding with same WPS for API 5L Gr X 60 to API 5L Gr X 60 OR should we qualify new WPS for X60 ...

@mechcolor,

Dear Friend,

So far no mill has disclosed how will they perform NACT (complete cycle and cooling rates).Do you have any info. regarding procedure of NACT operation from any steel manufacturer ?Please let me know is there any problem for doing PWHT above tempering temperature?

Regards ...

Ashfaq,

This is for pressure vessel shell plates.

Hi,
Usually thickness of cladding is not considered to contribute either partially or fully to design thickness unless this thickness is included during min. thickness(design thickness) calculation for that vessel. Damaged/corroded shell plate may be repaired by removing a section and replacing it ...

Dear all

Please share views on heat treat ment carried above tempering temperature for NACT plates? one of the case i have come across is stated below.


MOC: SA387 Gr11, Thickness 90mm, Delivery condition: Normalised+accelerated cooled+tempered (NACT)
Contract requirement: Cold formed D''end shall ...

you can use E-7018B2L (not E-7018B2). the “L-Grades” are limited to a maximum of 0.05% carbon. While the lower percent carbon in the weld metal will improve ductility and lower hardness,it will also reduce the high-temperature strength and creep resistance of the weld metal.


Generally it is not a ...
