RE: [MW:13772] Incomplete pen vide B31.3 2004 Ed

My dear, IP is in the root, right? In 8" pipe VT is obviously out ruled. My question is, IP being a serious discontinuity, how is it acceptable even for normal fluid service? IQI contrast - indication density, etc is bit untidy, but the main question is not that.

But in RT you can approximately identify( Not measure) the depth by difference in contrast relative to the IQI contrast at that location BR M.

RE: [MW:13771] Acceptance Criteria For Chemical Contents Inconel 625 Overlay

Dear Sir,  I fully agree that Inconel 625 (EQNiCrMo3) we can achieve with two layers and Not with single layer of total weld overlay thickness of 7mm By ESSC process with proper magnetic stirring device adjustment  and we can generally get undiluted chemistry at 5-6mm from base line(Particularly of Fe less than 5%   Regards   Hegde P.B.

[MW:13769] THK calculation on grid size

Dear Experts, In NPCIL project specification for seamless Alloy steel fittings,following sentence will be given as - Minimum thk will be calculated on grid size minimum 30mm for up to 50NB & 50mm for up to 500NB & 100mm for above size. I never heard about this, I want some information regarding this matter.

RE: [MW:13769] Acceptance Criteria For Chemical Contents Inconel 625 Overlay

Dear Mr. Goswami,   Sorry for the late respond due to my current assignment. There is no client specification for this except they only specified inconel 625 overlay 3 mm thickness. We have done experiments with ESSC using single pass (4.5 mm height)  and the 2 layers (9mm height). The following is results at the various location.   Profab 1 st Testing (taken 1.5 mm from the surface) Overlay thickness 4.5 mm Profab 2nd Testing (taken 0.5 mm below surface) Overlay thickness 4.5 mm Profab 3rd Testing (take 4mm below surface Overlay thickness 4.5 mm 0.024 0.022 0.016 0.38 0.32 0.27 0.39 0.33 0.46 19.1 19.3 22.4 56.7 58.6 62.3 7.74 7.86 9.45 2.23 2.12 2.46 12.5 10.4 1.53 0....
