I see the term " Lethal Service " as a category in ASME section VIII for vessel design/ Fab. anyone know where I can find a definition as related to section VIII , also would " Anhydrous Ammonia" be considered lethal, I realize its dangerous but does VIII consider it" Lethal Service" thanks

looking for some direction ,I looked through ASME VIII which refers to ASME V for ultrasonic examination techniques for inspection of Viii vessels ,I keep hearing that Section VIII requires Phased array inspection methods I cant find any reference to this in Section V. Most of our clients...

if your certified to ASNt level II for UT which meets AWS d.1 are there any additional requirements to examine welds fabricated under AWS d1.8

can anyone point me to a guide for this standard. I hold ASNT certs have a client that needs some inspection done and the manufacturer has referenced iso 9712 the equipment was fabricated in Europe

this should be pretty basis but its been a while i wanted to check how do I account for the moment of inertia of a beam that has a slot in the center .

that's basically what we looked at thanks for the info.

25K total tank & contents wgt. 4 legs 10' c-c with 12" sq pads I think the slab works as is

we have a existing warehouse slab d=8" 4000 f'c , someone decided to put #4's @ 10" c-c on top of slab no bottom steel ( ?) , we ran some numbers and came up with bottom surface concrete tension @ 110 psi looking for allowable concrete tension I seem to remember 75 psi , looking for...

my experience with UT examination of structural welds is with AWS D1.1 , I have a client who I have worked for in the past that has a issue that came up on a site , the third party UT examiner rejected a number of full penetration welds based on AWS d1.8 however the project only required the...

thanks guys we'll see

We provide NDE services to several clients, we have one that quoting a new boiler install , the owner provided a list of welds to be x-rayed which includes 815 socket welds sizes 1/2-1.5" , I have done this is the past to check for pull-back , socket welds are fillet welds ,we usually dye pen...

david339933 is right

then I see no benefit to QW423.1 , why offer a alternative to the base metal specified in the WPS if in you opinion you have to have a WPS for every combination of base metals , just do the combination WPS, why put it in code

if as stated if he took a test welding P45-P45 under a WPS established for P45-P45 and as you stated he now qualified t weld P45-P1 , what WPS is he qualified to , if he qualified to the original P45 WPS then he is qualified to weld production P45-P1 welds under that WPS .otherwise I don't see...

seems these two post don't agree, I understand procedure vs welder quals. QW 423.1 offers a method of using alternative to the mat. used in a WPS and allows for the qualification to extend to the P numbers listed in the right col. as long as all other variables in the WPS are followed . what...
