I was under the impression that the 12.5% undertolerance concession applied to ALL pipe regardless of whether it was seamless or not.

If they put an image that represented the specific code on each different one they would charge even more for them. Do you really want that?

Hello All, I have been asked to find out first of all whether or not hydro-testing is required after repair work is done on an ASME code vessel, and secondly where this is referenced in the NBIC rules for repair. Thanks for any help.

Hello all, I am new to engineering and as such need some advice. I have been asked to find out whether or not inspection openings are required in between welded in plates (i.e. distribution plates). My boss seems to think that this used to be a Section IIIV-1 requirement, but he believes it...

Hello All, I would like to know if there is a section in the ASME VIII-1 which deals with flat circular heads with a spoke pattern of stiffeners. I have not been able to find it, unless maybe I can adapt the section on braced and stayed surfaces (UG-47), but I'm not sure how to do that either...

I am new to this company and have been told that in the past we have attemped to go without the stress relief and have experienced problems in attempting to do the finish machine work. Suffice to say that I am in the situation of being told that a stress relief heat treatment will be done and I...

Yes there is to be machining done after the welding and tolerances are down to the thousandth of and inch, so movement during this process is very undesirable. David

Hello all, I am a new M.E. and am having a difficult time finding information on stress relieving heat treatments of austenitic stainless steels (particularly 316L and Alloy 20 welded together). ASME IIIV-1 simply says it is neither required nor prohibited and nothing else. So far in my...

Does anyone know if I design a flange using Appendix Y. Do I need to do the rigidity check from Appendix 2?
