What is considered a code part under ASME Section VIII, Div. 1 or when does a part require a partial data report?
For instance is a simple plate such as a pipe support clip considered a part?
What about welding plates together for a non-pressure part to be installed on a vessel?
Can a repair or alteration to a pressure vessel result in a decreased joint efficiency, given the calculations are done to support the new joint efficiency?
We have a vessel repair that we will not be able to perform 100% RT of the repair as would be required for a 100% Joint Efficiency.
If we...
Can materials certified to ASTM specification be used for a non pressure part welded to a pressure vessel fabricated under Section VIII Division 1?
Can ASTM A572-50 be used for a bracket?
Can a wide-flange beam be welded directly to a vessel?
Is a re-hydrotest required for routine repairs?
We have a Section VIII Div. 1 vessel recently completed and now we must weld a small bracket inside.
This will qualify as a routine repair and we are not altering the pressure boundary other than welding about 3".
Do we need to re-hydrotest the...
ASCE specifies the following load combination in Section 2.4 for ASD:
8. 0.6D + 0.7E
In reviewing the Compress report on a vessel this is noted in the seismic code, but when any of the components are checked for seismic loads the equations apply the following load combination:
0.6D + 1.0E...
I have an application where some stud bolts need to be plug welded into a hole in a plate.
Normally we would use A307 stud bolts, but this project has a high temperature application which A307 would not be suitable.
Is there another type of bolting material that is weldable with a higher...
I am looking for a class to become more familiar with steel design, particularly AISC design methods.
I found this site: [link steelclass.com]steelclass.com[/url] which appears to be a good option.
Has anybody had any experience with this site or can anyone recommend another option?
Thank you...
My company is replacing some existing steel water pipe and I have been asked to review the some of the pipe joint reinforcements on the existing pipe.
The joints have some strange looking plates welded to them that I have never seen before...
I have been asked to help design a removable false bottom inside of a vertical pressure vessel.
I am wondering if there is anyone that has done something like this that can give any advice or recommended literature.
The vessel is 11'-0" diameter and the false bottom is to be designed for 90...
We have a frame being fabricated that requires a splice in one of the tubes.
We have two options of where to place the splice depending on which way we flip the tube.
Option A puts the splice directly over a connection point where another tube would be welded over the splice.
Option B would...
Hello,
I work for a company that fabricates API-650 shop assembled tanks.
I often see tanks that only have repads on the manways of tanks. Due to the size of these tanks there is often no need for repads according to the requirements 5.7.2 .
Is there some other requirement or reason that...
