Hello all...
Question, I have a 3 stage helical gearbox, ratio 200:1, with 13,000Nm max output torque.
I am trying to determine the maximum, no load, input speed allowable in such a gearbox. Under full load it is rated up to 3000 rpm.
Does anyone have any helpful rules of thumb or guidance I...
Hello All,
I need some 28" Pipe w/ 5/8" or 3/4" wall thickness fabricated from a material with min yield of 50ksi or greater.
ASME B31.3 shows many grades which meet the material requirements, but I am not sure if any of them come as seamless 28".
I would relax my requirements to ERW if I...
Hello,
I've been searching to fine the galvanic reaction between these two materials used in a flowing seawater application. The Duplex will have a very small exposed area and the Inconel will have a rather large exposed area, they are both in close contact with each other.
I have also been...
Hello,
I am wondering if areas under B31.3 jurisdiction will allow ASME Section VIII Division 1 vessels or other components in the pipeline with no further analysis on the component beyond that as required by Section VIII.
I know for "unlisted components" B31.3 directs you to ASME Section...
I generally do design to Section VIII where there are specific nameplate requirements that go on each vessel.
Now I have a small job to do with simple spool piece per 31.3. And, I am having a hard time finding any requirements for marking the spool to indicate its design temperature and...
I originally started this thread under the Boiler and Pressure Vessel engineering Forum. I am hoping we can get some more answers by also posting here. Please follow the link to get back to the original thread. Thank You!

I am creating this thread so we may have a summary of everyone's input on how we can go about drilling radial holes in an ASME B16.5 flange.
Some questions I would like to try to address are:
- Does a hole through (Temp or Pressure port) vs. a blind hole (lift lug or lift eye) get handled...
I have an application where a number of branch connections and a section of run pipe are cast into a special fitting. The cast boss for the branches however is not cylindrical, it actually contains many of the branches in the single boss. The bores for each branch however are cylindrical. I...
I was wondering if anyone knew of a standard or set of minimum requirements for a typical Material Test Report.
Here at work we generally see an ASTM or ASME number, a chemical analysis and a mechanical strength analysis.
Recently we received an MTR that had an ASTM number and a chemical...
I work on a product that is comprised of a series of items that get stacked together. They are all relatively large diameter and varying thicknesses. Also, they are not all the same diameter, or even concentric. In order to fasten the assembly together, we have a "global" hole pattern that...
I'm trying to figure out what note (A) of Table 2 of the material specification for SB-171/SB-171M in 2007 Section II, Part B is telling me.
The note reads: "(A) When tolerances are specified as all plus or all minus, double the values given."
The table is titled "Thickness Tolerances, Plus...
I am trying to understand how IV uses the K Factor in sheet metal bending. If I create a bent "angle iron" shape, the bend line does not show up where I'd expect it to, and there seems to be no setting I can change to move the bend line. I am assuming the K Factor is used to affect this, but...
This publication was put out by ASME in 1972. I've seen it referred to in many places, however, I cannot find a copy anywhere. Does anyone know somewhere that offers it?
Any help is appreciated.
Thanks!
