Hi all,
I understand that EN 1092-1 flange standard has replaced several DIN standards.
My question is: comparing, for example, PN 10 welding neck flanges as per DIN 2632 vs. the equivalent flangse as per EN 1092-1 standard (type 11) the EN standard flanges are longer (h1) and thicker (c2) -...
Hi all,
I have a question regarding a steel pipe which will be buried in an embankment. Using the Marston-Spangler theory, the dead load on top of the pipe will be the full amount of the soil prism above the pipe, I get that.
My question lies with the way to determine the pipe's deflection: is...
Hi all,
I have an old self-lubricating bushing specification - Dorcolube Kingwell, Bronze Alloy E Type as per ASTM B22.
Does anybody know what company supplied / used to supply this? Has anybody ever came across this spec?
I found a deceased company called Kingwell Bros. Ltd. that, as far as...
Hi all,
I'm trying to calculate a loose flange (sketch 3a of fig 2-4) that will be fabricated. I've started out with the dimensions of a DIN 2575 flange (same as EN 1092 Type 1). I'm going to use a Klingersil C-4324 gasket.
Now, my problem is that the stresses I get are nowhere near the...
Hi all,
Does anybody have an article by one J. Dutheil (French?) about the formulation to determine the buckling of circular rings (penstocks) subjected to inner void? I have the calculation method prescribed in this article but I can't understand some of the formulas, so I would like to know...
Hi,
Does anybody have a CAD block of a trash rack cleaner? See attached picture for reference.
I just want a schematic block to insert on a tender drawing so that the developer gets the idea.
Alternatively, I'm going to put an adapted excavator.
Thanks.
The design of an anchor bolt's length should be considered as serviceability or ultimate limit state?
I'm reviewing a project and the engineer who made it calculated it as serviceability, thus reducing the loads, but I think it shoud definitely be ultimate limit state.
I thank you in advance...
Hi,
I'm designing a flange for a piping with ASME Sec. 8 Div. 1 Appendix 2.
I have to combine force due to Poisson + force due to temperature. My question is: do I combine them 1 x Poisson + 1 x Temperature or there are reducing coefficients?
I thank you in advance.
I'm a recently graduated Civil Engineer and I'm a bit clueless about something my boss asked me to do.
I am supposed to check if the foundations of some highway signs are properly or overly designed. The signs are supported by 3 steel columns which are 4.3' embedded in the continuous concrete...
