Thanks for the replies. With respect to NACE, it is not a requirement, but the equipment could be used in a sour environment and it will be in tension so i am using NACE more as a guideline than a requirement. I think MP35N etc is on the expensive side for a part that we will break from time to...

Hello I am looking for a material that will fail without work hardening during operation. The application is a failsafe piece that can break to prevent damage to other more expensive equipment. The operation is fairly rough and ready with shock loading and potential impact. Based on that the...

Thanks for the info RP. Maybe it's that Friday feeling, but i don't see where you get the 500 (well 499.5) ratio of rod diameter to bend radius. The manufacturer has quoted a minimum bend radius of 1.4m. perhaps this is empirical based on low cycle fatigue or something though. Your info has...

Hello Is there a standard methodology for calculating the theoretical minimum bend radius of composite rod. I have a spoolable 10 mm dia rod and I want to know what the minimum drum diameter that i can spool it onto is. Ultimately I want to use this formula to run a numerical optimization to...

Im using 2007. I tried removing all the colours/textures that I seen when I clicked the chevron and nothing happened. I cant even apply anything over the top of it. The only way I can get rid of it is to right and do "delete face" then choose "delete and fill.

I have a cylindrical part that is showing a shaded cosmetic thread on the OD. I have tried deleting all my cosmetic threads and it is still there. Has anybody had this problem before?

Are u running 2008 as I am using 2007 and can't see the check box :-(

Is it possible to display the units of a dual dimension, ie showing it as [3.00mm] instead of [3.00]

I am working on a check valve that has an o-ring in a groove on a conical (30deg) face and uses a spring to energize the seal. Does anybody know how I can estimate the required force (hence which spring to use) to energise the o-ring seal.

thanks very much, this has done the trick

I have an assembly that has several configurations, all of which are the same assembly in different positions. In my assy drawing the BOM is coming in with the configuration name and qty. Is there a way to change the cell to display "qty" only and omit the configuration name. I have tried...

the tubing thread is not a sealing thread, there is an o-ring on the pin situated in such a way that any radial loading should not affect the integrity of the seal. I am concerned with the mechanical integrity of the connecting thread. I have calculated the maximum permissable force based on the...

Sorry I have should have said in the original post, but what is confusing me is that the weak point of the threaded connection is the shear across the teeth. Hence it seems oversimplisitc to algebracally add the stress induced from the bending moment. Does this change what has been said in the...

I am working on a problem that invloves a threaded tubular that is situated vertically with the lower end being screwed into a base part, the upper end of the tubing is blanked off. I am trying to analyse the effect the bending moment caused by the wind will have on the integrity of the...

Thanks very much - easy when you know how :-)

Hi, I recently changed jobs and am now using Solidworks as opposed to Pro/E and have what I think will be an easy question for more experienced Solidworks users: What creating a drawing in Pro/E I could add dimensional properties (ie a length) to a note by adding its name with an & prefix to a...

Thanks very much for all ur help on this matter. I have managed to get this and other librarys features working as planned now :-)

As requested, here is the SW filehttp://files.engineering.com/getfile.aspx?folder=2c4b647b-5d07-4cb8-8667-0977a7a461b7&file=PIN_OTIS_QUICK_UNION.SLDLFP

Here is a screen grab of my sketch to see if this can shed some more light on the matter, as I tried playing around with relations etc, to no avail. The basic crux of the matter if that the pin I am trying to make a library feature has to be able to flip depending on which side of my sketch I...

I have created a simple revolved feature, however when I insert it into a part it can only be orientated one way. I imagine that there will be an easy fix for this, but unfortunately I cannot find it. To create the library feature I used the OD of the base cylinder as a reference, then also used...
