I have the smae problem with Inventor 9. It is incredibly frustrating, especially since I have invested so much time in the assembly at this stage. Good luck to you...I am ready to go back to AutoCAD!

We are engineers currently using AutoCAD. We have purchased a few seats of Inventor 9 and are currently evaluating its potential. We have some concerns. I thought this forum could add some insight....

It is technically a flushing system. I mistakenly used the terminology of barrier fluid, since it is a bouble seal, thus creating a pressure barrier (net 0 leakage of process fluid into atmosphere).
Any insight on "flush" oils?

We are designing equipment using FLowserve mechanical seals. We originally intended to use Royal Purple GT78 (www.royalpurple.com/prodsi/bfgt.html) as the barrier fluid (1.0 gpm flush @ 300F inlet temp).
Now, the end-user has asked us to address switching from GT78 to Methyl Oleate or...
I have heard about an o-ring groove design in which the ID of the oring is exposed to the ID of sealed vessel and the groove is circular. This is apparently done to facilitate cleaning. Does anyone know where I might get dimensions, specs and/or further information on these food-grade o-ring...
We are about to hydrotest, then ship some large equipment. We typically make this equipment in Stainless steel, however this latest batch is made of 516G70 carbon steel. (2) questions:
1) Can anyone recommend an additive to put in the hydro fluid that might slow oxidation of the inner...
We usually use SA-106B seamless pipe, but due to size and availability issues are now contemplating the use of API 6L GrB PSL1.
I have the chemical, mechanical, and hydrotest specs, but haven't been able to find the welding NDE specs of the pipe. Does anyone have a quick reference or know of...
Thanks for the responses. The idea of an argon or nitrogen blanket during PWHT has been floated to avoid even the slightest chance of oxidation. Any thoughts?

I am currently involved in the design of a jacketed pressure vessel. Per the ASME code, we are required to complete a PWHT. The vessel is very simple and there is nothing out-of-the ordinary with the design. However, we are concerned that a PWHT would create scale/oxidation inside the jacket...
