Hi, I'm looking for a supplier for 316L pipes (in Canada or US) for high pressure/Temperature application (300 psi and 1200 degrees F) Any help is appreciated.

Thanks rmw for this website. toothless, The steam generated from the HRSG will be used for process and to run a steam turbine to generate electricity. The condensing steam from the steam turbine will be condensed and than pumped to the HRSG. Cheers

Thank a lot "arto" Excellent Site. Cheers

poetix99, Thank you for the info.

Hi We have a HRSG system that uses the hot exhaust gas of a gas turbine to generate steam. This steam will be used to drive a steam turbine to generate ectectricity. I know: the turbine inlet mass flow rate, Temperature, and pressure of steam. How do I know the outlet pressure from the...

Hi, Can anyone tell me how to model welds in Ansys. Any help would be appreciated. Elias

Hi Jan, After a dicussion with Drej (see "Cylindrical Constraints in Ansys" post that I initiated a couple of days ago. It seems that you cannot use angular acceleration or velocity as a load in a transient analysis in ansys and expect your part to rotate. knowing that linear acceleration and...

Harid, I don't have Ansys Workbench (I use Ansys 8.0). But the procedure should be the same (I hope). 1. Build and mesh your model, apply the 1000N force (Load Step 1) and finally solve it. 2. apply the cyclic force (Load Step 2) and solve it. (Check "loads" in HELP file, this should give oyu...

Drej, I'm trying to analysis the stresses induced in a Silicone Chip resting on a polishing disk as it accelerates from zero speed to a specified one at time T). that is why I need the acceleration in a transient analysis. Thank for your help, Elias

Drej, I'm applying the acceleration DOMEGA as a stepped load in the transient analysis. Normally the disk should start rotating 'till it reaches a OMEGA = DOMEGA * time. I tried a solid disk (constrain its central node radially) and applied the angular acceleration for 0.5 second as a stepped...

thank Drej, I did that (rotated only the inner circle nodes and applied the radial contraints. I appplied a global angular acceleration of 3.14 rd/sec^2 on the disk and ran a transient analysis for 0.5 seconds. When I checked the position of a specific node on the disk (it didn't move at all)...

thank you for replying, I rotated all nodes into the cylindrical system (is this correct?) I only applied the Ux=0 constraint to the inner circle What am i missing?

Garvin, Did you manage to get it work? I'm trying to simulate a 2D rotating disk on a polishing Jig. I created and meshed the disk (hollow disk). I rotated the nodes to Active cylindrical coordinate. 1. I applied Ux = 0(radial coordinate) on inside circumference of the disk. 2. I applied...
