Hello Folks!
I am just want to know how to correctly apply the ANSYS Transient-Thermal analysis with a Structural analysis in order to perform a complete welding simulation and visualise the final distortion and residual stress field.
I have done some thermal simulations with appropriate...
Hello all!
I have a series of specs which asks for the use of the 17-4 H1150 Precipitation Hardening Stainless Steels in the stem and trunnion of ball valves.
Until now, what I know is that this is a very good material for corrosion and high yield and tensile stress.
The use is in the entry...
Hello folks!
I am taking an specialization on Welding Engineering and I need to do a final monography. I tried to take a look on good tremes for the Oil and Gas Industry on Welding Magazines but could not get a good view on which Theme could be good and interesting to decide.
Could someone...
Hello all!
Is there any specific criteria (temperature, material, etc.) to use coated carbon steel bolts instead of alloy steel bolts in stainless steel piping or machine anchoring?
Hello all!
I have an interesting issue here about the interaction between mechanical engineering and instrumentation engineering.
It came to my hands the ASME PTC 19.3 (2010) which scope is just about designing thermowells against resonance and fatigue. It is a really interesting norm that...
Hi There,
The problem is: I have a duct carrying a high temperature stream. I have modeled the problem this way:
I was asking my self if, inside the pipe where there is a 515°C hot air stream, radiation occurs together with the forced convecction.
Thanks
I have a carbon steel (CS) use at high temperatures issue here . We are just finishing the construction of a Reformer Furnace for a Hydrogen Generating Unit. The designer / supplier used ASTM A36 on an expansion joint on a breeching duct that is subjected to a 515°C stream.
It is fact that the...
I work for a big Oil & Gas firm that prohibits the use of threaded joints for pipes carrying flammable fluids (gasoline, diesel, naphtha, natural gas, LPG or whatever) subjected to any pressure or any temperature.
For example, when we acquire a machine, we have to make them seal all the...
