Typical design velocity for crude oil in shell & tube heat exchangers is around 1-2 m/s in the tubes and 0.3-1 m/s in the shell, but it depends on factors like fouling and pressure drop limits. Check TEMA Standards under the 'Mechanical Design' and 'Thermal Design' sections for specific...
Yes, ASME Section IX QW-200.4 allows combining WPSs if both are qualified separately. Your GTAW root (NCBWB 1-32-1) and SMAW 6010 fill/cap (NCPWB 1-1-2) can be combined as long as they each meet the essential variable requirements.
For thickness range:
Check QW-451 for qualified ranges based...
The note means that some cap dimensions fall outside the standard calculation methods in Annex B, so their pressure ratings aren't predefined. They’re still listed in the standard because they exist in common usage, but their usability needs to be checked case by case—either by engineering...
You’ll need to consider pressure drop due to friction losses in the tubing and the flow characteristics of your vacuum pump. The Darcy-Weisbach equation can help estimate pressure losses along the line, and you’ll also need the pump’s performance curve to determine the pressure at the membrane...
I've worked with D6-55441 for cabin structures before, and from my experience, the decision depends on load path complexity and attachment flexibility. Generally, if the mounting points are significantly stiff relative to the component, a rigid support assumption is reasonable. However, if...
Hey, sounds like you're on the right track! YouTube is a great resource, but I'd also recommend checking out the official RAM Structural System manuals and Bentley's learning resources if you haven’t already. Best way to learn is by building simple models first—start with a basic frame, play...
