Hello Experts,
Could someone guide on CORROSION ALLOWANCE requirements on Heat Exchanger Tubes of different materials (including Carbon Steel) per requirements of VGB-S-110-R-00 (Heat exchangers and boilers in the steam-water cycle of thermal power plants). So, essentially for heat exchangers...
Hello Experts,
I have external nozzle loads provided by piping group and this needs validation by FEA (elastic analysis for now) for mechanical integrity (beyond WRC).
The piping guys have considered the actual Shell-Nozzle stiffness for arriving at the imposed loads.
My first question is -
1...
Hello Experts,
I from a mechanical background but seeking some advice on basic Sizing of a Vertical Flash Tank/Vessel WITHOUT Mesh Pad. The flow of incoming condensate is just 3000 lbs/hr (so low!). The vent and drain both go to a Surface Condenser of a power plant.
I searched on this forum...
Hello Experts,
Do we need to assess PROTECTION AGAINST LOCAL FAILURE for Hydro-test condition as well ? I have checked for PROTECTION AGAINST PLASTIC COLLAPSE by Limit Load Method with applicable load factors.
As i read through 5.3.2 Elastic Analysis — Triaxial Stress Limit, it guides on the...
Hello Experts,
Table 5.6 in ASME Sec VIII Div 2 gives examples for Stress Classification. I am trying to understand when on a FLAT HEAD junction to shell would one consider the bending stress as Primary Bending or Secondary.
Of course I read through the Note (2) If the bending moment at the...
Hello All,
I am doing Static Elastic Analysis for internally pressurized vessel which has stiffening rings around it. Note that this is not exactly a PV and these stiffening rings are not exactly for FV loading. I am using Shell Elements to model the entire geometry.
I have high stresses at...
Hello All,
This is regarding the Non-Mandatory App-A, Figure A-2 (Tube-to-Tubesheet Welds) in ASME Sec VIII Div 1 (2019 Ed.).
Could someone share some knowledge on when the Fig. A-2(b),(h),(i) are used. More specifically, I am curious about why the grooves are provided around the welds ...
Hello All,
Sec VIII Div 1 [UG-37 (c) & (d)] clearly states the Area compensation requirements for openings in shells for BOTH internal & external design pressure. Whereas, Sec I (PG-33) does not say distinctly on area compensation requirements separately for internal and external pressures...
Hi,
What could be the technical reasons when someone says, "the preferred tube layout pattern for hairpin heat exchangers is 90 degree" ?
What are all the reasons that make the 90 degree tube layout pattern suited for hairpin heat exchangers ?
Hello!
I am fairly new to automating CATIA via VBA.
I am able to create a new ParameterSet but i am unable to rename it using VBA.
For eg. the following code creates a Parameter Set with its name as per index of that ParameterSet:
Sub CATMain()
Set oDoc = CATIA.ActiveDocument
Set oPart =...
Hello Friends,
I am working on Stress Analysis of a complex Pipe routing using ROHR2 for analysis. i have modelled the pipes in CATIA V5R19 (.CATPart).. i know how to get files from PDMS to work in ROHR2.. but i have never imported files from CATIA to ROHR2.. Is there some alternative to this...
Hello Friends,
In an eralier post, i had requested a method to generate Balloons in drafting workbench of Oblong Shape and with Nomenclature Data.. (V5 R19)
i am only able to generate the balloons with circular shape and with part numbers at its best..
One of the kind members suggested an...
Hello Friends [glasses]
This is my First Post on this Forum!
I want to generate Balloons in the Drafting Workbench.. which takes value from Nomenclature and is of Oblong Shape..
i am only able to generate balloons with Circle and Part number at the best..
I am even not sure if a Macro is...
