GD2 Column is of ASME sec VIII dIV.1 with following parameters:
Design Pressure: 8 Barg
Design Temperature: 670 Deg.C
Design Life: 30 Years
Material: SA 240 304 (We are proposing dual grade 304/304H)
TGS4, I am working on preparing calculation sheet based on code case 2951, my one concerns is what is impact if design life is more than 100000 hours. In My case design life is 30 years.
Noted, I will look into load cases, but since I have not worked on such high temperature vessel so my initial question are:
1 & 3- Base on 30 years life hours are 262,800. This is much more than 100,000 Hours. My question what should be my first step? what should I tell to my engineering...
I am working on vessels with 8 barg design pressure @ 670 Deg C and full vacuum @ 670 deg C.
1- When I use SA 240 304H, I get message in material window of Pvelite that "Ultimate tensile strength at external pressure is out of range". The same error is not coming with 304.In table U of ASME...
I have a client specification, and project has high temperature equipment 670 Deg C in which outer ring and inner ring for gasket is required. Datasheet says "The contractor shall verify
the adequacy of all gaskets considering potential buckling of the outer centering or inner ring(s) and the...
Hi,
I will be buying personal laptop to learn and practice Ansys workbench. As a beginner I have following question:
1- how to download Ansys workbench less expensive version.
2- when buying laptop what should be good feature for fast processing.
3- any website having good material for...
There is no material study/CMP . My understanding is first they just want to just rerun the ASME calculation on software to know if there will some impact due to reduced thickness. To be honest I am not 100% sure why they want to remodel. Above are just my assumption as base line.
I have a proposal in which I will have to verify and model couple of pressure vessels on PVElite. I am not sure exact why they want to remodel them. I have raised below clarification. Kindly comment if someone has done similar task:
1- Our scope is to verify existing pressure vessel as per...
So in the light of ur answer these are the main things:
1-Evaluation as per Api 653
2-Checking for the requirement of internal lining
3-Performing venting calculation as per API 2000
4-Checking of foundation against new loads as water has higher sg, but do we need to check other new foundation...
Hi,
We have and oil tank which client wants to be used for water now. We have to give a scope of work for this job. my understanding is that our scope of work will include following things:
1- complete on site inspection of tank as per API 653(we will sub-contract this work)
2- from inspection...
when giving weld size in ASME pressure vessel, do we need to follow AWS 1.1. For example when joining single bevel plates butt weld size is normally 60 degree? What is the basis of this?
Actually in Aramco standard following in written, so in the light of below requirement from client,heat cycles need to be performed??
12.1.9 Materials of construction (pressure-retaining parts of vessel and non-pressure retaining attachments) shall be tested to verify that their mechanical...
Due to Sour service in one equipment i am working on, PWHT is required, secondly heads need to be normalized also . material of the vessel is SA 516 Gr 70 normalized and impact test also required. In this case do we need to inform mill to perform 3 cycles for simulated heat treatment??
