Hi everybody,
In our projects of small diameter atmospheric tanks (Diameter < 4000mm x Height < 4000 mm) supplied in one piece ("complete shop assembly and delivery to the installation site in one piece"), stainless steel A240 TP 304L, we have used the API 650 code, from the code in the Annex...
We have a project where will be necessary to be executed tubes rolling expansion at site in an environment with temperatures about -30C, we have executed plenty of tube to tubesheet expansion at site but not at this low temperatures. The tubes and tubesheets are materials 304L, so probably no...
We have a pressure vessel supplier which asked us to use "inclined welds" in some shell elements from a pressure vessel, so in accordance their understanding as in ASME UW-3(a) it is informed that a spiral weld (type A) on the shell of a pressure vessel can be used, please may you inform your...
Hi,
Does anyone have information about API 650 online training?
I have tried to find it but no positive results.
If somebody know where I can find a set of slides with information from API 650 information for training, mainly about atmospheric tanks design, construction,... also will help a...
May anyone give me a recommendation to the Code for design / fabrication /... to be used for a vertical tower (dia 7 m lower cylinder x with 7m height / transition from dia 7 m to dia 14 m / upper cylinder with dia 14 m and 40m height), atmospheric equipment (only liquid up to the top), design...
When it is used an internal concrete lining (for instance 100 mm thickness), is there any reference for carbon steel atmospheric tanks’ shell and bottom "local deviations from theoretical shape" or tank shell out of roundness tolerances?
I know that in API 650 there are some tolerances for...
If I have to design a tank in accordance with API 650 , APPENDIX S (stainless steel tank),is it correct to consider different joint efficiencies (E) to be applied in the same shell but different shell elevations?
For instance, in order to reduce the shell thickness using E=1.0 on the lower part...
I have worked in an API 650 tank design, carbon steel ASTM A 36 and the maximum normal fluid operation temperature is 194 F (90 C).
Is it a must to consider the appendix M from API 650 if the design temperature is 230 F (110 C)?
This design temperature, in our case, is not a usual...
I know that it is not usual, but may somebody inform if there is any restriction in ASME Sec VIII Div 1 or other Sections to manufacture a PV with the direction of the plate conformation executated during the fabrication, parallel to the plate rolling direction (as received from the mill)? In...
Can somebody help me with the material specification UNS S 41003 (3Cr12) to be used in a pressure vessel design and in accordance with ASME Sec VIII Div 1:
1) Is it possible to use this material in a ASME PV? This question is because I can not find allowable stresses in ASME.
2) Is there any...
Please, somebody can inform which is the usual procedure to make the calculation of the anchor bolts from an API 620 tank with internal design pressure.
Thanks.
Please,
Have somebody worked with the material specification SA 302 Gr B?
Is there any special recommendation about the Pressure Vessels fabrication (conformation , welding, heat treatment,...) using this material specification?
Thanks.
I have worked in a boiler drum calculation with openings parallel to vessel axis, and concerning the ASME Sec I PG 27.2.2 and PG-52 I would like to know if somebody can give me some information about:
1) In the calculation of the drum thickness (cylinder), may I consider the efficiency 1.00 and...
