Dear all,
In the case of a elliptical flat plate to be used as internal cover of a manway, what value should be used as factor C for the calculation of the required thickness of the plate?
I looked in Fig. PG-31 of ASME code Section I and I'm not sure which one is applicable to this case...
Dear all,
Does anybody know any information about corrosion rates of glycerin in carbon steel?
I'm evaluating a storage tank which will store this product and I have to estimate the corrosion allowance.
Thanks in advance.
I intend to buy a storage tank design software and would like to know the pros and cons of each software. I made a research in the internet and found the following:
Tank
Tri*Tank650/620
Etank 2000
Which one do you think is the best purchase?
I intend to buy a pipe stress analysis software and would like to know the pros and cons of each software. I made a research in the internet and found the following:
Caesar II
Caepipe
Autopipe
Triflex
Which one do you think is the best purchase?
Dear all,
In the case of an elliptical manway like the one shown in the attached picture, how should I calculate the required thickness of the elliptical cover?
In some catalogs the thickness specified by the manufacturer seems too small. For example: a 12x16 manway specified to 700psi @ 650F...

Please, verify if my interpretation of the code is correct:
In the case of a elliptical (12x16in) flanged-in opening in a elliptical 24in head we have two options:
1- Flued opening such as indicated in Fig. UG-38;
2- Opening with ring such as Fig. PG-28.
In the first case, the thickness of...

How do I design an elliptical manhole per asme section I? Can anybody send me or indicate where can I find drawings or pictures of this type of configuration?
Thanks in advance.
Dear all,
Can anybody help me with Section I calculation?
In PFT-51.1.2, the code describes the method for evaluation of the maximum allowable external working pressure, which is just like Sec. VIII procedure. However, in the case of a cylinder with definite pattern openings, what...
Dear all,
In PFT-51.1.2, the code describes the method for evaluation of the maximum allowable external working pressure. In the case of a cylinder with definite pattern openings, what consideration should I use to consider these openings? Should I include the ligament efficiency?
Best regards.
Can anybody explain me what is the angle referred in Fig. PG-33.3? I'm having trouble computing this factor F for a radial nozzle in a cylindrical shell.
Thanks.
Dear all,
In paragraph PG-27.2.2 of ASME Section I (2007), the code indicates the formulae for calculation of thickness and pressure of cylindrical components under internal pressure. In the formulae, the efficiency E is described as:
1,00 for seamless or welded cylinders; or
efficiency from...
Dear all,
My client is requesting the use of 317L seamless tubes for a heat exchanger. However, I cannot find this material in ASME II Part D.
Can anybody help me with this?
Thanks,
Fabiano Rosa.
Dear all,
I have a doubt about nozzle calculation in ASME VIII Div 2.
For a radial nozzle in a cylindrical shell, for example, ASME gives a procedure for the calculation of its MAWP.
In the equation for Pmax2 (formulae 4.5.44) , ASME says that S is the allowable stress for the vessel. What...
