Hi All,
In my current project, I have a few heat exchangers which are stacked. And Iam using Microprotol for design. But the two exchangers have different design parameters. In Microprotol, if H.Ex is stacked, it assumes both has the same design parameters. Iam struck here.
My idea is to...
Hi Guys,
This is a tall equipment of about 45m high which consists of two columns with different diameters placed one above the another. The below column is welded to the head of the above column by a cone structure.
Now the entire column is designed for the given condition, But one more...
Hi Guys,
I have something to get clarified with you experts.
Pressure Vessel handbook by Eugene F.Megyesy, Eleventh Edition - Example calculations for the design of saddles, Page 93, S4(Circumferential Stress) value is -18,279 Psi,
but in the Thirteenth Edition - Page 93, S4 value is 20,000...
Hi Guys,
In my current project for Indirect heaters, I would like to calculate the Thermal expansion of the tubes of size 30" OD with the design temperature of 300 Deg F which runs for 52' in length. I took the linear co-efficient of expansion as 8.30E-05 for carbon steel pipes and was able to...
Hi All,
In my current project for Amine vessel, a carbon shell(SA 516 70N) has to be Weld overlayed with one layer of SS309L and a second layer of SS317L with 5/32" Thk. It has to be welded with SS316L cleats. PWHT is necessary.
My idea is to weld a Poison pad to the shell, then weldoverlay...
Hi all,
The Heat Exchanger has a design pressure of 1100 Psig and design temp of 150 F with Flange rating of Class 600. The design temp is now changed to 300 F (Design press & others remaining the same) and the calculation was done supporting this value including the name plate change. My...
