Attached find a drawing of the column and ladder, the question is regarding the construction of the ladder, spacing between rungs, width, etc. that needs to be considered. Construction under USA OSHA code will be good enough.
I wanted to know if someone has a copy of A14.3 and could send it to...
Vessel will be installed in Mexico, total vessel height is 37ft but ladder will be in the top section only (there is already structure for the rest)
8ft ladder and there is a 1/2 platform, another 8ft and there is another 1/2 platform, 7ft more and another platform.
Total ladder height is 26ft
Dear all,
while designing a fixed ladder for a distillation column, I´ve seen a reference in the pressure vessel handbook of ANSI A14.3 but only one page is shown, does anyone have a copy that could facilitate me or know where I could download a copy of the entire standard?
Thanks a lot
When designing a torispherical head, the thickness can be calculated according to UG-32 (e) with specific values for "L" and "r", but in Appendix 1-4 (d) comes the general thickness equation for any given value for L and r.
When I used equation in UG-32 with L=D and r=0.06D I had a thickness...
I am considering 3 20" access manways for the 18 trays, one below first tray second above 9th tray and last one above tray 18.
Do you think 20" is adecuate? is there a standard size for access manways? and is there a recomended distance between each manway?
The existing column will be replaced with a new one, my doubt is if I should weld it in site or have it manufactured in one piece and use a crane. Application has fouling tendency and has around 3500mg/L of fine suspended solids therefore periodic cleaning and maintenance will be done to the...
