Someone hello ! there, anyone who kows, how to calculate Horizontial storage tank thickness, or are there any applied rule for thickness criterial

Thank you all for the help.

Dear ALL Does anyone have experience for chemical Acid cleaning in Air cooled condenser inside tube. Tube thickness is very thin(mild carbon steel(ASTM A618), 1.6mm) where to welded with Tube sheet. So I'm concerned about effect on tube failure after Acid cleaning.

Dear ALL During posting this issue, there was some changes, the correct one is follows. 1. Post from 26 Nov "after trimming BFP Pump 4th to 8th as much as 2%.." 2. Post of 26th Nov "and discharge head was decreased to 50kg/cm^2 from 60kg/cm^2".

Dear ALL Against my previous post, after trimming BFP Pump 4th to 8th as much as 2%, we are now facing another problems of Bleeding flowrate that decreased to 60m^3/h from 70m^3/h and discharge head to 50kg/cm^2 from 60kg/cm^2, Are there any idea for explanation why this bleeding flowrate was...

Dear Artisi Pls refer to attached file for for this clarification. http://files.engineering.com/getfile.aspx?folder=22063005-0258-4f9a-95ad-03941b9c43ac&file=pump-TDH.pdf

Dear sir, Demiwater pump have 8m of suction head below storage tank, and pump discharge head is of 80m, in this case, is this suction head(8m) have to be included in a total head calculation of pump as to 88m.

Dear ALL As I said previous, for results of Impeller trimming. Let me say what is going on after trimming. Actually, this 8 stage BFP pump impeller was trimmed about 2% diameter from 4th impeller to last 8th impeller except but 1st to 3rd. the results of this trimming was little bit good...

Dear Edstainless As I know, there is limited Blower as named Ring Blower, Roots Blower Anybody can compare capacity and Noise for each other.

I got a realized that refinement is much more important than technology.

Dear velkoki CFR value is one of Fluid Dynamic force, please refer to following the example calculation. Ma at MCR 400,000 Kgf/hr Mb at Blowing out 450,000 Kgf/hr Va at MCR 0.2346 m^3/kgf Vb at Blowing out 0.2346 m^3/kgf CFR @ Mass Flow =(Mb/Ma)^2*(Vb/Va)=1.27 Generally, CFR...

Dear ALL Ar there any recommendation for how to reduce noise of roots blower, in there too much noise during pre-commensioning test in Coal power plant. Are there another type of blower noise is less than roots type.

Let me give you more clarification on piping noise, I posted this issue regarding for only Restriction orifice and Noise firstly. And then I tried to reduce noise with change of Orifice in a Single double type (Installed 2 place, Multi hole double type(7 holes one plate installed 2 places) with...

Dear ALL I have one solution to reduce this noise due to thin thickness of S.S. pipe. The way is to install Bending Stiffener ring on piping in a 3 times Diameter(3*D) of Distance, This will reduce vibration and Noise to have reinforcement of pipe's thin thickness.

Dear Bimr, As I mentioned previous, we tried to install multi-stage orifice as well as Double stage also.

Dear ALL I guess that piping noise is nothing regard to cavitation at downstream of Orifice becasue water temperature is below 30oC and may not be flushing under this condition, Even if not condensated water. When I calculate this fluid Dynamic force, it could be noise through thin wall pipe...

Dear Saplanti This Demi-Pump have a inlet head from Demi Tank (App.18m), so we don't need to consider cavitation due to NPSHa.

Dear gerhardl This pump is parallel installed for 3 sets, noise is nearly same for each single set.

Dear ALL This paper has been prepared by PES-ENG(http://www.pes21.com) for the guidance in decision of required thickness for piping design based on related CODE rule and industrial practice. Especially, this paper would like to indicate additional consideration in stage of minimum required...

Dear Bimr No piping insulation is doned for Demi-water piping.
