Learn MoreI'm checking some calculations of my software for the minimum thickness of a cylindrical shell. I do not understand why I get different results if I use the formula UG-27 (1) from the one that uses the Mandatory Appendix 1 (1).

Learn Moreformula: P = t X TS /R Where P is the maximum pressure, t is the wall thickness, TS is the tensile strength of the materials in the shell and R is the radius of the shell.

Learn Morethickness, (b) increase the wall thickness of the nozzle, or (c) use a combination of extra shell and nozzle thickness. The Code procedure is to relocate the removed material to an area within an effective boundary around the opening. Figure 9.1 shows the steps necessary to reinforce an opening in a pressure vessel.

Learn MoreThis method calculates boiler efficiency by using the basic efficiency formula- η=(Energy output)/(Energy input) X 100 In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred.

Learn Moreradius of thickness ratio between 10 to 500 (Bhaduri, 1984). Shell Thickness Working Equations The needed Shell thickness of pressure vessels is a function of the ultimate tensile strength of the metal at operating temperature, operating pressure, vessel diameter and welding joint efficiency (Peters et al, 2004).

Learn MoreTubes span across the length of boiler shell from the furnace side tube sheet to the channel side tube sheet. Tubes are welded to tube sheet on both the ends.Tubesheet is thick plate with multiple holes drilled in it. It has same number of holes as that of number of tubes in tube bundle.

Learn MoreHowever, if the tube is used in boiler plant, the calculation should refer to ASME BPV Code Section I Part PG 27.2.1 as following formula: t = (P D / 2 S) + 0.005D + e + Ca t = minimum required tube thickness P = maximum allowable working pressure

Learn MoreHowever, if the tube is used in boiler plant, the calculation should refer to ASME BPV Code Section I Part PG 27.2.1 as following formula: t = (P D / 2 S) + 0.005D + e + Ca t = minimum required tube thickness P = maximum allowable working pressure

Learn MoreRe: boiler shell thickness Working the equation for a cylinder under pressure I come up with 216psi with a safety factor of 5 and assuming 55000 tensile strength and .7 joint efficiency. The tube sheet will be your limiting factor on pressure.

Learn MoreI have some tube, 0.043" wall thickness, nominally 2.625 diameter I bought as 'boiler tube', without a specific project in mind. Tubal Cain's formula gives a working pressure of well over 100psi (it gives 124psi if you use 3800 as the 'working stress' at 100psi)/350fahrenheit), which seemed very high to me.

Learn MoreBoiler efficiency is a combined result of efficiencies of different components of a boiler. A boiler has many sub systems whose efficiency affects the overall boiler efficiency. Couple of efficiencies which finally decide the boiler efficiency are-Combustion efficiency; Thermal efficiency

Learn MoreRe: Boiler wall thickness You want to purchase a copy of Mark's Mechanical Engineer's Handbook. There is an extensive section on Mechanics of Materials which contains much information on cylinders and tubes containing internal pressure as on boiler drums.

Learn MoreOur nominal thickness is 20 mm, so up to 19.746 is acceptable then for the above example. The thickness dimension is also OK. So the above head dimensions are ok. Pressure Vessel Dimension Inspection - Out of Roundness of Shell: UG-80 deals with out of roundness of shell.

Learn MoreSec.VIII-1 shell formula origin 4. If you have problem with the thickness you may use higher grade material if acceptable for the process, cost and availability. Or you may offer the client alternative rule, ASME VII Div 2 which will give you less thickness but you will be forces to provide more specific calculations.
