Weights

"WEIGHTS" --- PIPE AND TANK WEIGHT CALCULATION PROGRAM

Program Description:

"WEIGHTS" is a spreadsheet program written in MS-Excel for the purpose of calculating the weights of pipes and

tanks or vessels. Specifically, the weight of pipes either empty or full of contents, with/without insulation, and

with/without ice buildup is determined. The volume and weight of tanks or vessels of various top/bottom or

end configuations is determined.

This program is a workbook consisting of seven (7) worksheets, described as follows:

Worksheet Name DescriptionDoc This documentation sheet

STD Pipe Wt's Calculate weights of standard weight steel pipes

XS Pipe Wt's Calculate weights of extra-strong weight steel pipes

XXS Pipe Wt's Calculate weights of double-extra strong weight steel pipes

Pipe Rack Level Wt. Calculate total weight of steel pipes on a pipe rack level

Vert. Tank Vol. & Wt. Calculate volume and weight of a vertical cylindrical tank

Horiz. Tank Vol. & Wt. Calculate volume and weight of a horizontal cylindrical tank

Program Assumptions and Limitations:

1. "STD Pipe Wt's" worksheet assumes use of standard weight (STD) steel pipe for diameters from 1/2" up

through 48".

2. "XS Pipe Wt's" worksheet assumes use of extra strong (XS) steel pipe for diameters from 1/2" up through 48".

3. "XXS Pipe Wt's" worksheet assumes use of double-extra strong (XXS) steel pipe for diameters from 1/2" up

through 12".

4. "Pipe Rack Level Wt." worksheet permits use of STD, XS, and XXS steel pipes.

5. References used for pipe OD and ID properties are as follows:

a. AISC Manual of Steel Construction, 13th Edition CD Database for STD pipes from 1/2" through 12" dia.

b. ITT Grinnell Pipe Hanger and Engineering Manual for STD pipes from 14" through 36" dia.

c. AISC Manual of Steel Construction, 13th Edition CD Database for XS pipes from 1/2" through 12" dia.

d. Crane Technical Paper No. 410, "Flow of Fluids through Valves, Fittings, and Pipe" (1991) for XS pipes

from 14" through 36" dia.

e. AISC Manual of Steel Construction, 13th Edition CD Database for XXS pipes from 2" through 8" dia.

f. Crane Technical Paper No. 410, "Flow of Fluids through Valves, Fittings, and Pipe" (1991) for XXS pipes

from 1/2" through 1-1/2" dia. and 10" through 12" dia.

g. Website www.allsteelpipe.com for STD and XXS pipes of 42" and 48" dia.

6. Worksheet for Vert. Tank Volume & Weight assumes vertical cylindrical tank, and permits use of various top

and bottom configuations. Tops may be either flat, spherical, or elliptical. Bottoms may be either flat,

elliptical, spherical, or conical.

7. Worksheet for Horiz. Tank Volume & Weight assumes vertical horizontal tank, and permits use of various end

configuations. Left and right ends may be either flat, elliptical, or spherical.

8. Worksheet for Vert. Tank Volume & Weight assumes wall thickness of center, cylindrical section is same as

for top and bottom. Where top and/or bottom thickness are not the same as center, cylindrical section, the

user may account for the difference by including an estimated correction weight (+/-) in the Misc. Weight input.

9. Worksheet for Horiz. Tank Volume & Weight assumes wall thickness of center, cylindrical section is same as

for both ends. Where end thicknesses are not the same as center, cylindrical section, the user may account

for the difference by including an estimated correction weight (+/-) in the Misc. Weight input.

10. This program contains several “comment boxes” which contain a wide variety of information including

explanations of input or output items, equations used, data tables, etc. (Note: presence of a “comment box”

is denoted by a “red triangle” in the upper right-hand corner of a cell. Merely move the mouse pointer to the

desired cell to view the contents of that particular "comment box".)

Select pipe diameter from pick boxes below. For no pipe to be selected, the user may select a "blank" from the pick box options. Otherwise, the user should clear contents of any unused input cells by highlighting the cells to be cleared, right-clicking on PC mouse, and selecting "Clear Contents". DO NOT clear the contents of any unused input cells with a "blank space" (spacebar).

B22

Input total number of duplicated pipes with same given diameter, specific gravity, insulation and ice criteria.

C22

For reference, unit weight of water = 62.4 pcf, having a specific gravity = 1.0. For air or steam lines, input specific gravity = 0.

D22

Typical insulation densities are: calcium silicate = 12.5 pcf foamglass = 9.0 pcf fiberglass = 7.0 pcf polyurethane = 2.2 pcf

F22

For pipes with exterior (outside) exposure subjected to freezing rain, an ice buildup should be considered. For reference, density of ice = 56.0 pcf, having a specific gravity = 0.90.

H47

Total uniform distributed piping load = total piping weight per level / rack width.
