CALCULATION OF S.S.SHEETS, CIRCLE, PIPES, ROUND BAR & FLAT BAR


Weight of S.S. Sheets & Plates
Length ( Mtrs ) X Width ( Mtrs ) X Thick ( MM ) X 8 = Wt. Per PC
Length ( fit ) X Width ( Mtrs ) X Thick ( mm ) X ¾ = Wt. Per PC

Weight of S.S. Circle
Dia ( mm ) X Dia (mm ) X Thick ( mm ) / 160 = Gms. Per PC
Dia ( mm ) X Dia (mm ) X Thick ( mm ) X 0.00000063 = Kg. Per PC.

Weight of S.S. Pipe
O.D. ( mm ) – W Thick ( mm ) X W.Thick ( mm ) X 0.0248 = Wt. Per Mtr.
O.D. ( mm ) – W Thick ( mm ) X W.Thick ( mm ) X 0.00758 = Wt. Per Mtr.

Weight of S.S. Round Bar
Dia ( mm ) X Dia (mm ) X 0.00623 = Wt. Per. Mtr.
Dia ( mm ) X Dia (mm ) X 0.0019 = Wt. Per. Feet.

Weight of S.S. Square Bar
Dia ( mm ) X Dia ( mm ) X 0.00788 = Wt. Per. Mtr
Dia ( mm ) X Dia ( mm ) X 0.0024 = Wt.Per. Feet.

Weight of S.S. Hexagonal Bar
Dia ( mm ) X Dia ( mm ) X 0.00680 = Wt. Per.Mtr
Width ( mm ) X Dia ( mm ) X 0.002072 = Wt. Per Feet

Weight of S.S. Flate Bar
Width (mm ) X Thick ( mm ) X 0.00798 = Wt.Per Mtr.
Width (mm ) X Thick ( mm ) X 0.00243 = Wt.Per Feet.

Weight of Brass Pipe / Copper Pipe
O.D. ( mm ) – Thick ( mm ) X Thick (mm ) X 0.0260 = Wt. Per Mtr.

Weight of Lead Pipe
O.D. ( mm ) – Wt ( mm ) X Wt ( mm ) X 0.0345 = Wt. Per Mtr.

Weight of Aluminium Pipe
O.D. ( mm ) – Thick ( mm ) X Thick ( mm ) X 0.0083 = Wt.Per. Mtr.

Weight of Aluminium Sheet
Length ( Mtr ) X Width ( Mtr ) X Thick ( mm ) X 2.69 = Wt.Per PC

Weight of Conversion of Mtr to Feet
Wt of 1 Mtr. 3.2808 = Wt.Per Feet.

Barlow’s Formula for calculating bursting pressure
P = 2ST/Dort – DP/2S or S – DP/2t or D = 2st/p
P = Bursting Pressure P. si.
S = Tensile Strength of tube.
T = Well Thickness ( In Inches )
D = Outside diameter ( In Inches )
