Calculating Pipes Weight

A weight calculating formula for steel pipes


If the outside diameter and the wall thickness of a steel pipe is known, the weight per foot can be expressed as:
m = 10.68 (do - tw) tw         (1)
where
m = weight per foot (lbs/ft)
do = outside diameter (inches)
tw = wall thickness (inches)

Example - Weight of 4" Schedule 40 Steel Pipe

The outside diameter (do) of 4" Schedule 40 Steel Pipe is 4.500 inches. The wall thickness is 0.237 inches. The weight per foot can be calculated using (1) as:
m = 10.68 ((4.500 in) - (0.237 in)) (0.237 in)
= 10.79 lbs/ft

Schedule Terminology

An introduction to pipes and the schedule terminology


For all pipe sizes the outside diameter (O.D.) remains relatively constant. The variations in wall thickness affects only the inside diameter (I.D.).
A schedule number indicates the approximate value of
Sch. = 1000 P/S
where
P = service pressure (psi)
S = allowable stress (psi)
The higher the schedule number is, the thicker the pipe is. Since the outside diameter of each pipe size is standardized, a particular nominal pipe size will have different inside pipe diameter depending on the schedule specified.

Welded and Seamless Wrought Steel Pipe

To distinguish different weights of pipe, it is common to use the Schedule terminology from ANSI/ASME B36.10 Welded and Seamless Wrought Steel Pipe:
  • Light Wall
  • Schedule 10 (Sch/10, S/10)
  • Schedule 20 (Sch/20, S/20)
  • Schedule 30 (Sch/30, S/30)
  • Schedule 40 (Sch/40, S/40)
  • Standard Weight (ST, Std, STD)
  • Schedule 60 (Sch/60, S/60)
  • Extra Strong (Extra Heavy, EH, XH, XS)
  • Schedule 80 (Sch/80, S/80)
  • Schedule 100 (Sch/100, S/100)
  • Schedule 120 (Sch/120, S/120)
  • Schedule 140 (Sch/140, S/140)
  • Schedule 160 (Sch/160, S/160)
  • Double Extra Strong (Double extra heavy, XXH, XXS)
Note that many of the schedules are identical in certain sizes.

Stainless Steel Pipe

For stainless steel pipes thru 12-inch, schedule numbers from Schedule 5S to schedule 80S are used as published in ANSI/ASME 36.19M Stainless Steel Pipe.
  • Schedule 5S (Sch/5S, S/5S)
  • Schedule 10S (Sch/10S, S/10S)
  • Schedule 40S (Sch/40S, S/40S)
  • Schedule 80S (Sch/80S, S/80S)

ASME/ANSI B36.10/19: pipe sizes, diameters, wall thickness, working pressures

The steel pipe data chart below (download .pdf) can be used to find pipe sizes, diameters, wall thickness, working pressures and more The chart is based on ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe and ASME/ANSI B36.19 Stainless Steel Pipe.

Regardless of schedule number, pipes of a particular size all have the same outside diameter (not withstanding manufacturing tolerances). As the schedule number increases, the wall thickness increases, and the actual bore is reduced. For example:
  • A 4 inches (100 mm) Schedule 40 pipe has an outside diameter of 4.500 inches (114.30 mm), a wall thickness of 0.237 inches (6.02 mm), giving a bore of 4.026 inches (102.26 mm)
  • A 4 inches (100 mm) Schedule 80 pipe has an outside diameter of 4.500 inches ( 114.30 mm), a wall thickness of 0.337 inches (8.56 mm), giving a bore of 3.826 inches (97.18 mm)

STD, XS and XXS

To distinguish different weights of pipe, three long standing traditional designations are used:
  • standard wall - STD
  • extra strong wall - XS
  • double extra strong wall - XXS
The last two designations are sometimes referred to as extra heavy wall (XH), and double extra heavy wall (XXH).
