Cast Iron Pipe Weight Calculator

Here, I’ll use standard nominal pipe sizes commonly used in the industry. The weights are estimated per linear foot of pipe.

Nominal Pipe Size (inches)	Weight (lbs/ft)
1/2	3.0
3/4	3.9
1	5.0
1 1/4	7.0
1 1/2	8.0
2	10.0
2 1/2	14.0
3	17.0
4	21.0
5	26.0
6	31.0
8	42.0
10	54.0
12	66.0
14	78.0
16	92.0
18	105.0
20	118.0
24	140.0

These weights are approximations and can vary depending on the specific type of cast iron, wall thickness, and manufacturing standards. For precise applications, it is advisable to refer to the specifications provided by the pipe manufacturer.
