At least he searched, I guess. :dunno:

Pipe 1 1/2 Sch 40 (A-36)-
Weight - 3.631 lbs/ft
Grade A - Tensile strength - 48,000 psi, yield strength - 30,000 psi
Grade B - Tensile strength - 60,000 psi, yield strength - 35,000 psi
DOM 1.500 X .140 wall (1018) -
Weight - 1.769 lb/ft
Tensile strength - 80,000 psi, yield strength - 70,000 psi
HREW 1.500 X .140 wall (1020) -
Weight - 1.769 lb/ft
Tensile strength - 50,000 psi, yield strength - 36,000 psi
As you can see: 1) tube is about 1/2 the weight, 2) pipe will bend easier than DOM, 3) DOM has the highest tensile and yield strengths, and 4) HREW is about the same strenght as pipe.

Bender said:Pipe is cheap beacause it has a greater variance in tolerance and composition. Tube is more because it has tighter tolerances and composition requirements.
