How much weight per foot does 30 inch diameter pipe with half inch wall thickness have?

That depends on the material of the pipe. A lead pipe would weigh more than a plastic one.
However, if you know the mass per cubic inch of the material, you can work it out, here's how you do it:
Let m = the mass of one cubic inch of the material
Let w = the total weight of the pipe
Let l = the length of the pipe in inches
then the equation you want is this:
w = lmπ(r2 - (r - 0.5)2)
Given that we want the weight per foot, we can say that "l", the length in inches, equals 12. We can also replace "r" with the outer radius of the pipe:
w = 12mπ(302 - 29.52)
w = m × 333π
w ≈ m × 1046.15
Where w is the weight of the pipe, and m is the mass of the material per cubic foot.
