How it works

Press Calculate to see the weight per length, the weight of each pipe and the total.

The pipe on the hookGantry, scale and the rest of the orderNeedle: the weight of one pipeThe drawing follows your numbers as you type: the pipe's size, its wall, its length and the pieces waiting on the stack. Press Calculate and the hoist lifts one piece clear; the weight per length, each pipe and the total appear here, worked out by the tool.

23 CFR 658.17, WeightCode
Legal Information Institute (Cornell Law School)
The federal weight limits on the Interstate: 80,000 lb gross vehicle weight, lower where the bridge formula requires it. Your payload is that limit less the tractor and trailer.
