Concrete pipe with an inside diameter up to 1.143 m (45 in) can form a complete single tier on a typical flatbed vehicle. Larger pipe often can only be carried as a partial tier.
This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe. At least one tiedown through the front pipe of the bottom tier must run rearward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical. Load bell pipe on one tier so that the bells alternate on opposite sides of the vehicle. If possible, the ends of consecutive pipe must be staggered within the allowable width. If the ends cannot be staggered, they must be aligned.
