Concrete pipe loaded crosswise generally _________.

Special Circumstances: Securing Pipe with an Inside Diameter Up to 1.143 mm (45 in) 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. Note: This pipe diameter of 1.143 m (45 in) is simply a convenient breaking point between "medium" and "large" diameter pipe. Note: 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. At least one tiedown through the rear pipe of the bottom tier must run forward at an angle not more than 45 with the horizontal when viewed from the side of the vehicle, when ever practical.
