Which device is used to hold two 40-foot joints of pipe during setup?

• A. Pipe stands
• B. 4 legged roller top jacks
• C. Wooden cribbing
• D. Hydraulic jacks

Answer: (B)

Positioning long pipe sections during setup requires a surface that can support them securely while still allowing you to move and align the pieces. A four-legged roller top jack provides a stable base and a rolling top surface, so you can rest the two 40-foot joints on it and roll and adjust their position as you align and tack them together. The rolling top reduces friction and makes fine adjustments easier without lifting each joint. Other options either hold pipe in a fixed, non-rolling position (pipe stands), provide a rough, non-rolling support (wooden cribbing), or focus on lifting rather than stabilizing during alignment (hydraulic jacks), none of which offer the combination of stability and rollability needed for setup.
