What should be used to hold the pipe when setting up two 40-foot joints of 16-inch STD WT pipe?

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

Answer: (A)

When you’re setting up two long pipe joints, you need supports that both hold the pipe securely and let you move it smoothly to align the ends for welding. Four-legged roller top jacks provide a sturdy platform with a roller surface, so the pipe can roll gently as you position it. This rolling capability is essential for bringing the joints into line without jamming or having to lift the entire length. The height is adjustable, which helps you bring the pipe ends to the same level and keep the seam aligned during tack-welding or final welding. The four legs spread the load, giving stable support on studio floors and tolerating minor surface unevenness—critical when dealing with a heavy 16-inch STD WT pipe over a 40-foot span.

Pipe stands without rollers don’t offer the rolling control you need for precise alignment. Wooden blocks can shift or crush under weight and aren’t reliable or safe for long, heavy sections. Hydraulic jacks can lift but don’t give a continuous rolling contact surface to align the joints. So the rolling-top, four-legged jacks are the best fit for this setup.
