What method permanently supports a pipe in a pipe rack?

• A. With straps
• B. With shoes
• C. With U-bolts
• D. With welds

Answer: (B)

In a pipe rack, permanent support for a pipe comes from pipe shoes. The shoe cradles the pipe and is fixed to the rack, distributing the load over a broader area and preventing the pipe from rolling or shifting as it expands, contracts, or vibrates. This creates a stable, long‑lasting seat for the pipe while keeping it removable if needed. Straps can loosen over time, and U-bolts can bite into the pipe and fail with vibration, while welding the pipe to the rack makes future removal or maintenance impractical. So, using shoes provides a reliable, durable, and serviceable permanent support.
