Which of the following is not included in piping checks?

• A. Testing safety devices
• B. Inspection of pipe welds
• C. Verification of pipe insulation
• D. Pressure testing of lines

Answer: (A)

Piping checks focus on the piping system itself—the joints, insulation, and the ability of the lines to hold pressure. Inspecting pipe welds ensures joints are sound and free of defects that could cause leaks or failure. Verifying pipe insulation confirms the system’s thermal performance and energy efficiency. Pressure testing of lines checks for leaks and guarantees the pipe can withstand its intended operating pressure.

Testing safety devices belongs to a separate domain, because protective components like relief valves, pressure sensors, and shutdown devices are evaluated for their functional performance and safety response outside of the piping-check scope. They require different criteria and procedures.

Therefore, testing safety devices is not included in piping checks, making it the best choice.
