During assembly, pipe should be examined how to detect contaminants?

• A. Externally
• B. Internally to detect and remove contaminants
• C. By X-ray
• D. By pressure test

Answer: (B)

The important practice is to inspect the inside of the pipe to detect and remove contaminants. Debris, rust, or foreign matter can be present inside pipes from manufacturing, handling, or prior use, and if missed, this material can clog nozzles or restrict flow when the system operates. External checks won’t reveal such internal contamination, and while a pressure test can show leaks and strength, it doesn’t identify or remove internal debris. X-ray isn’t a practical routine method for cleaning and inspecting piping during assembly. So, examining the interior—then flushing or cleaning out any contaminants—best ensures the system will perform properly.
