Class 5 Boiler Practice Exam

What must happen to the piping once it is on the job site?

1. It must be inspected only if there are visible defects

2. It must be verified by quality control

3. It can be used without inspection

4. It must be painted

The correct answer is: It must be verified by quality control

Once the piping arrives on the job site, it is essential for quality control to verify its integrity and compliance with specified standards. This process ensures that the piping meets safety regulations, industry standards, and the criteria established for the project. Verification can include checking for defects, ensuring proper dimensions, confirming material specifications, and maintaining traceability of materials. Quality control is fundamental because piping systems are critical components of plant operations, often under high pressure and temperature. If defects go undetected, they can lead to failures, leaks, or even catastrophic incidents, endangering personnel and equipment. Thus, thorough verification contributes to the overall safety and reliability of the boiler system. While visible defects are a concern, a comprehensive inspection goes beyond just observable issues, incorporating rigorous checks performed by trained personnel to ensure that the piping is suitable for service before it is put into operation.
