What is meant by visual test in piping?

A visual test in piping refers to a non-destructive examination method used to assess the integrity and condition of pipes and piping systems. This test involves a thorough inspection of the surfaces for any visible defects, such as cracks, corrosion, weld quality, or misalignments. It is often the first step in identifying potential issues and ensuring compliance with safety and industry standards. Visual testing is typically conducted using the naked eye or with the aid of tools like magnifying glasses or borescopes for hard-to-reach areas.
