When new piping sections have been fabricated for installation in a hydraulic system, prior to installation the piping should be _______________.
AI Explanation
The correct answer is B) descaled by using a pickling solution.
Prior to installation, new piping sections for a hydraulic system should be descaled using a pickling solution. This is a crucial step to ensure the integrity and performance of the hydraulic system. Pickling removes any scale, rust, or other contaminants from the internal surfaces of the piping, which could otherwise interfere with the proper functioning of the hydraulic components.
The other options, while potentially beneficial in other contexts, are not the primary requirement for new piping sections before installation in a hydraulic system. Cleaning with a water-based detergent (A) may help remove surface dirt, but does not address the need for descaling. Hydrostatic testing (C) is important, but typically performed after installation, not as a pre-installation requirement.
