Question 1 of 27070

When new piping sections have been fabricated for installation in a hydraulic system, prior to installation the piping should be __________.

🔍 Key Concepts

• Cleanliness requirements for hydraulic systems and why contamination is dangerous • Standard pressure testing practices for new piping before it is put into service • Differences between chemical cleaning (pickling) and detergent/water-based cleaning and when each is appropriate

💭 Think About

• Think about what type of contamination causes the most damage in hydraulic systems and how it is usually removed before installation. • Consider whether water, chemicals, or pressure testing might themselves introduce problems into a hydraulic system if not handled correctly. • Ask which of the listed procedures are commonly required together as part of a pre-installation process, and which might be used only in specific circumstances.

✅ Before You Answer

• Verify which methods are standard practice for hydraulic piping versus those more common for other types of piping (e.g., fuel, seawater, or steam). • Check whether exposing new hydraulic piping to water-based cleaning is normally recommended or avoided. • Consider if a hydrostatic test at only 100% of maximum working pressure matches typical testing requirements (compare with usual test percentages).
