Question 1 of 27070

According to Coast Guard Regulations, flexible hoses used as supply and return lines to hydraulic system components, must have __________.

🔍 Key Concepts

• Hydraulic system safety margins between working pressure and bursting pressure • Difference between marking/labeling requirements and design/strength requirements • How Coast Guard regulations treat flexible hose failure risk in high-pressure systems

💭 Think About

• Ask yourself: Does simply stamping the working pressure on fittings by itself prevent hose failure, or is there usually a safety factor built into the hose design? • Think about typical industry practice: For high‑pressure hydraulic hoses, is the regulation generally focused more on labeling, or on how strong the hose must be compared to the system’s maximum working pressure? • Consider what would happen if the hose were only just strong enough for the stated working pressure with no margin—would that likely meet Coast Guard expectations for safety at sea?

✅ Before You Answer

• Verify what 46 CFR says about the required safety factor (ratio between bursting pressure and maximum working pressure) for hydraulic hoses. • Check whether Coast Guard rules explicitly require markings on end fittings, or whether the critical requirement is the minimum bursting pressure relative to working pressure. • Confirm that the correct choice directly addresses preventing hose rupture under worst‑case pressure spikes, not just identification or material type.

an inner tube constructed of seamless reinforced polyester braid

a designed bursting pressure of at least four times the maximum working pressure of the system
