Q: What is the most critical installation mistake to avoid with a metal flex hose?
A: Avoid twisting the hose during assembly; use two wrenches on the end fittings to prevent torsional stress.
Q: How should a metal flex hose be supported or routed to ensure durability?
A: Install so the flex occurs in one plane only, avoid sharp bends near end fittings, and provide proper support so the hose carries no pipe load.
Q: Why is bend radius so important in metal flex hose installations?
A: Exceeding the minimum bend radius causes fatigue, braid wear and early failure of the hose.
Q: What should be inspected regularly on a metal flex hose assembly in service?
A: Check for frayed braid, dents or flattened corrugations, leaks around fittings, and ensure no external abrasion is occurring.
Q: What storage or handling practices prolong the life of a flexible metal hose?
A: Store dry in a loosely coiled state, keep it away from welding spatter or corrosive fumes, and avoid stacking heavy objects on it.
