    Stainless steel corrugated hoses, installed as flexible pressure-bearing fittings in liquid conveying systems, are utilized to compensate for mutual displacement at pipeline or machinery/equipment connection points, absorb vibration energy, and effectively serve purposes such as vibration reduction and noise elimination. They boast multiple characteristics including excellent flexibility, lightweight, corrosion resistance, fatigue resistance, and high/low temperature resistance.
