Flexible metal hoses and bellows-type expansion joints are metal products that possess unique characteristics, being both flexible and lightweight, allowing them to respond to unpredictable movements such as shaking during earthquakes. They are designed to follow significant movements of large piping associated with earthquakes and ground subsidence, preventing damage to equipment and piping. Their effectiveness was confirmed during the 1995 Great Hanshin-Awaji Earthquake, minimizing secondary damage such as oil leaks and water outages from hazardous material piping. Our company has prepared a research report to understand and analyze these damage situations, aiming to contribute to the creation of safer lifelines. We encourage you to utilize the flexibility of flexible metal hoses and expansion joints to help prevent damage to critical equipment and piping that cannot afford to stop even for a moment.
