Application of stainless steel flexible duct to an aseismatic building

The overground and underground parts of the building are joined by vibration isolator set in the vibration isolating floor. Utilizes the stainless steel flexible duct to join pipe sections through the vibration isolating floor to keep the piping system from being damaged when the two parts of the building have horizontal displacement in earthquakes. According to construction conditions of the vibration isolating floor, adopts the direct flexible connection method for the pipes of diameter less than or equal to DN100 and the diverted flexible connection method for the rest. Presents the calculation method for choosing the flexible tubes.
