The building seismic isolation metal pipelines is mainly designed for pipeline systems with certain pressure within buildings. It is usually made of materials such as stainless steel and is intended to provide displacement compensation for water supply, fire protection and other pipelines during seismic conditions. The structural design of this product focuses on balancing the strength and flexibility of the material to accommodate multiple directions of displacement and oscillation. Before leaving the factory, this product usually undergoes a series of performance tests, including pressure resistance, sealing and fatigue performance, etc., in order to help maintain the integrity and sealing state of the pipeline connection when the building shakes. Its connection methods mostly adopt flanges or clamps, which are convenient for on-site installation and construction.
