Abstract

Multi-layer metal bellows flexible hose is a widely used compensating element in the chemical piping system, playing a role in displacement compensation, vibration isolation and noise reduction. The three-dimensional finite element model of double layer metal bellows flexible hose with wire braid was established in ANSYS, strength and stiffness analysis is conducted, and the stress and strain distribution of double layer bellows are obtained. It was proved that the wire braid can strengthen the metal hose by comparing the performance of bellows with or without wire braid. It was found through this analysis that the structural parameters of the metal hose designed by traditional methods are too conservative. The results provide a reference for the design and application of multi-layer metal bellows flexible hose.
