AI Technical Summary
Existing corrugated metal hoses are prone to breakage under the complex operating conditions of railway vehicles due to bending forces, affecting the normal use and safety of the pipeline and posing a risk of media leakage.
A main metal wire is embedded in the corrugated pipe body. The extension of the main metal wire extends into the pipe joint and forms a connection space with the inner wall of the pipe body, which enhances the resistance to bending and fracture. The stress is dispersed by the spiral structure, and the auxiliary metal wire and multi-layer rubber reinforcement design are used to improve the structural stability and flexibility.
It significantly enhances the bending and fracture resistance of corrugated metal hoses, improves reliability and service life under complex working conditions, reduces the risk of media leakage, extends the service life of hoses, and improves system safety and production efficiency.
