Abstract
To provide a laminated hose capable of achieving both pressure-resistant performance and oscillating durability performance. The laminated hose (1) comprises a plurality of reinforcing layers (12) laminated to the hose body (11), and each of the plurality of reinforcing layers (12) includes a reinforcing wire (13). A wire density (ρ) of the reinforcing layer (12) in all of the plurality of reinforcing layers (12) is 90% or more and less than 96%.
Claims13
A laminated hose comprising a hose body and a plurality of reinforcing layers laminated on the outer circumferential side of the hose body, and each of the plurality of reinforcing layers includes a reinforcing wire, wherein
- a wire density of the reinforcing layer in all of the plurality of reinforcing layers is 90% or more and less than 96%, and
- a wire bending density of the reinforcing layer in each of the plurality of reinforcing layers does not exceed 100% when the laminated hose is bent at a bending radius determined by the specifications of the laminated hose, the wire bending density being the wire density of the reinforcing layer when the laminated hose is bent and viewed from an inner circumference in a radial direction of bending to an outer circumference and the bending radius being a radius of curvature generated at the innermost circumference of the laminated hose in the radial direction of bending when the laminated hose is bent.
A laminated hose comprising a hose body and a plurality of reinforcing layers laminated on the outer circumferential side of the hose body, and each of the plurality of reinforcing layers includes a reinforcing wire, wherein
- a wire density of the reinforcing layer in all of the plurality of reinforcing layers is 90% or more and less than 95%, and
- a wire bending density of the reinforcing layer in each of the plurality of reinforcing layers does not exceed 100% when the laminated hose is bent at a bending radius determined by the specifications of the laminated hose, the wire bending density being the wire density of the reinforcing layer when the laminated hose is bent and viewed from an inner circumference in a radial direction of bending to an outer circumference and the bending radius being a radius of curvature generated at the innermost circumference of the laminated hose in the radial direction of bending when the laminated hose is bent.
