摘要： 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 (p) of the reinforcing layer (12) in all of the plurality of reinforcing layers (12) is 90% or more and less than 96%.

摘要： Provided is a method for predicting the remaining life of a hose and a method for diagnosing the deterioration level of a hose that can be easily performed without breaking the hose. The disclosure includes: a testing step of performing a hose bending test; and a predicting step of predicting the remaining life of a hose subject to prediction, wherein during the hose bending test, either a value of an external force required to displace a hose portion in a direction of the external force by a predetermined displacement amount, or a value of a displacement amount in a direction of the external force of the hose portion when the external force of a predetermined magnitude is exerted on the hose portion is measured, and the measured value is obtained as the test result.

摘要： A method and system for easily predicting a remaining lifetime of a hose are provided. A hose remaining lifetime prediction method and a hose remaining lifetime prediction system, for predicting a remaining lifetime of a hose 1 in use, include obtaining in advance, for a hose of the same type, relationship between use time of an inner tubular rubber layer 11 at a reference temperature and a physical property value of rubber forming the inner tubular rubber layer 11, generating a thermal degradation model for the inner tubular rubber layer 11, calculating, for the hose 1 in use, reference temperature use time being use time of the inner tubular rubber layer 11 at the reference temperature until a time of the prediction, and predicting the remaining lifetime of the hose 1 in use, based on comparison between the reference temperature use time and the thermal degradation model.
