Short answer
The choice between braided and spiral wire hose is made according to the pressure and impulse requirements of the application and the installation conditions. Neither construction is unconditionally superior to the other. The actual technical data of the candidates at the same size and their compatible connection systems should be compared.
Technical explanation
Wire braided and spiral reinforced products are different structural families; standards such as ISO 1436 and ISO 3862 address them in separate scopes. However, the standard family alone does not decide the application. Pressure class, temperature, fluid, external factors and movement conditions are defined separately. One side of the comparison may offer higher pressure, the other a tighter installation. The weight given to these properties should come from the actual machine need.
Topic-specific checkpoints
| Item | Description |
|---|---|
| Braided candidate | Pressure, impulse and geometry data for the relevant model/size. |
| Spiral candidate | The same data fields against the same service condition. |
| Common requirement | Fluid, temperature, safe installation and verified assembly. |
| Decision rationale | Which requirement is met by which document. |
How is it assessed in practice?
In the decision table, first make the mandatory conditions elimination criteria. Do not keep a candidate that fails the pressure or fluid suitability on the list because its flexibility is good. Compare the remaining candidates on outside diameter, weight, bending, ease of assembly and service continuity. The old hose being multi-layered may not mean the same is mandatory; but a reduction decision is also not made without measurement and verification. Clearly mark the structural change in the equivalence file. Do not finalize the braid/spiral choice before the actual pressure, movement and installation priorities are defined.
Original editorial recommendation; not a clause of a standard.
Frequently asked questions
Is switching from spiral to braided always a drop in performance?
Such a conclusion cannot be given without product and service data. It must be documented that the required performance is met; a decision on improvement or degradation should not be made by looking at the construction name.
