Why do Stainless Steel Flexible High Pressure Braided Hoses Come in Different Lengths?

Stainless steel flexible high pressure braided hoses for gas use are designed in different lengths, mainly to meet diverse application scenarios and practical needs.

1. Adaptation to Different Installation Distances

Long distances: Some applications (e.g. industrial gas distribution, laboratory equipment connections) require hoses to span long distances. Longer hoses (e.g. 10 metres or more) reduce the use of couplings and reduce the risk of leakage.

Short connections: Compact spaces (e.g. medical equipment, gas stoves) require short hoses (0.5-2 metres) to avoid tangles or redundancies, ensuring safety and aesthetics.

2. Pressure and Flow Optimisation

Length affects pressure drop: Fluid flow in a long hose creates frictional resistance, resulting in a drop in pressure. High-pressure scenarios (e.g. hydrogen storage) may require shorter hoses to maintain pressure stability.

Flow matching: Long hoses may restrict flow rates, and the appropriate length should be selected based on the type of gas (e.g., propane, oxygen) and flow requirements.

3. Safety and Compliance Requirements

Standards: Different countries/industries have strict regulations on hose lengths. For example, domestic gas hoses are usually no longer than 1.5 metres to prevent the risk of mechanical damage or deterioration.

Bend radius limitation: Excessive bending of long hoses may lead to fatigue breakage of the metal braid, and the length needs to be adjusted according to the usage environment.

4. Flexibility and Convenience

Mobile equipment needs: If welding cylinders need to be moved frequently, longer hoses (3-5 metres) provide operational flexibility; for fixed equipment, shorter hoses reduce clutter.

Installation Angle Adaptation: Different lengths can be adapted to complex pipework, avoiding twisting or stretching.

5. Cost and Material Savings

Customisation: Avoiding the waste of material caused by excessively long hoses (higher cost of stainless steel), users can choose economic lengths according to actual needs.

Transportation constraints: Extra long hoses (e.g. >20m) may be more difficult to transport, standardised lengths in segments are easier to handle.

6. Special Application Scenarios

High/low temperature environments: Extreme temperatures may cause the hose to expand and contract, so allowances should be made for length.

Vibration cushioning: vibration areas of machinery and equipment (e.g. compressor outlets) may require longer hoses to absorb vibrations.

Summary

Stainless steel flexible high pressure braided hoses are available in different lengths to balance safety, functionality, economy and compliance. Selection requires consideration of the gas type, pressure rating, installation environment and industry standards to ensure that it meets both the needs of the application and safety regulations.
