When Does Stainless Flex Hose Become Mandatory?

In industrial hydraulic and pneumatic systems, hose selection is critical for the safety and continuity of the system. In some special conditions where standard rubber or thermoplastic hoses are insufficient, the use of stainless flex hoses becomes technically mandatory. In this article, we discuss from a technical perspective in which cases stainless flex hose is not a choice but a necessity.

  1. High-Temperature Environments

Standard hydraulic hoses can generally  operate in the range of -40 °C to +100 / +120 °C. However;

  • Furnace systems
  • Foundries
  • Steam lines
  • Exhaust and peri-engine applications

The temperature  can rise to 200 °C and above. In such applications, rubber hoses become stiff, cracked, or fail in a short period.

Stainless flex hoses become mandatory in these environments due to their high-temperature resistant structure.

 

  1. Very High Pressure Requirement

As the pressure increases in hydraulic systems, the risk of hose bursting also increases. Specifically:

  • Systems with high impact pressures
  • Pressure spikes
  • Circuits operating under continuous high pressure

For standard hoses do not offer a sufficient safety coefficient.

Stainless steel braided flex hoses become a mandatory solution at this point thanks to their high burst pressure and long-lasting structure.

 

  1. Chemical and Corrosive Fluids

Apart from hydraulic oil in some industrial applications;

  • Chemical liquids
  • Acidic or basic fluids
  • Solvents
  • Sea water

There are aggressive environments such as. These fluids can quickly degrade the interior surface of rubber hoses.

Stainless flex hose becomes technically mandatory in such applications thanks to its chemical resistance.

 

  1. Intense Vibration and Mechanical Strain

In mobile hydraulic systems, machine chassis or vibrating equipment, hoses are continuously:

  • Twisting
  • Oscillating
  • Mechanical stress

It is exposed. This causes premature wear on standard hoses.

Stainless flex hoses provide long-term safe use thanks to their vibration damping ability and metal braid structure.

 

  1. Fire Safety and Risk Areas

The risk of fire is high in areas such as petrochemical plants, refineries, and power plants. Rubber hoses may be flammable.

Stainless flex hose is considered mandatory equipment in such facilities thanks to its resistance to fire  .

 

  1. Long Service Life and Maintenance Cost

Hose replacement in some applications:

  • Difficult
  • Costly
  • Causing a system downtime

It is a process. In such cases, longer-lasting solutions are preferred.

Stainless flex hose reduces the total maintenance cost thanks to its long service life and becomes a necessity rather than a choice.

Conclusion: Choice or Necessity?

If one or more of the following conditions are present, the use of stainless flex hose becomes mandatory:

  • High temperature
  • Very high pressure
  • Chemical fluids
  • Intense vibration
  • Risk of fire
  • Long life expectancy

As Hidroman,  we maximize system safety and performance with application-specific stainless flex hose solutions.
