Advantages of Flexible Metal Hoses

                  

Modes of Movements

Suitable for wide temperature range (-270° to 700°C)

Static Installations

Compensates for thermal expansion/contractionin the piping system.

Where the flexible hose is used to connect misaligned pipes and remain in static position.

High physical strength.

Occasional Flexing 

Fire resistant.

Where the hose is required to flex occasionally, such as manually operated equipment.

Moisture resistant.

Constant Flexing 

Longer life. 

When the hose is required to flex continuously, usually in moving machinery.

Good corrosion characteristics. 

Vibration 

Resistant to abrasion, penetration & damage. 

High frequency, low amplitude movement e.g. On a compressor.

Connects misaligned rigid piping, absorbs or dampens vibration and similar equipment. 

A flexible & quick option for rigid piping in difficult locations.

The above values are applicable for FLEX-IT Braided Hose & Assemblies only. * The above pressure ratings are for fluid and ambient temperature of 20°C. For higher temperatures apply corrosion factors as per Table II. * The above data for 250mm and 300mm N.B. can be supplied on request. * The burst pressure is 4 times the maximum working pressure. * The above technical data is subject to change on account of design improvement.
