Metal Hose

We supply annular metal hose in many different sizes, alloys and configurations.  Our “Matchless” metal hose is ideal for absorbing vibration, misalignment, piping expansion or contraction, and equipment motion.

Braiding enables use at high pressures and attenuates vibration.  Each annular corrugation is a separate element engineered to impart optimal flexibility for each size of hose we offer

**Other hose alloys may be required for special service applications.  An open pitch configuration will provide for limited flexibility.

Metal Hose Terminology

Annular- A hose profile that is designed so each convolution is a separate circle or ring.

 

Braid– Woven wire cover placed over hose which prevents elongation of the hose and permits higher working pressure.

 

Close Pitch– More corrugation per foot, which renders the longest fatigue life and minimum bend radius.

 

Constant Flexing Bend Radius– The minimum radius to which a hose can be repeatedly bent and render satisfactory flexure life.

 

Constant Motion– Motion that occurs on a regular cyclic basis at a constant travel.

 

Fittings– Part attached to the ends of metal hose so that it can be connected to other components, such as flanges, unions , nipples, etc.

 

Flow Velocity– When the flow velocity exceeds 75 ft./second liquid, 150 ft./ second gas in braid hose, a flexible metal liner should be used.

 

Intermittent Motion– Motion that occurs on a regular or irregular cyclic basis.

 

Maximum Test Pressure– Maximum pressure hose assembly should be subject to for testing purposes. Based on 150% of the maximum working pressure.

 

Media– Conveyant in a hose assembly such as gases, liquid, etc.

 

Operating Conditions– Temperature, pressure, media, motion and application involved.

 

Random Motion– Uncontrolled motion that occurs usually from manual handling of hose.

 

Rated Burst Pressure– Pressure at which hose can be expected to fail. Braid will normally fail before core burst.

 

Safety Factor– Difference between working pressure and rated burst pressure.

 

Shock or Pulsating Pressure– Shock, pulsating or surge pressure can cause premature failure of hose.

 

Static Bend– Minimum center bend radius to which flexible metal hose may be bent for installation.

 

Vibration– High frequency, low amplitude motion.

 

Working Temperature– Temperature to which hose will be subjected during operation.
