INSTRUCTIONS FOR SELECTION, INSTALLING AND MOUNTING

The life time of metal will increase when proper instructions are followed

1. Select the proper hose type

2. Select the right fitting

3. Do not over bend the hose (Check technical data)

4. Do not torque a corrugated metal hose

5. Avoid scratching over rough surfaces

6. Avoid exposure to weld or grinding splatters

 

1. Hose Selection

When you select a metal hose the following considerations should be made   

     - Pressure Capacity:
     The Pressure capacity of metal hoses decreases at higher temperature.
     - Temperature influence:
     Correct the working pressure with the appropriate temperature correction factors.
     - Handling:
     Rough handling may require a heavier class hose than the pressure capacity indicates
 
2.Fitting selection
Whenever possible select at least one swivel flitting or a floating flange. This avoids torsion problems during installation.
 
3.Overbending
Avoid overbending, specially close to the fitting. Install the hose in its most natural position, free of kinks and sharp bends
 
4. Torsion
Torsion can have dramatic consequences on the life of a corrugated metal hose. Torsion occurs when the movements are not in the same plane as the fitting. Use two key when fixing swivel nuts.
Note: Strip wound hose can absorb some torsion
 
5. Scratching
The braiding is the essential part of a hose assembly to withstand the internal pressure. A damaged braid diminishes the pressure capacity of the assembly and is detrimental to its function.
 
6.Splatters
Weld or grind splatters may lead to corrosion of the stainless steel parts. use a heat proof shield (no plastic!) during welding or grinding in the proximity of metal hoses.
