Instructions for Selection, Installation and Mounting
The life time of metal hose will increase when following instructions
1.Select the proper hose type
2.Select the right fittings
3.Do not overbend the hose
4.Do not torque a corrugated metal hose
5.Avoid scratching over rough surface
6.Avoid exposure to weld or grinding splatters
When you select a metal hose the following considerations
should be made:
- Pressure capacity:
capacity of metal hoses decreases at higher temperatures.
- Temperature influence:
Correct the working
pressure with the temperature correction factors which are indicated
in this catalog.
may require a heavier pressure class hose than the pressure capacity
Whenever possible select at least one swivel fittings or a floating
flange. This avoids torsions problems during mounting.
Avoid overbending, specially close to the fittings. Install the
hose in its most natural position, free of kinds and sharp bends.
Torsion can give dramatic consequences on the life of a corrugated
metal hose. Torsion occurs when the movements are not in the same
plane as the fittings. Use two keys when swivel nuts. Note: Stripwound
hose can absorb some torsion.
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.
Weld or grind splatters may lead to corrosion of the stainless steel
parts. Use a heat proof shield during welding or grinding in the
proximity of metal hoses.
