Flexible Gas Line
Flexible metal hose
Hydroformed hoses yields a very clean product. Standard cleaning procedure includes degreasing and rinse. Hoses are 100% tested and leak checked.
Optional cleaning methords are
- Oxygen clean
- Ultrasonic clean
When select a flexible metal hose, consider the below 4 variables.
Temperature
As temperature increases, the hose's working pressure decreases.To figure out the actual working pressure at a particular temperature, multiply the pressure by the temperature factor in the table.
Dynamic Pressure
Pulsating, surge or shock pressure can inflict severe damage on a hose.For pulsating pressure, the working pressure should be de-rated by 1/2 For shock pressure, the working pressure should be de-rated by 1/6
Flexibility
Bend radius should not be less than the rated radius
Chemical Compatibility
Both hose and braid must be compatible with the media that folws through the hose.Refer to NACE (National Asoc of Corrosion Engineers) for information
