Clamp type coupling assemblies for liquefied petroleum gas (LPG) transfer hoses
N SN EN 14422
Annotation
This European Standard specifies the dimensions, designation, materials, marking and testing requirements for a range of hose fittings which may be used with rubber/plastic hoses for the transfer of liquefied petroleum gas, LPG, in liquid or vapour phase and natural gas.
The maximum working pressure is 25 bar1).
For normal operation the working temperature range is from -30 °C up to 70 °C and for low temperature operation (LT) it is from -50 °C up to 70 °C.
The nominal size for hose fittings with internal and external threads is from DN 15 to DN 75 and for hose fittings with flanges DN 15 to DN 200.
In addition to the fittings described in this European Standard, threaded connections according to EN 14420-5 as well as hose fittings with screwed ferrules according to EN 14424 up to DN 25 for LPG could be used.
1) 1 bar = 0,1 MPa
