Rubber hoses are used to supply acetylene, city gas, propane, butane, liquid fuel and oxygen under pressure to TEST 2 gas welding and metal cutting devices.
Rubber hoses are divided into the following groups according to the usage:
I – for feed of acetylene, town gas, propane and butane under pressure P 6,3 kgf/cm² (0.63 MPa)
II – for feed of liquid fuel: petrol A-72 in accordance with GOST 2084-77, white spirit GOST 3134-78, kerosene or their mixture under pressure P 6,3 kgf/cm² (0.63 MPa)
III – for feed of oxygen under pressure P 20 kgf/cm² (2 MPa)
The outer hose layer is black, but it’s also possible to manufacture outer layer of the following colours:
I group – red;II – yellow;III - blue
The hoses are serviceable in moderate and tropical environment at temperatures from -55°C to +70°C.
The hoses have minimum triple safety margin by hydraulic pressure break.
Special features of the hoses are strength, flexibility and resistance to attack by corrosive media.
