HOSES FOR GAS WELDING AND METAL CUTTING GOST 9356-75



The product is used to supply pressurized gases, liquid fuels, oxygen to devices for gas welding and metal cutting.

Hoses for gas welding and metal cutting are divided into 3 classes:



I class – for the supply of acetylene, urban gas, propane, butane at a pressure of 0.63 MPa;
II class – for the supply of liquid fuels: gasoline, kerosene or mixtures thereof at a pressure of 0.63 MPa;
III class – for the supply of oxygen at a pressure of 2.0 MPa.

OPERATING TEMPERATURE:



from -35°С up to +70°С – for moderate and tropical climate
from -55°С up to +70°С – for cold climate.
Margin oxygen hoses: not less than 3P.
