Description

Welding hoses. Rubber pressure hoses designed for gas cutting and gas welding are manufactured in accordance with GOST 9356-75 and are often called oxygen hoses. The main purpose of welding sleeves is the supply under pressure of working gases: acetylene, natural gas, butane, propane, oxygen, as well as liquid fuel to equipment used for gas cutting and welding.
Oxygen hoses GOST 9356-75 are produced for operation in areas with cold, temperate and tropical climates. The operating temperature range of RTI depends on their climatic version and is:
-55…+70°C – for cold and temperate climates;
-35…+70°C – for tropical.
Oxygen hoses GOST 9356-75 are divided into the following classes depending on the purpose and scope:
- class I - oxygen hoses, which are used to supply various gases or their mixtures under pressure up to 0.63 MPa (propane, butane, natural gas);
- class II - oxygen hoses designed to supply liquids under pressure up to 0.63 MPa (gasoline A-72, kerosene, white spirit or mixtures thereof);
- class III - pressure oxygen hoses, which are used exclusively for supplying oxygen under high pressure, depending on the version of the mouth, the maximum working pressure is 2.0 and 4.0 MPa.
