PRESSURE RUBBER HOSES WITH TEXTILE REINFORCEMENT GOST-10362-76.
This standard applies to pressure rubber hoses with textile reinforcement, used as flexible pipelines for supplying air, inert gases and liquids under pressure, operable in areas with a temperate and tropical climate at temperatures from minus 50 °Ñ up to plus 90 °Ñ,
in regions with a cold climate at temperatures from minus 60 °Ñ to plus 90 °Ñ.
This standard does not apply to a hose for gas welding and cutting of metals, a power hydraulic system of combine harvesters, food industry and diving equipment.

HOSES must be operable in working environments at a temperature range:
|
Working environments
|
Working environment temperature, °Ñ
|
|
Aviation gasoline according to GOST 1012 and automobile gasoline according to GOST 2084
|
from - 50 to + 70
|
|
Jet fuels according to GOST 10227 and diesel fuels according to GOST 305
|
from - 50 to + 70
|
|
Petroleum based oils
|
up to +100
|
|
Liquid lubricants
|
from - 50 to + 100
|
|
Lubricant grease in accordance with GOST 1033
|
|
Air
|
from - 50 to + 60
|
|
Gases are neutral (inert)
|
|
Water
|
up to + 100, short-term up to + 120
|
|
Low -temperature cooling liquid according to GOST 28084
|
from - 60 to + 120
|
|
Weak solutions of inorganic acids, alkalis (up to 20% concentration), except for nitric acid
|
from - 50 to + 50
|
The minimum bending radius of the hose during operation must correspond to
the standards:
|
Inner diameter, mm
|
Minimum bend radius
|
|
up to 25
|
8 inner diameters
|
|
from 25 to 50
|
10 inner diameters
|
|
from 50 to 63
|
15 inner diameters
|
|
from 63 to 100
|
20 inner diameters
|
The change in the outer diameter of the hose at the minimum bending radius should not be more than 10% of the actual diameter of the hose.
GAMMA-percentage
the resource of the hose, subject to the requirements of this standard, should be at a normal resource:
20 thousand km - for vehicle components and assemblies
5000 engine hours - for units and assemblies of tractors up to 01.01.92
ã.
Since 01/01/92, the resource of hoses for units and assemblies of tractors with γ = 0,9 – 8000 engine hours.
In order to ensure tightness and operability of the hose, when tightening with clamps, the wall deformation is taken within 15% - 30%, when embedded in couplings –
25% - 45%.
It is allowed to grind the outer rubber layer at the ends of the sleeves at a length of 25 – 30 mm,
the entire stripped part of the hose must be clamped by the sleeve.
It is NOT ALLOWED to reinforce the sleeve after it has been at a temperature below 0°Ñ
without preliminary exposure at a temperature of 15°C to 25°C for 24 hours.
