Reinforced rubber hoses for compressed air：
This standard specifies the requirements of fabric reinforced rubber hoses with a maximum working pressure of 2.5MPa and an operating temperature range of -40 to + 70 degrees.
Hose type and category:
The seven types of air compressor hose and two categories are specified as follows:
A) Type:
Type 1: Maximum working pressure of 1.0MPa for general industrial air hose;
– Type 2: Maximum working pressure of 1.0MPa for heavy construction air hose;
– Type 3: The maximum working pressure of 1.0MPa with good oil resistance of the heavy construction of the air hose;
— 4: the maximum working pressure of 1.6MPa heavy construction air hose;
— 5: the maximum working pressure of 1.6 0.6 type with a good oil resistance of the heavy construction of the air hose;
— 6: the maximum working pressure of 2.5MPa heavy construction air hose;
— 7: the maximum working pressure of 2.5MPa with good oil Performance of heavy construction air hose;
B) Category —
Class A: Hose Operating temperature range: -25 ~ +70 benefits;
Class B:Hose operating temperature range: -40 ~ +70 benefits round structure and materials
The hose shall have the following composition:
– rubber lining;
– the use of any appropriate technology to lay one or more layers of natural or synthetic fabrics;
– – rubber outer coating.
The inner and outer cladding should have a uniform thickness, concentricity conforms to the specified minimum thickness, and should not have holes, trachoma and other defects.
