First, the type of rubber hose
There are many types of rubber hoses, and the common ones are as follows:
1. Ordinary rubber hose: generally used to convey liquids at room temperature, such as water, oil, gas, etc.
2. Oil-resistant rubber hose: suitable for transporting oil, diesel and other liquids, with good oil resistance.
3. Acid and alkali resistant rubber hose: suitable for conveying acid and alkaline liquids, with good corrosion resistance.
4. High temperature resistant rubber hose: suitable for conveying high temperature liquid or gas, with good high temperature resistance.
5. Low temperature resistant rubber hose: suitable for conveying low temperature liquid or gas, with good low temperature resistance.
2. List of specifications and sizes of rubber hoses
The following is a list of common rubber hose specifications and sizes:
Model Dimensions (inner diameter × wall thickness) Length
6 6×2 100
8 8×2.5 100
10 10×3 100
13 13×3.5 50
16 16×4 50
19 19×4 50
25 25×4.5 50
32 32×5 50
38 38×5.5 40
50 50×6 30
Note: The length unit in the table is meters.
3. Parameters and specifications of rubber hoses
1. Allowable working pressure: The rubber hose will withstand a certain amount of pressure when in use, and its allowable working pressure refers to the maximum pressure value that the hose can withstand under normal use conditions.
2. Burst pressure: When the rubber hose is subjected to pressure that exceeds the allowable working pressure, it may rupture, and the pressure at this time is called burst pressure.
3. Pressure resistance: When the rubber hose is under pressure, it has a certain pressure resistance, and its pressure resistance refers to the maximum pressure value that the hose can withstand under normal use conditions.
4. Temperature resistance: The rubber hose has a certain temperature resistance when it is subjected to high or low temperatures.
5. Corrosion resistance: Rubber hoses have certain corrosion resistance when they withstand corrosive liquids such as acids and alkalis.
