Standard & Range For Hydraulic Hose Used In Mine
Standard of hydraulic hose used in mine has a specific requirement on six sucked cord types wire reinforced hydraulic hose and hydraulic hose assembly (inner tube size is from 5mm to 51mm), which are applicable to mineral oil, aqueous oil, oil and water miscible liquid, ethylene glycol and water etc. normal hydraulic fluid.
Working temperature for wire braided mining hydraulic hose and four layers wire braided mining hydraulic hose is -40 degree Celsius to +100 degree Celsius;
In severe rugged environment, with high temperature resistant, high pressure resistant, working temperature for R15 type hydraulic hose is -40 degree Celsius to +130 degree Celsius;
If over than those working temperature range, using life of hydraulic hose will be greatly reduce.
Generally using type:
1. Double wire braided: mainly use hydraulic hose with 10 mm and 16 mm inner tube
2. Four layers wire spiral: mainly used hydraulic hose with 10 mm, 13 mm, 25 mm and 32 mm inner tube
3. Six or multi wire spiral: mainly used hydraulic hose with 25 mm and 32 mm inner tube
