PE PA and PP corrugated hose look the same but quite different from each other
High pressure hydraulic hose is to transfer hydraulic oils. It is also known as hydraulic oil hose, flexible hydraulic hose, high pressure hose, etc. It is generally divided into steel wire braided hydraulic hose and steel wire wound hydraulic hose.
The hydraulic hose consists of a inner rubber, a reinforce and a cover. The inner tube can bear higher pressure. Besides, it can prevent the reinforce from corrosion. While the cover protects the steel wire from damage. Then the reinforce supports the hose and makes it high pressure resistant.
High pressure hydraulic hose medium temperature
For oil, it is -40 to 100℃. While for air, it is -30 to 50℃. But for water, it is 0 to 80℃.
High pressure hose media
The mediums can be water, gas and oil.
Standards for high pressure hydraulic hose
The most common standards of such hose are DIN, SAE, ISO and GB/T.
The standards of steel wire braided hydraulic hose are DIN EN 853 and SAE J517. For example, EN 853 2SN. While the standards for steel wire spiral hoses are DIN EN 856 and SAE J517. For example, SAE 100 R1.
Hydraulic hose fittings
Hydraulic hose has a wide range of sizes. While in order to fit the hose, there are many kinds of high pressure hose fittings. While the typical fittings include connector, joint and ferrule. As for the material, they can be stainless steel and brass. While for the types, it can be thread and male/female.
There is a special hydraulic hose. Because it adopts the PTFE but rubber as the inner tube. That is SAE 100 R14 PTFE lined hose. PTFE hose has excellent wear resistance. Besides, it can resist corrosion. Thus it can transfer corrosive mediums.
