How to select rubber hose?
1. Internal working medium of rubber hose: compressed air, water, engine oil, speed changing box oil, steam, etc.
2. Working temperature: including working medium temperature, surronding environment temperature.
3. Working pressure: normal operating pressure, max working pressure; to decide pulsating pressure and pulsating frequency, etc.
4. Working environment: if there is bending of rubber hose? What's the bending degree? If there is friction with car body?
5. Special requirements: including insulating property, electrical conductivity, flame retardant property, color appearance, etc

Nickel based alloys are very useful materials for the manufacture of high quality tubing products. One of the key reasons is that they offer excellent corrosion resistance in both aqueous and high temperature applications.
In addition to their high melting points and resistance to oxidation and corrosion, nickel alloys are very ductile. They can be electroplated and are easily welded, making them suitable for use in industries where very high and low temperatures come into play.
Nickel alloys steel tube are excellent for heat exchangers in the chemical processing and nuclear industries. Nickel Alloy Steel Tube are used in steam generator tubing in the nuclear power industry, in high-temperature aircraft systems, and in oil and gas extraction programmes where corrosion, pressure and temperature resistant tubing is required. Nickel alloy steel tube corrosion resistance also makes them useful in desalination equipment.
