I’m the online reception in EverFlex. Sometimes clients call us that “I want a PVC steel wire hose. The temperature should be 150℃. While the pressure should be 5 bar”. If I was a fresh, client may bring me to a wrong way. However, I am not that innocent. In fact, client just call like this. Some new clients even call silicone hose and PU hose as PVC hose. Moreover, they also call highly transparent PTFE hose as PVC hose. Because they look almost the same. Thus it’s hard to distinguish if not work in relevant industry.
On such occasion, let me introduce you steel wire hose. As the structure, it can be smooth and spiral types. Smooth type is suitable for liquid and high pressure usages. But spiral steel wire hose is more light and flexible. Thus it’s better for ventilation and dust suction.
General smooth steel wire hoses are PVC and PU.
It is transparent and it works at -20℃-70℃, shortly to 80℃.
- Transparent and nontoxic
- Acid and alkali resistant
- Pressure and oil resistant
- Excellent chemical resistance
- Small bending radius
- Liquid, gas and powder transfer in industry and petroleum.
- Water deliver in agriculture and dust deliver
PU steel wire hose
It’s the best hose for oil and particle deliver at high pressure. Generally, it acts as the support in irrigation, mine, food and sandblast. It can transfer water, oil, particle and gas from -40℃-90℃.
- Soft, light with excellent elasticity
- Corrosion and hydrolysis resistant
- Nontoxic and odourless
- Remains original shape in vacuum state
- Remains flexible in extremely low temperature
- Very long service life
We can see neither PVC nor PU can transfer 120℃ medium. Thus client may ask for another hose. Above are the differences between PVC and PU steel wire hose. But if you still feel confused, just contact EverFlex.
