PE PA and PP corrugated hose look the same but quite different from each other
PU air duct hose is suitable for liquid transportation under general working pressure in the fields of industry, agriculture, food, medicine, civil engineering, fishery, aquaculture, garden irrigation, etc. The reason why the PU air duct is so popular is that it has a strong advantage and has won the support of consumers. Now let’s take a look at the advantages of PU ducts?
1. From the overall point of view, the appearance of PU air pipe is beautiful, the bending radius of the hose is relatively small, and it does not contain any poisonous gas and taste. Compared with the ordinary tube, it has stronger impact resistance, fatigue resistance, light and convenient to carry, can be used flexibly, and its weight is less than 75% of the rubber hose;
2. The oil resistance is very strong, 15-20 times higher than that of natural rubber;
3. Good wear resistance, exceeding 30 times the wear resistance of natural rubber;
4. The PU air duct has strong aging resistance, is not prone to corrosion, and has a long service life, which is more than 5 times the aging resistance of ordinary natural rubber.
5. In addition, it has a very strong tear resistance and is not easy to break; and the damping performance is good, the inner wall is very smooth, the liquid resistance is not large, and the hydraulic loss is small.
Based on the above five advantages, everyone must know the reason why PU vent pipes are popular. After all, only high-quality products will stand in the market for a long time.
