The inner wall types of rubber industrial hoses
PVC corrugated hose is a common material in construction. It’s made from PVC resin and mould by extrude. While it’s mainly to protect wires with in 2000V in industry. However, it becomes popular in house decoration and water system recent years. Next let me show you the great properties.
Flame retardant
PVC corrugated hose absorbs high quality raw material. And all the properties meet the relevant standards.It can extinguish within 30 seconds away from fire. Besides, it can bear AC2000V and 50Hz alternating current without any break.
Excellent cold bending property
Insert a bend spring into the hose and you can bend the hose to the need shape. While you don’t have to do any other treatment.
Resist high pressure
PVC heavy duty corrugated hose can bear 120N. Thus in can stay in the concrete without any destroy.
Moisture and corrosion proof
All the connect points stick with PVC adhesive. It can effectively prevent the water and moisture. Besides, it will not rusted by acid, alkali and salt.
We know PE is another great material. While PE corrugated hose is also popular. But in reality, PVC hose is more popular than PE. Why cause that? In fact, there are mainly 2 reasons.
First, PVC corrugated hose is more safe than PE
The test shows that the safety factor of PVC is much better than PE. That means the use intensity and security is higher than PE. For example, the PVC hose wall thickness is thin than PE hose with the same diameter. Because the material intensity at normal temperature is not good as PVC. It have no choice to enhance the intensity but increase the thickness.
Another is that PVC corrugated hose is much flexible
PVC hose can bend freely. But PE can just bend within the limit. While the flexibility is not as good as PVC. Thus it’s harder to operate. Besides, it looks not that beautiful than PVC.
