The inner wall types of rubber industrial hoses
On the market, there are many transparent hoses. Such as PVC clear hose, PVC steel wire hose and silicone hose. Besides, there is another hose which is also clear. That is PU steel wire duct hose. This PU hose is also a PU duct hose. In fact, many people can not distinguish which is a PU duct hose and which is a steel wire reinforced PVC hose. Because they look the same with each other. Both of these flexible plastic hose has a tube and a steel wire. However, they are quite different from each other. Then next, let me show you them.
First of all, the material of steel wire reinforced PVC hose and PU duct is different
PVC steel wire hose adopts PVC as the raw material. But PU duct is made from polyurethane.
The temp resistance is not the same
PVC hose can work at max 65℃. Because it will soften if it exceeds the temp range. But PU duct hose can work at max 90℃. Thus it will be suitable for more apps.
Abrasion resistant
PU is more abrasion resistant. Thus it can transfer abrasive materials such as gravel, sand and grain. PVC reinforced hose can also resist abrasion. But it is not as good as PU hose.
PU flexible ducting hose is more flexible.
With the same size and thickness, PU duct will be more soft. While PVC hose is harder. Because there are many additives in the flexible PVC hose. For example, the plastizer. It is to make the PVC hose pipe more soft. But some apps such as food process has strict requirements on it. Thus PVC duct hose is not suitable for food. But PU hose can be used in food process. Because PU is nontoxic and odorless.
We can see that steel wire reinforced PVC hose and PU steel wire hose are quite different. Then you can test the above properties to distinguish them. If you are still not sure, just contact Orientflex. We will offer you the best solution.
