PVC lay flat hose is a kind of watering tool. Although it is similar to metal pipe fittings, there are still some differences in some details. The main differences are as follows:
The difference between metal fittings is that the structure and shape of metal fittings are basically the same. Aluminum and aluminium alloys are widely used in the material of metal fittings. PVC lay flat hose can be folded and put away when it is not used. PVC lay flat hose is not restricted by geographical scope. The metal tube is usually drawn into thin-walled tube by drawing process. Its head is usually conical and conical, and its sealing form is often spiral. It is also used for irrigation. Metal pipes are easy to oxidize and rust in long-term contact with liquids, and deform in varying degrees. Moreover, the cost is much higher than that of PVC lay flat hose.
Secondly, PVC lay flat hose is a kind of macromolecule material. High elasticity at room temperature is the characteristic of rubber material, which is not available in any other material. Therefore, rubber is also called elastomer. The performance of high elastic materials is that they have large elastic deformation under external force. And PVC lay flat hose is not rubber, it should belong to plastic. Plastics are generally hard, rubber is generally soft, in addition to PVC soft rubber. It’s because PVC soft rubber feels like rubber, but it’s not rubber at all.
