What is A PVC Hose
PVC hose stands for polyvinyl chloride hose. It is a PVC flexible hose made from a synthetic thermoplastic polymer. These hoses are ideal for transporting fluids, gases, and solid materials in various industries. There are multiple layers in the construction of PVC hose. The inner layer is typically made of PVC, and the reinforced layer can be made of other materials. The inner layer provides a smooth passage for the flow of substances. On the other hand, a reinforced layer adds increased strength and pressure resistance. Finally, the outer layer protects the hose from external factors like abrasion and chemicals.
The manufacturing process involves four primary steps. First, the PVC compounding step mixes the PVC resins with plasticizers, stabilizers, and other additives. Second, the extrusion process melts and forms a continuous tube. The process cools the PVC hose to solidify and stabilize its shape. Third, the reinforcement addition process adds necessary reinforcement layers. It may involve braiding, spiraling, or wrapping the reinforcement materials around the inner tube. Finally, the manufacturing process ends with curing and finishing steps.
