The bending radius of the PVC hose is usually 5 to 10 times its inner diameter. Specifically, PVC hoses with different inner diameters have different recommended bending radius ranges:
For a PVC hose with an inner diameter of 10 mm, the bending radius is recommended to be between 50 mm and 100 mm.
For a PVC hose with an inner diameter of 25 mm, the bending radius is recommended to be between 125 mm and 250 mm.
For a PVC hose with an inner diameter of 50 mm, the bending radius is recommended to be between 250 mm and 500 mm.
For a PVC hose with an inner diameter of 100 mm, the bending radius is recommended to be between 500 mm and 1000 mm.
These data are for reference only, and the specific values should be based on the technical parameters provided by the manufacturer. Factors affecting the bending radius of PVC hoses include wall thickness, wire spacing, and material hardness. Hoses with thicker walls generally have larger bending radii because they are more difficult to bend; hoses with smaller wire spacing are more flexible when bending because the gap between the wires allows for greater deformation; harder PVC materials also require larger bending radius.
In practical applications, try to avoid bending the hose below the minimum bending radius to prevent damage to the hose. In the case of a small bending radius, you can consider using devices such as protective sleeves or reinforcement rings to reduce the risk of wear and damage.
