The bending radius of a hose is the distance from the center of the hose to the most distant point of the bend. This is important because it affects the flexibility and strength of the hose. If the bending radius is too small, it can damage the hose, while a bending radius that is too large can make the hose too difficult to handle.
The recommended bending radius for a hose depends on a variety of factors, including the material of the hose, the size of the hose and the pressure to which it will be exposed. In general, hoses made from more flexible materials, such as rubber, have a larger bend radius than hoses made from more rigid materials, such as steel. Smaller hoses also have a smaller bending radius compared to larger hoses, and hoses that are subjected to higher pressures have a smaller bending radius than hoses that are subjected to lower pressures.
It’s important to check the recommended bending radius for the hose before bending it. If you bend the hose at a radius that is too small, you can damage the hose by creating cracks, punctures or leaks. In some cases, bending a hose to a radius that is too small can even lead to the breaking of the hose.
Euroflex knows the importance of this factor, so to avoid damaging a hose should be bent in the radius that we recommend in the product data sheet. Likewise, here are some tips to bend a hose without damaging it:
• Use your hands to bend the hose. Do not use tools, such as pliers or scissors, to bend it.
• Bend the hose slowly and carefully. Don't force the hose.
• Bend the hose to a radius at least equal to the recommended radius.
• Avoid bending the hose at sharp angles.
• If you need to bend the hose at a sharp angle, do it gradually, in several steps.
• After bending the hose, check for damage. If you see any damage, replace the hose.
By following these tips, you can help ensure the proper functioning of your hoses.
The bending radius of a hose can be calculated using the following formula:
Bending radius = (2 * Pi * Diameter) / Curve angle
Where:
• Diameter is the diameter of the hose in millimeters.
• Angle of the curve is the angle of the curve in degrees.
For example, if a hose has a diameter of 10 millimeters and is bent at a 90-degree angle, the bending radius will be 157.08 millimeters.
It’s important to note that the bending radius is a minimum value. To avoid damaging the hose, it’s important to bend the hose to a radius that is at least equal to the bending radius recommended by the manufacturer. If you are unsure of the recommended bending radius for a hose, you can find the information in its corresponding data sheet.
