- Two measures for saving energy by preventing hose kinking and collapsing
- (1) Allow slack in piping: By ensuring hoses are of a sufficient length to allow some slack, pressure loss can be reduced, enabling stable operation over the long term.
- (2) Choose hoses that are resistant to kinking and collapsing: Hoses with special designs and reinforcing materials reduce pressure loss by being resistant to kinking and collapsing, resulting in higher levels of energy savings.
Why does hose kinking and collapsing prevent energy savings?
Here’s a question from Hose Adviser PRO.
Hoses used in factory facilities are essential components for efficiently carrying fluids. However, pressure loss will occur if hoses are kinked or collapsed.Why do kinked or collapsed hoses cause pressure loss?
Select from among A, B and C below.
A. Kinking and collapsing reduce the inner diameter of the hose, restricting fluid flow.
B. Kinked portions accelerate fluid flow, in turn increasing pressure.
C. Kinking and collapsing disrupt the pressure distribution inside the hose, causing the fluid to flow irregularly.
The correct answer is A. Kinking and collapsing reduce the inner diameter of the hose, restricting fluid flow.
For example, even if there are no problems when a hose is straight, if routed in a tight space where the minimum bending radius is exceeded or if unable to withstand the weight of the hose itself or the fluid being carried, the inner diameter may become smaller at the bends, leading to pressure loss. This results in increased energy consumption and reduces energy savings.

Energy saving measures — 1. Allow some slack in the hose piping
One main cause of hose kinking and collapsing is hoses piped in tight spaces being bent beyond their minimum bending radius. It is important to ensure piping is long enough to prevent it from kinking or collapsing. Allowing slack in the hose ensures a clear flow path for the fluid, reducing pressure loss.
Energy saving measures — 2. Select hoses resistant to kinking and collapsing
Although there may be no problems when piping is initially installed, over time, the weight of the hose or fluid being carried can cause the hose to kink or collapse, potentially obstructing fluid flow.
To prevent this, it is effective to use hoses with a design that is resistant to kinking and collapsing. For example, hoses that incorporate metal wires or resin coils or hoses that use a special PET resin as a reinforcing material have a structure that is both highly pressure-resistant and kink-resistant, which reduces pressure loss.
Toyox offers a variety of shape-retaining hoses capable of preventing kinking and collapsing. Please check the product list below to see which product suits your usage conditions.

Also, some braid type hoses are less prone to kinking and collapsing than others due to the braiding method of the reinforcement thread or thread material used. This product is also suitable for piping in tight spaces.

Energy is essential to our lives. Even in factories and production sites, many tasks are carried out using electricity and gas, and energy savings are becoming increasingly important. However, there may be some people who are unsure about how to save energy. Here, Hose Adviser PRO will describe tips on how energy can be saved by preventing kinking and collapsing. Because even minor worksite improvements can often save energy, we urge you to read about the measures introduced here.
