Stainless steel corrugated hose is a flexible and pressure resistant hose in liquid transfer. It’s mainly to compensate the displacement among pipes or machines. Besides, it can absorb the vibration and reduce the shock and noise. It is light in weight and flexible. What[‘s more, it resists corrosion and temp. This time, let’s talk about the factors when install it.
First is the stiffness
The load value that makes corrugated hose or other elastic element displace is the stiffness. Generally, it shows as “K”. However, if the elasticity is nonlinear, the stiffness will not be a constant. On such occasion, it will change as the load increase. The designed stiffness of elastic element is called nominal stiffness. But there is error between the measured and practical one. Especially for the nonlinear elements.
However, nominal represent which point is to consider. Generally, don’t use the designed value, but the tested one. Besides, each element of stainless steel corrugated hose is different on the stiffness. Thus to guarantee the usage, the stiffness has a range. While it should be within 5%.
Common problems for install
1. When do the welding work, protect the stainless steel hose well. Because it may hurt the hose and even burn it through. Besides, the hose should be straight without any distortion.
2. You can’t bend the stainless steel hose along with the end. Besides, make sure the medium will not corrode the hose. Meanwhile, the CI content should be less than 25PPM.
3. Install the hose based on the drawing bu your willing. Moreover, keep the hose away from machines to avoid damage.
4. Never clean the hose with available CI.
These are the points that you should pay attention to. And hope this piece can help you. If you have any questions about the stainless steel hose, feel free to contact OrientFlex. We focus on hoses since 2006. And now, it is a famous brand in the world.
