Clamp is a necessary part for hoses. A proper clamp not just affect the normal use. But also avoid the problems during use. For example, leakage. Next, I will provide you some points.
Effective clamp solution depends on fitting. Thus you have to consider these questions for the best seal property.
1. Barb joint is good for sealing in general. But it not suitable for think wall or low pressure uses.
2. Joint size should make the hose a little stretch. Because you can’t clamp it tightly with a over large one. But a small joint may be easy to connect or release the hose.
3. However, the joint should has enough strength to bear the compress force from clamp. Besides, only the hose absorbs strong and elastic material you can choose a heavy duty fitting.
How diameter affect the axial thrust
The pressure gathers inside the hose and cause axial thrust. Then it force the hose break from the joint. Therefore, one of the main functions of clamp is to against the axial thrust. Then fix the hose in place.
As for the axial thrust, it’s measured by the pressure inside the hose and the diameter. For example, The axial thrust of DN200 hose is 100 times than the DN20. Thus I suggest you use the heavy duty in large pressure and large size hose. Otherwise your hose can’t work for long time.
You have to tighten the it to get the best performance. We offer you the largest torque value. While the larger the input torque is, the larger the force will be. However, this can’t compare the related strength. Because other factors like screw and belt width will also work.
