The difference between Germany type hose clamp and American type hose clamp

The German style hose clamp tightening force is greater than that of the American hose clamp. The belt of the German throat clamp is cold-extruded to generate a concave and convex rack thread, because it is integrated, so the tensile resistance of this rack and pinion thread is very large. On the other hand, the hoop belt of the American hose clamp is transparent, and the force surface is only a small slash on the top of the hoop belt, and the force surface is this small slash, which shows that its tensile ability is far less than the integrated hoop belt, so the German those clamp has a greater torque resistance than the American hose clamp.

The same material and specifications, German hose clamp tightening force is greater than the American style, these two types of throat hoop have their own advantages and disadvantages, German clamp can be used for the demand tightening force is greater than the American clamp on the tube, so it may not be very clear, in the hose clamp several types, in the same specification size of their tightening force are: Tiger clamp > European hose clamp > wire hose clamp > German hose clamp > American hose clamp > British hose clamp

The tightening force of the clamp is compared to the ranking, there is no type of clamp is good, only the right one, when the fastening force demand is greater than the American clamp, and smaller than the wire clamp, you can choose the German clamp!

Comparison of the characteristics of German clamp and American clamp:

1. The thread on the steel belt of American clamp is perforated, while the German style is ancient concave;

2. The width of the american steel belt is 12.7mm, the small american is 8mm, (equal to 27 is small american, the other is large american), and the german is 9mm and 12mm;

3. The hexagonal of the screw head of the american clamp is 8mm, and the german style is 7mm;

Comparison of the advantages and disadvantages of German clamp and American clamp: 

The price of American clamp is lower than that of German clamp, and in the process of use, because the hoop belt of the German clamp is not a permeable structure, there is soil splashing on the German clamp, the screw of the German clamp is difficult to loosen, and the American clamp is not affected.
