There is no specific national standard for American hose clamps, and the currently used standards refer to industry standards.
According to the width of the hose hoop steel belt, American hose hoops are divided into small American style, middle American style and large American style. The width of the small American style is 8mm, the width of the middle American style is 10mm, and the width of the large American style is 12.7mm.
The outer diameter d=16, the bandwidth is 8mm, and the American hose clamp made of stainless steel SUS304 is marked as:
SUS304 American hose clamp 10-16
At present, the most common hose clamps on the market are mostly stainless steel hose clamps, and the material is stainless steel SUS304.
The throat clamp solves the dead angle that occurs when the existing technology is used for the connection of small-diameter soft and hard pipes, resulting in the leakage of liquid and gas. The throat clamp adopts an open inner and outer ring structure and is fastened with bolts. It is widely used in automobiles, tractors, forklifts, It is an ideal connecting fastener for locomotives, ships, mines, petroleum, chemical industry, pharmaceuticals, agriculture and other water, oil, gas, dust, etc.
American-style hose clamps are generally used in vehicles, bulldozers, cranes and ships. The biggest feature of American-style hose clamps is that the steel belt thread has holes. In these transportation tools, friction is the first consideration. Because the occlusal groove of the American hose hoop steel belt is a through-hole type, and the teeth of the screw are embedded, it is more powerful when locked and the bite is accurate. The straps are easy to break. Therefore, the tensile performance of American hose clamps is not as good as that of German hose clamps.
German-style hose clamps have great resistance to twisting and pressure, and can achieve a very tight fastening effect. German-style hose clamps are used in maintenance, decoration or sewer maintenance details. The German-style hose clamp has superior performance, its own friction is very small, and it has a wide range of applications. When connecting some special parts with high grades or high requirements, only the German-style hose clamp can meet the requirements. It can be tightly locked, and it is also beautiful and delicate. . Widely used in vehicles and ships, chemical petroleum, medicine, agriculture and mining and other fields.
