Characteristics and applications of American, German and English throat hoops

09/15/2023

In the fields of automobile, industrial machinery, petroleum, chemical industry, agriculture, pharmaceutical, valves, etc., the hose band for soft and hard pipe connection is widely used, and the hose band is mainly divided into three categories: American hose band, German hose band, British hose band.Today, I will talk to you about the characteristics and application fields of these three laryngeal hoops.

American collar

The American hose band is the most widely used, so it is also called the conventional hose band, which is more common. The American hose band is divided into small American hose band and large American hose band whose bandwidth is 12.7mm and 14.2mm respectively.

The characteristic of the American throat band is that the rectangular hole groove on the steel belt can provide a more powerful and accurate bite, and the torque is larger than the German throat band. The deficiency of the American throat band is that the worm is dead under the hole, which is easy to produce leakage.

In automotive (air intake system, radiator hose, heater hose connection, turbocharger, diesel particle filter, exhaust gas circulation system and other pipe connection), railway, home appliances, agriculture, fire protection, Marine. In food, medical and other fields, American laryngeal hoops are widely used.

German throat hoop

The difference between the German hose hoop and the American hose hoop is that the German hose hoop is non-perforated, using a non-perforated and flanged design, which can protect the surface of the hose from damage.

The German type throat hoop is characterized by its balanced torque and uniform pressure, which can provide stable and safe fastening effect, and its deficiency is the same as the American throat hoop, which is prone to leakage under the dead Angle dry worm.

German hose hoops are mostly used in automotive, home appliances, mining, industry, maritime and other fields of hose connection.

English hose

The free torque and overall torque of the British hose hoop are relatively high, its edge is smooth and will not damage the hose, can be reused, and its fastening strength is high and the price is cheap.It is widely used in automobile, mining, forklift, ship, locomotive, petroleum, chemical agriculture, pharmaceutical, tractor and other fields.

In general, the steel belt of the American hose band is threaded with holes, while the German hose band is convex and convex, without perforation. The bandwidths of American, German and British hoses are different, but they can be directly applied to connections between pipes within 30mm.
