Hose clamps, also known as pipe clamps, pipe clamps, clamps, are used for fastening between soft and hard pipe connections, and are widely used in automobiles, industrial machinery, petroleum, chemical, pharmaceutical, food, winemaking, sewage treatment, purification and dust removal, ventilation systems and other industries. The materials mainly include carbon steel, stainless steel 200 series, 300 series, 400 series, etc. According to the type, there are mainly American throat clamps, German throat hoops, single-ear stepless throat hoops, T-shaped throat hoops, etc. The following mainly introduces the characteristics and functions of these types of throat hoops

1. American throat clamp, also known as conventional throat clamp, is a widely used universal throat clamp

Features: The rectangular hole groove on the steel belt provides a more powerful and precise bite, and the torque is larger than that of the German hose clamp; The disadvantage is that there is a dead angle under the worm, which is easy to leak

Application: American throat hoops are widely used, mainly including the automotive industry (air intake system, radiator hose, heater hose connection, turbocharging, diesel particulate filter, exhaust gas circulation system and other pipe fittings connection), fire protection, railway, white goods, agriculture, maritime, medical and food industries

2. The main difference between the German hose and the American hose is that it is non-perforated, and the non-perforated and flanged design can protect the hose surface from damage

Features: balanced torque, uniform pressure, can provide stable and safe fastening effect; The disadvantage is that there is a dead angle under the worm, which is easy to leak

Application: Commonly used in the automotive industry, white goods, industrial, mining, maritime and other industries, especially the connection of hoses, according to the actual application environment of the corresponding material selection of the corresponding material

3. Single-ear stepless throat clamp

Features: 360° stepless design, uniform force compression on the surface of the hose, all-round sealing guarantee, no dead angle; The cochlea design compensates for the dimensional changes caused by temperature changes of the fasteners, maintains a good fastening state for a long time, and effectively prevents leakage; Small size, simple installation, fast and safe.

Application: Widely used in hoses and plastic pipes, especially suitable for beverage, automotive, marine, motorcycle and industrial fields

Installation: This type of hose clamp installation requires a special single-ear stepless clamp operation

Put the hose sleeve with a single-ear stepless throat clamp of the appropriate size, put it into the connection device, and place the throat clamp in the correct position, then clamp the throat clamp ear with single-ear straight mouth forceps
When space does not permit, side pliers can be used instead, and they can be installed parallel to the pipe fittings
