In general, the pipe clamp is used to firmly fix a pipe to a building or a machine, and to support various types of pipes such as a high pressure pipe, a gas pipe, a hydraulic pipe, a steam pipe, and the like to transfer a high pressure fluid at predetermined intervals. It is installed to cope with the external environment such as earthquake, vibration and so on to firmly support the pipe.

Among these clamps, pipe clamps, which are particularly applied to an air conditioner, are mainly installed inside or outside a building, and serve to fix a duct that guides the flow of air.

In general, ducts used for air conditioning are rectangular or elliptical in cross section, but are generally used in the form of circular cylindrical tubes, and the movement of heat caused by the temperature of the air flowing in the duct is different from the surrounding temperature. In order to prevent this, the insulation may be wound around the duct.

As a material, galvanized iron is usually used, but sometimes vinyl chloride or glass fiber is also used.

In order to form an air circulation passage using the duct, a plurality of ducts are combined and connected, in particular, both ends of the two ducts must be coupled by force, and at this time, a gap between the two ends is connected so that air, heat, and gas are not leaked out. The outer peripheral surface of the seam is tightened by a coupling means such as a clamp to be stably coupled.

By the way, when looking at the structure of a general clamp, both sides are opened or retracted around the hinge portion of the center is configured in such a way to fasten the bolt against both ends.
