Description

  The present invention relates to a dew condensation prevention structure suitable for piping a piping such as a copper pipe for air conditioning, a water pipe, a gas cladding pipe, etc. using a piping hanging band, and the piping hanging band comes into contact therewith. The present invention relates to a dew condensation prevention structure for piping that can prevent the thinning of a portion of the heat insulating material and eliminate various inconveniences such as dew condensation caused by the thinning.

  When a pipe such as a coated copper pipe for air conditioning is hung horizontally, a pipe suspension band as shown in Patent Document 1, for example, is used. However, a coated copper pipe for refrigerant, such as a coated copper pipe for air conditioning and a gas coated pipe, is provided with a coating layer made of a heat insulating coating material such as foamed polyethylene or foamed polyurethane on the outside of the pipe. For this reason, when the pipe is supported from the outside of the covering layer, the load of the pipe is concentrated on the portion where the suspension band for the pipe is in contact, and local compression occurs, so-called compression creep deformation occurs. As a result, the coating layer formed to a predetermined thickness is thinned, and the effect of the heat insulating coating material may be partially lost. Thus, when a part of the coating layer is thinned, various inconveniences such as dew condensation on the thinned part and a decrease in the heat retaining effect of the heat insulating coating material occur.

  In particular, when dew condensation occurs on the thinned portion, the dew condensation may drop as water droplets on the ceiling, equipment, etc., corrode the surroundings, or cause mold or the like. Therefore, conventionally, it may be necessary to replace a ceiling board damaged by mold or repair a corroded device.

Therefore, conventionally, attempts to prevent the thinning of the coating layer by increasing the contact width of the piping suspension band as much as possible are increasing.
Japanese Patent Laid-Open No. 2005-3014

  However, when the contact width of the piping suspension band is wide, for example, even when the width of the piping suspension band, which is usually 25 mm wide, is changed to about three times the 80 mm width, the coating layer after two weeks has a predetermined thickness. Experiments have shown that it can be reduced to half the thickness. In addition, this experiment is an experiment at normal temperature (20 to 26 degrees Celsius), and it is expected that the thickness reduction will be further increased when the refrigerant temperature is higher.

  If the pipe suspension band is further widened to prevent thinning, the necessary band width is about 100 to 250 mm, and the pipe suspension band becomes extremely large and bulky. As a result, there are inconveniences in transportation, storage, and workability, and there are many inconveniences in practical use, such as an extremely expensive piping suspending band and construction costs rising.

  Therefore, the present invention was created to solve the above-mentioned problems, and when supporting a coated copper pipe for a refrigerant provided with a coating layer made of a heat insulating coating material, the coating layer is prevented from being thinned.
