Description

Technical Field

[0001] The utility model relates to the technical field of HVAC pipelines, in particular to a HVAC pipeline for a factory building. Background Art

[0002] The HVAC pipes in a factory are an important part of the HVAC system of a factory. They are mainly used to transport heated, cooled or ventilated air. During the use of the HVAC pipes, the HVAC pipes usually need to be insulated. The outer wall of the HVAC pipes needs to be wrapped with an insulation layer to reduce heat loss.

[0003] When wrapping the existing HVAC pipes with insulation layers, they are usually fixed by bundling, generally using galvanized iron wire, stainless steel wire or plastic cable ties. However, when fixing by bundling, the insulation layer needs to be wrapped around the HVAC pipe during the bundling process, and then fixed with the bundling wire or cable ties. In addition, the bundling needs to be performed evenly at a certain distance at multiple locations on the surface of the insulation layer. The process is relatively cumbersome and the construction process is relatively slow, which affects work efficiency. Therefore, a factory HVAC pipe is proposed to solve the above problems.
