Description

Technical Field

[0002] As we all know, insulated pipes are widely used in liquid and gas transportation pipelines. In the insulated transportation pipelines, pipe insulation is a very important link. The success or failure of this link is directly related to whether the pipeline can be officially put into use. The existing technology usually uses tape to fix the insulation sleeve on the pipe, but when the pipe is outdoors, the tape is easily caused by environmental factors such as rain and light, resulting in low viscosity, thereby affecting the stability of the insulation sleeve when used on the outdoor pipe. In addition, the rainproof performance of the insulation sleeve in the existing technology when used outdoors needs to be improved, which is not conducive to extending the service life of the insulation layer on the outdoor pipe. For this reason, we propose a multi-layer composite pipe insulation layer. Utility Model Content
