Description

Technical Field

[0001] The utility model relates to the technical field of oil and natural gas pipelines, in particular to a heat preservation device for oil and natural gas pipelines. Background Art

[0002] Oil and gas pipelines refer to specialized pipeline systems used to transport oil and natural gas. These pipelines are typically buried underground or cross waterways, forming a complex network used to transport oil and natural gas from production sites to processing plants, storage facilities, or end users. The construction and maintenance of these pipeline systems are strictly regulated to ensure the safe and efficient transportation of these important energy resources. To improve the safety of oil and gas transportation, insulation devices need to be installed on the pipelines. Existing insulation devices for oil and gas pipelines have certain drawbacks when used. The insulation pipe is placed over the working pipe for insulation. During installation, the pipe surface needs to be cut with a cutter, the insulation pipe is placed on the pipe, and glue is applied to the two cut surfaces of the cut insulation pipe. When sealing the pipe, the two ends of the joint are pressed tightly together and sealed from both ends to the middle. However, due to the effects of thermal expansion and contraction, cracks are easily formed on the cut surface, resulting in poor insulation effect. In addition, the insulation pipe needs to be destroyed during installation and removal, which wastes resources and is cumbersome. To this end, we propose an insulation device for oil and gas pipelines. Utility Model Content
