Prefabricated overhead soft heat preservation pipe system, manufacturing method and transportation and installation method

Abstract

The invention discloses a prefabricated overhead soft heat preservation pipe system, a manufacturing method and a transportation and installation method. The prefabricated overhead soft heat preservation pipe system comprises a plurality of working pipes, composite heat preservation and insulation layers, outer protection layers and vertical heat insulation pipe supports. The working pipes are coaxially connected in a welded mode, the vertical heat insulation pipe supports are installed on the corresponding working pipes, the composite heat preservation and insulation layers wrap the corresponding portions of the working pipes and the corresponding portions of the vertical heat insulation pipe supports, and the outer protection layers wrap the corresponding portions of the composite heat preservation and insulation layers and the corresponding portions of the vertical heat insulation pipe supports. Compared with traditional on-site manufacturing, factory prefabrication does not generate waste materials, pipelines can be completely utilized, no stub bars exist, heat preservation materials are not wasted, the heat preservation materials are basically free of loss, the on-site installation and construction speed is high, the construction period is short, the workload of on-site nondestructive testing is reduced, comprehensive energy consumption is reduced, the energy utilization rate is improved, transportation and installation are convenient, and soft heat preservation pipes are not prone to damage.

Description

technical field [0001] The invention belongs to the technical field of steam pipeline construction, and in particular relates to a prefabricated overhead soft thermal insulation pipe system, a manufacturing method, and a transportation and installation method. Background technique [0002] In the process of heat pipe network engineering design, the traditional overhead pipes of the heat network use the construction site for insulation. This construction method has the following problems: [0003] 1. Most of the overhead pipes are located outdoors, and the insulation construction is seriously affected by the weather. [0004] 2. Insulation materials occupy a large area, are susceptible to moisture, moths, are not easy to store, increase management costs, have a lot of insulation waste, and waste the site seriously. If the excess insulation materials are transported to other sites or back to the company's warehouse, it will take time and effort and increase costs. [0005] 3...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the overhead pipes are located outdoors, and the insulation construction is seriously affected by the weather

[0004] 2. Insulation materials occupy a large area, are susceptible to moisture, moths, are not easy to store, increase management costs, have a lot of insulation waste, and waste the site seriously

If the excess insulation materials are transported to other sites or back to the company's warehouse, it will take time and effort and increase the cost

[0005] 3. The on-site construction time is long, and the construction quality is difficult to guarantee

[0006] 4. On-site NDT workload is heavy

[0007] 5. Soft thermal insulation materials are usually pressed and seamed to wrap the working pipeline. If it runs for a long time, it is easy to produce gaps and affect the thermal insulation effect

The outer sheath is generally connected by rivets, and there will be gaps. In rainy and snowy weather, the gaps are prone to water seepage, resulting in failure of internal insulation and shortening the life of prefabricated overhead pipes.
