Pipeline prefabrication: conduct pipeline design, prefabrication management, pipeline cutting, pipeline groove processing, welding, logistics, anti-corrosion paint, pipeline flaw detection, etc. in a fixed area.

Advantages of pipeline prefabrication: it is convenient to coordinate and control the quality, progress and management in a fixed area, and reduce the workload of on-site prefabrication and on-site installation. In this way, the quality of prefabricated welded junction can also be guaranteed, the installation efficiency can be improved, the overall cost will also be reduced, and it is easier to manage, which greatly improves the installation, quality and progress of the whole project.
