The main body of Zhejiang high-pressure polyethylene pipeline installation of the ten construction company is completed

Since entering August, the construction of the high-pressure polyethylene device of the second phase of Zhejiang Petrochemical Project undertaken by the Tenth Construction Company of Refining and Chemical Engineering has been carried out efficiently.
With the hard work of the participating employees, the most difficult construction and the highest quality process have been required.
The pipeline installation successfully achieved the main completion goal
.

It is understood that the total installed process pipeline of the high-pressure polyethylene plant of the second phase of the Zhejiang Petrochemical Project is 600,000 inches in diameter, including 750 pipeline pressure test packages, which is one of the key lines for the entire project
.
Since the start of the high-pressure polyethylene plant, the second-phase project department of Zhejiang Petrochemical Corporation of Ten Construction has accelerated the progress of professional construction such as underground pipe network, civil concrete pouring, steel structure, equipment, etc.

The project department takes "management innovation and improvement of work efficiency" as the project construction orientation, continuously improves and optimizes the process pipeline construction organization plan, and relies on the advantages of the pipeline processing plant to implement the construction strategy of centralized cutting, unified prefabrication, and automatic welding for the process pipeline to improve the process.
Ergonomics of pipeline construction
.
According to statistics, in the entire process pipeline construction, automatic welding of 150,000-inch diameter pipeline welds has been realized, laying a solid foundation for accelerating the process of process pipeline construction

In response to the strict welding quality requirements of the process pipelines of the high-pressure polyethylene device, the project department started from the source and carried out 100% inspections on the process pipelines and welding materials entering the construction site to prevent unqualified materials from flowing into the construction line
.
The project department strictly controls the construction quality of process pipelines, conducts a comprehensive inspection of common welding quality defects such as cracks, slag inclusions, and pores, and strives to improve pipeline welding quality by increasing welder training and organizing welding skills competitions

At present, the project department took the opportunity of the completion of the main body of the process pipeline installation to quickly set off a peak of pipeline pressure test.
