It is understood that the underground pipe network project of Weifang’s 300,000-ton/year high-end polypropylene project requires the installation of 14,000-inch pipes, which is faced with many unfavorable factors such as complex geological conditions, frequent heavy rainfall in summer, and harsh construction conditions
During the construction, the participating employees are faced with the simultaneous construction of civil engineering and underground pipe network, and cross-operations between various disciplines are frequent
As of June 22, the underground pipeline network project of the project has completed 93% of the total construction, and the first-time flaw detection pass rate of underground pipeline welding has reached 98.
