Introduction:In 2022, a certain petrochemical company launched a new special black public relations project in the polymerization department to fill the gap in the domestic market for a certain special polyester material. The prefabrication and installation of two color paste storage tanks (T151A/B) are the control engineering of this project. Due to their large size (ф 4900 * 14475 * 10mm 304), they need to be prefabricated into tube sections for on-site assembly; ② The roughness of the inner surface (Ra0.8) is relatively high. Becoming one of the difficulties in the construction, installation, and quality control of this project. To better control construction quality in construction projects, quality control should be carried out from the following five aspects.
Keywords : group welding; Segmented prefabrication; On site assembly; verticality; Ellipticity; Quality Control
