The Nanjing Engineering team successfully completed the welding of 9 spherical tanks at the Maoming Petrochemical tank farm
Thread Content
Recently, the Maoming Petrochemical Chemical Tank Farm project, constructed by Nanjing Engineering Company, has successfully completed the welding of the main structures for 9 spherical tanks, and has now entered the phase of installing process pipelines. The project includes a total of 5 light hydrocarbon spheres with a capacity of 3,000 cubic meters each, as well as 4 propylene spheres with a capacity of 3,000 cubic meters each, and adopts a welding method that relies primarily on automatic welding with manual welding used as a supplement. Light hydrocarbon spherical tanks utilize the automated spherical tank welding technology independently developed by Nanjing Engineering Company ； Propylene spheres are welded manually. The two welding processes were carried out simultaneously, which reduced labor intensity and operational risks while effectively shortening the construction period. During construction, the project team strictly followed the welding procedure specifications and implemented quality control throughout the entire process, resulting in a first-pass success rate of over 99% for the welding of all 9 spherical tanks.
