Shandong Daming Completes Batch Delivery of 65 Atmospheric Tanks

Recently, Shandong Daming successfully completed the fabrication and delivery of 65 customized atmospheric tanks featuring sandwich structures. The project required consistent production quality, strict dimensional control, and efficient batch manufacturing to meet the customer’s delivery requirements.

As high-precision fabricated components, these tanks involved demanding requirements for structural accuracy, welding quality, and sealing performance. To ensure stable production and timely delivery, Shandong Daming established a coordinated manufacturing system involving project planning, production, engineering, quality inspection, and other teams. Through detailed scheduling and close collaboration, the company achieved efficient coordination between production planning, shop-floor execution, and quality control.

To improve production efficiency and maintain consistency across the batch, the project team developed a streamlined manufacturing workflow covering material cutting, edge preparation, plate rolling, assembly, composite welding, and water filling tests. During welding operations, different welding approaches were applied based on the structural characteristics and sealing requirements of each weld joint, ensuring reliable forming quality, structural strength, and production efficiency.

During the fabrication process, the team encountered challenges in producing short tank sections that could not be processed through conventional equipment setups. To address this issue, Shandong Daming developed a customized manufacturing solution by optimizing process routes, improving tooling arrangements, and refining operating procedures. These measures enabled stable production and ensured that each tank met the required technical specifications.

Throughout the entire manufacturing cycle, strict quality inspections were implemented across every key process. Critical parameters including dimensional accuracy, weld quality, and sealing performance were continuously monitored, while key operations such as composite welding and precision fit-up were carefully controlled to reduce risks related to welding deformation, leakage, and dimensional deviation.

The successful completion of this project reflects Shandong Daming’s ability to organize complex batch production, optimize fabrication processes, and maintain consistent quality standards for customized tank projects. The experience gained from this delivery further strengthens the company’s expertise in non-standard tank fabrication and integrated manufacturing services.
