Preparation work before floating roof tank construction

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel floating roof tank storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s floating roof tank domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.

For the welding of floating roof tank bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the floating roof tank. The welding sequence of the central plate is from the center of the central plate to the surrounding.
