The construction of foundations for API standard 650 SUG III tanks

The preparatory work before the construction of the API standard 650 SUG III tanks is directly related to the quality assurance, project progress, construction safety and other aspects of the entire oil tank project. Therefore, the preparation work before the API standard 650 SUG III tanks construction should be paid attention to and planned. Before API standard 650 SUG III tanks construction, you need to prepare conventional machinery, materials, and facilities, as well as the quality control of the project, such as the installation method of the API standard 650 SUG III tanks, the welding method of the steel plate, and the inspection of the tank material. In addition, there is the most important item, construction safety protection.Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API standard 650 SUG III tanks plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API standard 650 SUG III tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.Management concept: abide by laws, regulations and social norms. To improve the system of management, to carry out activities with high corporate ethics. Mutual respect, unity and harmony, create a "fair, just and open" good working environment for employees. Forge ahead, constantly pursue new technology innovation, create social value, and become a sustainable growth enterprise.The automobile steel coil and sheets are one of our main steel materials exported to the overseas.
