5154 aluminum shapes API 650 special tank

Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API 650 special tank is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API 650 special tank Tanks must be above ground with a closed or open top.

The preparatory work before the construction of the API 650 special tank 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 650 special tank construction should be paid attention to and planned. Before API 650 special tank 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 650 special tank, 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.
