66m diameter API 650 special tank

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API 650 special 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.

Design of Compression-ring Regions
In this project, a cylindrical tank 30 ft in diameter is designed for an internal pressure of 5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade A steel for thicknesses of 1/2 in. and less. The top course of the butt- welded cylindrical sidewall is 1/4 in. thick, including a 1/16 in. corrosion allowance. The tank API 650 special tank roof is a butt-welded spherical dome with an internal radius of 30 ft and a thickness of 1/4 in., including a 1/16 in. corrosion allowance. The maximum design liquid level is 6 in. below the plane of the juncture of the roof and sidewall.

In order to prevent the deformation of the bottom of metal vertical storage tank, API 650 special tank during welding, the number of welders should be reasonably distributed. When welding metal vertical API 650 special tank, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.

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.

Accept the inquiry from the owner of the goods and the inquiry by sea: master the port and price from the port of shipment to all continents and routes, and the port and price that the owner often needs to serve; the shipping schedule information of the main shipping companies; when necessary, ask the owner of the inquiry for some category information, such as the name of the goods, the level of danger, etc. (water hazard code).

The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API 650 special tank principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
