API 650 petroleum storage tanks formulas

Prevent the storage liquid from impacting the inner wall of the API 650 petroleum storage tank or increase the internal pressure, reduce the corrosion of the tank top and the tank wall, and extend the service life of the API 650 petroleum storage tanks storage tank.

The normal operation of API 650 petroleum storage tanks includes receiving oil, storing oil, sending oil and measuring oil. The correct use and operation of oil storage tank is directly related to the production safety and oil loss of oil tank. In order to use and operate the API 650 petroleum storage tanks correctly, it is necessary to be familiar with and master the structure and performance of the API 650 petroleum storage tanks and its accessories, such as the maximum storage capacity of the oil tank, the pressure range that can bear and the safety fabrication specification.

Impact Test Requirements for Oil Storage Tanks Primary Components
All API 650 petroleum storage tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

The business department is mainly responsible for communicating with customers, from the manufacturing of steel plates, steel pipes and other products, knowing customers' needs and processing conditions, etc. within the time agreed with customers, the delivery time is short, the price is the most competitive, and the service is the best. Their responsibilities are to deal with customer consultation, solve customer problems, update production plans, and instruct the logistics department to deliver products to customers.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API 650 petroleum storage tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
