API 5L grade A pipe API 650 unanchored tanks

The water dissolved in the oil will be separated out from the oil stored in the API 650 unanchored tanks for a long time, and the acidic water layer will appear at the bottom of the API 650 unanchored tanks for a long time, which will accelerate the corrosion of the API 650 unanchored tanks and cause the wall thinning and even leakage. With the increase of service life, the API 650 unanchored tanks must be inspected and cleaned regularly to check the hidden danger.The impact tests for API 620 welded storage tanks used pipe (including structural members made of pipe), bolting, and forgings, shall be in accordance with ASTM specifications ASTM A333 (seamless only) pipe, ASTM A36 Mod 1 plate, ASTM A131 Grades CS, D, and E steel plate, ASTM A633 Grade A CSA G40.21 Grades 38WT, 44WT and 50WT high-strength low-alloy structural steel plate, ASTM A350 carbon and low alloy steel forgings, and ASTM A320 Grade L7 bolts.API 650 is the standard for welded tanks for oil storage. It specifies the API 650 unanchored tanks design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI.Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, API 650 unanchored tanks and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
