API Std 650 carbon and low-alloy steel tanks shell support

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API Std 650 carbon and low-alloy steel tanks 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.

No matter what type of storage tank needs to be built, the natural conditions of the geographical area where the tank is located should be fully considered in the design. Because natural conditions will affect the service life, storage safety and construction cost of storage tanks such as API Std 650 carbon and low-alloy steel tanks. Generally, the natural conditions that need to be considered before API Std 650 carbon and low-alloy steel tanks design and construction are: regional temperature, wind load, snow load, ground endurance, external environment corrosion, etc.

Service Conditions and Hydrogen-induced Cracking
When the service conditions might include the presence of hydrogen sulfide or other conditions that may promote hydrogen-induced cracking effects, particularly near the bottom of the API Std 650 carbon and low-alloy steel tanks shell at the shell-to-bottom connections, care shall be taken to ensure that the materials and details of construction of the tank are adequate to resist hydrogen- induced cracking. The Purchaser shall consider restricting the sulphur content of the material to be stored through thickness testing of the steel, laboratory surveillance tests, and the use of internal tank coatings to reduce the possibility of hydrogen-induced cracking.

Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the API Std 650 carbon and low-alloy steel tanks project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of API Std 650 carbon and low-alloy steel tanks customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
