API standard 650 carbon steel tank restrictions on joints

Welded steel API standard 650 carbon steel tank storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API standard 650 carbon steel tank all adopt on-site production and installation of storage tanks.

Tank cracks are common API standard 650 carbon steel tank defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API standard 650 carbon steel tank construction, which become obvious after the later use. Or in the process of using the API standard 650 carbon steel tank, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.

Pressure Setting of Safety DevicesExcept as provided in API 620 tank 9.5 for certain liquid relief valves, the pressure setting of a pressure-relieving device shall in no case exceed the maximum pressure that can exist at the level where the device is located when the pressure at the top of the tank equals the nominal pressure rating for the tank (see API 620 tank 5.3.1) and the liquid contained in the tank API standard 650 carbon steel tank is at the maximum design level.Vacuum-relieving devices shall be set to open at such a pressure or partial vacuum that the partial vacuum in the tank cannot exceed that for which the tank is designed when the inflow of air (or other gas or vapor) through the device is at its maximum specified rate.

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us API standard 650 carbon steel tank specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.

The company uses outsourced logistics operations. Our cooperated professional third-party logistics providers use the advantages of large-scale production and cost advantages to achieve cost savings by increasing the utilization of resources in each link, so that we can benefit from the separation of cost structure. Therefore, we can also provide customers with better, faster and more efficient cargo transportation, delivery, and lower freight costs.
