A537 Cl 1 plates API 650 self-anchored flat-bottom steel tanks

API 650 is the standard for welded tanks for oil storage. It specifies the API 650 self-anchored flat-bottom steel 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.

In the actual welding of API 650 self-anchored flat-bottom steel tanks, operators will use more arc-shaped plates for tailor-welding to better adapt to the larger volume of oil storage tanks. In order to effectively control the deformation of the welding seam of the API 650 self-anchored flat-bottom steel tanks, a scientific and accurate prefabricated bottom plate is required. In the process of prefabricating the bottom plate of the oil storage tank, it is necessary to strictly follow the technical requirements for the construction of the oil storage tank. At the same time, it is also necessary to clarify the external dimensions according to its actual manufacturing standards so that it has sufficient shrinkage.

Hydrostatic Test
The API 650 self-anchored flat-bottom steel tanks product shall be vented to the atmosphere when it is filled with or emptied of water. During water filling, the elevations of at least four equidistant points at the bottom of the tank shell and on top of the ringwall or slab shall be checked. Differential settlement, or uniform settlement of substantial magnitude, requires an immediate stop to water filling. Any further filling with water will depend on an evaluation of the measured settlement.

The mode of iron and API 650 self-anchored flat-bottom steel tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 self-anchored flat-bottom steel tanks steel logistics.
