API 650 unanchored liquid-storage tanks NPS 8 sample hatch
This API 650 tank standard does not present orstablish a fixed series of allowable tank sizes: instead, it s intended to permit the purchaser to select whatever size API 650 unanchored liquid-storage tanks tank may best meet his needs.
When welding API 650 unanchored liquid-storage tanks, in order to avoid weld deformation, it is necessary to use corresponding welding process according to the type of steel used in the tank, such as welding requirements of steel plate, welding position, etc. Reasonable arrangement of the assembly sequence, the use of subsection back welding and jump welding method, strict control of welding process parameters, rigid fixation measures, take corrective measures for deformation compensation are necessary.
Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API 650 unanchored liquid-storage tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API 650 unanchored liquid-storage tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API 650 unanchored liquid-storage tanks steel transportation industry.
