API620 crude oil storage tanks manufacturers metal temperature during hydrostatic testing

Except as permitted by API standard 620 Q.8.6, the test shall be conducted after the entire tank is complete, before the insulation is applied. Except as limited by foundation or stress conditions, the test shall consist of filling the tank with water to the design liquid level and applying an overload air pressure of 1.25 times the pressure for which the vapor space is designed. The load on the supporting foundation shall preferably not exceed the established allowable bearing value for the tank site. Where a thorough evaluation of the foundation justifies a temporary increase, the established allowable bearing may be increased for the test condition, but the increase shall be not more than 25%.

When welding API620 crude oil storage tanks manufacturers, 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.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and API620 crude oil storage tanks manufacturers produced water. Advance Tank has extensive experience with API 650 tanks ranging in diameter from 8' - 300' for refineries, terminals, pipeline facilities and other clients.
