A573 Gr 65 plates API Std 650 self-anchored flat-bottom tanks

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, API Std 650 self-anchored flat-bottom tanks and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The most popular standards for API Std 650 self-anchored flat-bottom tanks are API Std 650, JIS B8501, BS2654, GB50341, etc. The formulas used in each standard are derived from the hoop stress calculation formula of membrane theory. Combined with the stress characteristics of API Std 650 self-anchored flat-bottom tanks, plus the allowable stress, weld coefficient and additional wall thickness, the wall thickness calculation formula is complete. The allowable stress and weld coefficient are determined according to the material performance characteristics and construction technology level of each country. According to different API Std 650 self-anchored flat-bottom tanks standards, the calculation results of tank wall thickness are sometimes quite different.

Data Required from Manufacturer on Completed TanksIf specified in the purchase order, the Manufacturer shall supply marked copies of plans (or a separate sketch) showing the location of all plates, with a means of identifying each plate with the heat numbers. These markings shall be checked by the inspector. A copy shall be attached to the Manufacturer’s report.Check of Stress-relieving OperationThe API Std 650 self-anchored flat-bottom tanks inspector shall check any thermal stress-relieving operation and shall be satisfied that the temperature readings are accurate and that the procedure conforms to the applicable requirements of these rules.
