Material requirements for API 650 flat-bottom oil storage tanks

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API 650 flat-bottom oil storage tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API 650 flat-bottom oil storage tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.Manufacturer’s Report and CertificateUpon completion of all tests and inspections on each tank API 650 flat-bottom oil storage tanks, the Manufacturer shall prepare a report summarizing all the data on the tank, including foundations (if they are within the Manufacturer’s scope of responsibility) and shall attach to the report all drawings and charts as required by other paragraphs in this section of the rules (see API 620 tank 7.13 and Appendix M).The tank Manufacturer shall furnish and fill out a certificate for each tank (such as that shown in Appendix M), attesting that the tank has been constructed according to the rules in this standard. This certificate shall be signed by the Manufacturer and the Purchaser’s inspector. This certificate, together with the nameplate or markings placed on the tank, shall guarantee that the Manufacturer has complied with all applicable requirements of these rules.According to API 650 tanks, anchoring devices should be designed to transfer overturning moments to the API 650 flat-bottom oil storage tanks tank foundation. At the same time, according to API 650 tank Appendix F, when the tank is to be anchored, the size of the anchoring parts is determined by the maximum lifting force caused by the internal pressure and wind load or the combination of internal pressure and seismic load.Customer concept: customer first. Guided by market changes and guided by customer needs, we design the optimal product solutions and provide the best after-sales service. Partners: to reach a balance of interests with all stakeholders, to build a harmonious coexistence and win-win cooperation.The most popular standards for API 650 flat-bottom oil storage 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 650 flat-bottom oil storage 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 650 flat-bottom oil storage tanks standards, the calculation results of tank wall thickness are sometimes quite different.
