Steel plate and pipe materials for API Std 650 ground supported liquid storage tanks
Deformation of the welding seam of the API Std 650 ground supported liquid storage tanks is a common quality problem during the actual use of the API Std 650 ground supported liquid storage tanks, which easily causes the tank body to leak and affects the safety of the oil storage tank. The welding seam deformation of the API Std 650 ground supported liquid storage tanks is mainly caused by the lack of reserved welding seam gap and irregular operation. The oil storage tank has not reserved the corresponding weld gap, resulting in deeper root removal during the front welding activity. The heat output of the weld will increase under the influence of a long time, and the deformation of the weld will gradually become serious.
Manufacturer’s Report and CertificateUpon completion of all tests and inspections on each tank API Std 650 ground supported liquid 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.
This standard applies only to API 650 tank API Std 650 ground supported liquid storage tanks whose entire bottom is uniformly supported and to API 650 tank in non-refrigerated service that have a maximum design temperature of 93°C (200 °F) or less.
