API 650 mechanically-anchored tanks welder

All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API 650 mechanically-anchored tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.

Compared with the external floating roof API 650 mechanically-anchored tanks, the internal floating roof API 650 mechanically-anchored tanks has the advantages of protecting the floating roof from wind and rain and ensuring the quality of liquid storage under the floating roof. At the same time, because the inner floating plate is in the tank, there is no rain and snow load, so the central drainage pipe and escalator and other accessories on the floating plate can be omitted. In addition, under the same sealing conditions, the internal floating roof tank can further reduce the evaporation loss compared with the External floating roof tank.

Manufacturer’s Report and CertificateUpon completion of all tests and inspections on each tank API 650 mechanically-anchored 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.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API 650 mechanically-anchored tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
