Floating roofs 6 m (20 ft) in diameter API Std 650 closed top welded storage tanks

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 Std 650 closed top welded storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.Facilities for API 620 Storage Tanks InspectorThe manufacturer shall afford the inspector all reasonable facilities for testing and inspection and shall provide mutually agreeable advance notification to permit the examiner to witness all tests of the equipment and materials during fabrication, including all laboratory tests of the material to be used and all hydrostatic and pneumatic tests at the site of erection.The API Std 650 closed top welded storage tanks inspector shall be permitted free access to all parts of the plant concerned with the manufacture of the tank during fabrication and to all parts of the plants of material suppliers who are concerned with the manufacture of materials to be used in the tank.The floating roof is the top cover floating on the liquid level, so the sealing performance of API Std 650 closed top welded storage tanks API 650 oil storage tank is very important. The floating plate mainly adopts elastic packing, and at the same time, it is compressed with the wall of API 650 oil storage tank with pressure strip around, and fixed with the floating plate with bolts. After the API Std 650 closed top welded storage tanks floating plate is lowered to a certain position of about 1.8m, a prop will support the floating plate to keep it in position.On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life.

According to the technical standards, scientific and feasible process requirements are actually formulated. In the process of welding the edge plate of API Std 650 closed top welded storage tanks, electric welding is required on one side of the edge plate, so that the edge plate has a free shrinkage effect and greatly reduces the residual stress of the welding seam.
