Internal components of API 650 welded steel storage tanks

The thickness of the API 650 welded steel storage tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.
To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in.
(2.5)(0.375) + 0.75 = 1.69 in.Upon completion of construction, provide Purchaser with copies of Field Erected API 650 welded steel storage tanks Storage Tank Datasheets in accordance with Appendix L of API 650, which reflects the as-built conditions, certifying that the tank conforms with the requirements of this specification.In December of 2015, our regular India customer sent us an inquiry for API 650 welded steel storage tanks pipe. The inquiry requires no negative tolerance in both pipes’ outer diameter and pipe wall. After two weeks’ discussion, he put the order of 275 tons to us. The pipes are finished within just one month. Our customer come to our factory to inspect the quality and tolerance, all the products are well meet his demand. The pipes are arriving to Nhava Sheva port, customer is very happy with our products and service during the process.The preparatory work before the construction of the API 650 welded steel storage tanks is directly related to the quality assurance, project progress, construction safety and other aspects of the entire oil tank project. Therefore, the preparation work before the API 650 welded steel storage tanks construction should be paid attention to and planned. Before API 650 welded steel storage tanks construction, you need to prepare conventional machinery, materials, and facilities, as well as the quality control of the project, such as the installation method of the API 650 welded steel storage tanks, the welding method of the steel plate, and the inspection of the tank material. In addition, there is the most important item, construction safety protection.Over the years, the company has strived for perfection, being well-received.
