SI units API Std 650 carbon steel storage tanks
The preparatory work before the construction of the API Std 650 carbon steel storage tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API Std 650 carbon steel storage tanks:Before API Std 650 carbon steel storage tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.
The insert plate weld shall not cross any shell seams and shall be at least the greater of 10 times the shell thickness or 12 in. from any other weld in the API Std 650 carbon steel storage tanks shell including shell seams, shell-to-bottom weld or attachment welds. The butt weld around the periphery of the plate shall be examined over 100% of its length by both liquid penetrant method and radiographic method. The liquid penetrant examination is required on the root pass, on the back-gouged surface, and on the inside and outside finished weld surfaces. Additionally, the weld shall be vacuum box leak tested.
API 650 is an American standard for welding flat bottom vertical storage tanks. This API Std 650 carbon steel storage tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API Std 650 carbon steel storage tanks crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.
