ASTM A350 forgings API 650 ground supported flat-bottom tanks
Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API 650 ground supported flat-bottom tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.
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 650 ground supported flat-bottom 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.
To scientifically evaluate the remaining service life of the API 650 ground supported flat-bottom tanks, it is necessary to know the thickness change and development trend of the storage tank sheet after long-term use, combined with the metal characteristics of the storage tank, the influence of various external conditions and the continuous change of the oil pressure in the API 650 ground supported flat-bottom tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 ground supported flat-bottom tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
Safety production is the cornerstone of enterprise survival and development. The company established a safety management network, which achieved clear powers and responsibilities, clear responsibilities, effective management and control, and provided organizational guarantee for safe production. The company strictly complies with the "Environmental Protection Law", establishes an effective environmental protection emission control system and waste gas, waste water, waste solid recycling system, and makes great efforts to harden, lighten, green, and beautify the plant, and strive to build green steel enterprises.
In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API 650 ground supported flat-bottom tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
