9m diameter API 650 welded steel storage tanks
Tanks which are designed following rules and guidelines of API 650 are API 650 tanks. API 650 API 650 welded steel storage tanks is the governing code for Welded tanks for Oil storage normally operating in the atmospheric pressure range. The code API 650 provides guidelines for design, fabrication, material, erection, and inspection of welded vertical and cylindrical storage tanks. Such API 650 welded steel storage tanks Tanks must be above ground with a closed or open top.
To scientifically evaluate the remaining service life of the API 650 welded steel storage 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 welded steel storage tanks, etc. factors to judge. Because the metal characteristics, corrosion defects, load and other numerical parameters of the API 650 welded steel storage tanks are randomly changed, the value of the remaining service life of the storage tank will also be dynamic.
When the API 650 welded steel storage tanks top shell course is the minimum thickness indicated in 5.10.4, Table 5-6 and Figure 5-6, details a – e, h and i, the minimum anchorage shall be designed for normal loads as specified by the Purchaser and by this standard. See 5.11.2.3 for the allowable stress. When the top shell course is thickened beyond the minimum thickness provided in Table 5-6 or as in Figure 5-6, details f and g, or a knuckle is used, the minimum anchorage shall be designed for three times the internal design pressure. The allowable stress for this loading is 90% of the minimum specified yield strength of anchorage material.
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 welded steel storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
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 welded steel storage 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.
