ASTM A737 plates API 650 duplex stainless steel tanks
In API 650 oil storage tank, when the mixing ratio of combustible medium and air reaches a certain limit, it is easy to cause explosion. Therefore, it is necessary to add API 650 duplex stainless steel tanks external floating roof to open cylindrical steel API 650 duplex stainless steel tanks tank. At present, the external floating roof is most suitable for large-scale API 650 oil storage tank in China, ranging from 20000, 30000, 50000 cubic meters to 100000 cubic meters.
As we know, the vertical metal tank, API 650 duplex stainless steel tanks is welded by many components, and the welding quality of each component determines the later use effect of the API 650 duplex stainless steel tanks. Professional API 650 duplex stainless steel tanks manufacturers should have a set of professional skills in the welding process of API 650 duplex stainless steel tanks. Key points for weld inspection of vertical metal tank, API 650 duplex stainless steel tanks: 1. It is strictly forbidden to paint the welds before passing the inspection. 2. Visual inspection shall be carried out for welds. 3. NDT shall be carried out on the weld.
When the API 650 duplex stainless steel 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.
