ASTM A131 structural shapes API 650 cylindrical tanks
API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 cylindrical tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 cylindrical tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
Oil storage tank is an important equipment commonly used in petroleum and petrochemical industry. New API 650 cylindrical tanks, metal storage tank must be tested before it can be put into use or put into storage. The common inspection methods of API 650 cylindrical tanks include radiographic testing, ultrasonic testing, magnetic particle testing and dye penetrant testing. The parts and operation requirements of these testing methods are different, so they should be selected according to the required characteristics.
Any joints between the adjacent sections of API 620 oil storage tank stiffening rings, as shown in Figure Q-1, shall be made so that the required moment of inertia of the combined ring-shell section is provided. Weld joints between adjacent sections shall be made with full-thickness and full-penetration butt-welds. Stiffening-ring butt-welds may employ metal backing strips. Backing strips and the associated welding shall be made in a manner that provides a smooth contour in the rat hole and all other weld joint ends. All weld passes shall be started at the rat hole and other weld joint ends and shall be completed by moving away from these ends. Passes shall be overlapped away from edges to provide a smooth continuous weld.
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 cylindrical tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API 650 cylindrical tanks steel materials can be shipped immediately after passing the quality inspection.
