A573 grade 400 plates API 650 flexible liquid storage tanks
API was established in 1919. It is the first national-level business association in the United States. It is one of the earliest and most successful chambers of commerce in the world to formulate standards. An important task of API API 650 flexible liquid storage tanks is to be responsible for API 650 oil storage tanks and natural gas. Standardization of industrial equipment to ensure the safety, reliability and interchangeability of equipment used in the industry.
In this project, an area of tank wall is constructed of ASTM A285, Grade C, steel plate that is 5/8-in. thick and has spot-radiographed, double-welded butt joints. The wall is subject to tension in a meridional direction and to compression in a latitudinal direction. The values of R1 and R2 at the point under consideration are 75 in. and 300 in. respectively. A corrosion allowance of 1/16 in. is required. The computed (meridional) tensile stress, stc, in the net thickness after deduction of the corrosion allowance is 6000 lbf/in.2. The problem in this example is to find the maximum allowable (latitudinal) compressive stress value for the given conditions, in conformance with the provisions of API 620 tank standard 5.5.4.5.
Generally, the building area temperature of the API 650 flexible liquid storage tanks should be considered before the tank design and construction. The temperature in the API 650 flexible liquid storage tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API 650 flexible liquid storage tanks, the higher the corresponding pressure and the more volatile loss.
The work concept attaches importance to talents, creates a high-income and high-standard employment mode and work mode, actively advocates all kinds of talents to inspire each other, respect each other, unite and act together, cultivates employees' corporate interests above all else, is tolerant and enterprising, learns correct ways of doing things, improves employees' Professional quality, encourages and urges employees to make continuous progress, Continuously realize self value and grow together with the enterprise.
In the process of API 650 flexible liquid storage tanks steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API 650 flexible liquid storage tanks different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent API 650 flexible liquid storage tanks products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the API 650 flexible liquid storage tanks technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
