Fixed roof API 650 self-anchored flat-bottom tanks

The American standard API 650 design has been widely used. We can use our existing professional design knowledge to serve the construction projects of large API 650 self-anchored flat-bottom tanks storage tanks, oil tanks and water tanks. The company is a small and medium enterprise that can provide American standard API 650 design software, design qualifications, and design capabilities.

API 650 self-anchored flat-bottom tanks, Oil tank is a large-scale storage equipment used to store oil materials. Usually, the service life of API 650 self-anchored flat-bottom tanks is related to the actual working conditions. The design service life of most oil tanks is 20 years, and some of them are 10-15 years. Generally, none of them is less than 10 years. However, the design service life of API 650 self-anchored flat-bottom tanks is on the one hand, which is an ideal state, but there are many objective factors in the actual process, it is impossible to achieve the designed service life. How to effectively increase the service life of API 650 self-anchored flat-bottom tanks?

In this project, an elemental area of API 620 oil storage tank wall is constructed of ASTM A516 Grade 55 steel plate subjected to a meridional unit force, T1, of 2620 lbf/in. tension and a latitudinal unit force, T2, of 2880 lbf/in. compression. The meridional radius of curvature, R1, is 132 in., and the length of the normal from the surface to the axis of revolution, R2, is 409 in. The joints in the wall are spot-radiographed, double-welded butt joints, and no corrosion allowance is required.
The problem in this example is to graphically find the minimum thickness of tank wall required for the given conditions (see API 620 tank standard 5.10.3.3).
Solution: As determined from Table 5-1, the maximum, allowable tensile stress value, Sts, for ASTM A516 Grade 55 steel plate in simple tension is 16,500 lbf/in.2. Since the compressive stress is latitudinal, the governing value of R for this situation is R1, or 132 in.

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API 650 self-anchored flat-bottom tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

The company's logistics adopts the method of cooperation with logistics companies. As a third-party logistics company is engaged in the operation of multiple logistics projects, it can integrate various logistics resources, making the logistics operation cost relatively low and the logistics operations more efficient. Thus we can provide more professional logistics services, while also focusing on our core business of steel materials.
