Fabrication of API 650 mechanically-anchored tanks

The horizontal projection of the roof plate within the compression-ring region is 4.9 x 0.866 = 4.25 in., which fulfills the requirement of API 620 tank standard 5.12.5.1. The required area and horizontal projection can be provided by any of the standard angles listed in Table F-3.
Any of these angles may be used in accordance with the details of Figure 5-6, detail a or b, but if details c, h, or i in Figure 5-6 were intended, the net area of the angle must be calculated by deducting the area expected to be lost by corrosion from that part of the angle surface that is exposed to the interior of the tank.BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API 650 mechanically-anchored tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.In November of 2015, Thailand one company contacted with us from Internet. They are find the trustable supplier of S355J2H seamless pipe API 650 mechanically-anchored tanks for there cable car supporter. Due to the special using of the pipes, they are very careful and servious when choosing the supplier. After one months contact and discussion by email, they come to our company. We drive to the pipe mill for visit of 2 days. Through this visit, they are very confident with our production ability and proucts quality. Finally, they accept the grade we suggest Q345D. After back to office, they put the order of 1400 tons pipe to us directly.Anti corrosion of API 650 mechanically-anchored tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API 650 mechanically-anchored tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API 650 mechanically-anchored tanks does not fall off and has good waterproof and rust resistance.
API 650 mechanically-anchored tanks cleaning:
The long-term use of API 650 mechanically-anchored tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API 650 mechanically-anchored tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel API 650 mechanically-anchored tanks products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
