6061 aluminum tube API 650 floating-roof tanks

The thickness of the API 650 floating-roof tanks wall plate, t, required by 5.10.3 for the latitudinal unit forces, T2, acting at this level is 0.57 in. The nozzle neck is seamless steel pipe and conforms to ASTM A53, Grade A; the materials in the tank wall and reinforcing pad conform to ASTM A442 Grade 55. The main joints in the tank walls are fully radiographed, double-welded butt joints. The adequacy of the reinforcement and attachment welds shown in Figure F-7 shall be determined.
To determine the length of the nozzle neck within the limits of reinforcement, the smaller of the following calculated values shall be used:(2.5)(0.625) = 1.56 in.
(2.5)(0.375) + 0.75 = 1.69 in.

When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the API 650 floating-roof tanks tank wall thickness is not considered in the tank wall design.

The Peru customer has cooperated with us since April 2015, and then they purchased 300 tons A36 mild steel plates as trial order. Since then, they book more than 1000 tons from us every time, and about two times every year. They asked SGS test every time. Through our cooperation those years, we have built very good relationship and they entrust us to buy other related API 650 floating-roof tanks products for them from China also. And they have introduced us good customers in Peru, among which there are also governmental projects. It is a win-win cooperation between us.

The preparatory work before the construction of the API 650 floating-roof tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API 650 floating-roof tanks:
Before API 650 floating-roof tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality API 650 floating-roof tanks products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
