50ft diameter API Std 650 tanks

The inner and outer tanks may be decoupled for seismic design of the tank and anchorage and assumed to act independently. However, if the inner and outer tanks API Std 650 tanks are supported by a common foundation, the seismic foundation loading shall be calculated using the lesser response modification values for either the inner tank or outer tank for both tanks and a dynamic analysis shall be performed to determine the combined effect.
Allowable Stresses: For Appendix R tanks, design allowable stresses shall be per API 620 large low pressure storage tank, Section R.3.3.Before pressure testing, thoroughly flush the API 650 tank floating roof primary drain hose system. Supply API Std 650 tanks blind flanges, gaskets, and bolting (for other types of blanking covers as may be required) necessary for testing.In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month’s negotiation and quotation, they chose us as there supplier of raw steel plate API Std 650 tanks grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.The bottom plate of the vertical API Std 650 tanks directly contacts with the foundation soil, which is suitable for the flexible foundation, and its settlement characteristics are quite different from that of the rigid foundation. For the settlement calculation of the foundation of a vertical API Std 650 tanks, the one-way compression layered sum method can be used. The calculation method is to divide the foundation soil into several layers of compression within the calculation depth of the foundation settlement, and then find the sum. The calculation method of the compression amount of each layer is the same as the calculation method of the compression amount under the condition of no lateral deformation.The company's after-sales service tenet is "customer first, timely guarantee, enthusiastic service and effective work". In order to establish a set of perfect after-sales service system and strict management system, so that the after-sales service can be effectively guaranteed. The company has set up after-sales service department to ensure timely, unique and effective response to every user's request, coordinate internal resources internally, and put an end to all evasion and delay.
