A662 grade B plates API Std 650 mechanically-anchored steel tanks

Before pressure test, the main drain hose system of API 650 petroleum storage tank floating roof should be thoroughly flushed. Provide blind flanges, gaskets and bolts required for the API Std 650 mechanically-anchored steel tanks test (other types of covers are also required if necessary). Covers for maintenance shall be provided in accordance with the interfaces specified by API 650 petroleum storage tanks, and these seals shall remain in place after the test; and for those interfaces that are not provided for maintenance covers, the covers can be removed after the API Std 650 mechanically-anchored steel tanks test.

The cost of mechanical cleaning for vertical storage tank, API Std 650 mechanically-anchored steel tanks is low, almost all oil can be recovered, and the quality of recovered oil is high. The cost of manual cleaning for vertical storage tank, API Std 650 mechanically-anchored steel tanks is high, the oil can not be recovered completely, and the quality of recovered oil is low. The mechanical cleaning of API Std 650 mechanically-anchored steel tanks adopts fully enclosed operation, and separates oil, water and oil sand. There is no direct discharge of oily sewage and waste gas, which will not pollute the environment.

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 mechanically-anchored steel 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.

The shipping department of the company arranges shipping booking for customers' goods in advance, and makes good matching with inland transportation. Effectively manage and follow up the customer's shipping schedule and give feedback to customers in time. At the same time, the shipping department has a keen insight into the shipping market in different periods to reduce the transportation cost for the company and customers.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API Std 650 mechanically-anchored steel tanks steel materials can be shipped immediately after passing the quality inspection.
