API Std 650 SUG II tanks designed to operate under vacuum conditions
storage tanks API Std 650 SUG II tanks designed in accordance with the rules and guidelines of API 650 are called API 650 storage tanks. API 650 is a control rule for welded storage tanks that work normally in the normal pressure range.
The specifications used in the design of large oil tanks, API Std 650 SUG II tanks mainly include American Petroleum Institute Standard API 650, Japanese Industrial Standard JIS B8501, British Industrial Standard BS2654 and Chinese National Standard GB50341 from a global perspective. The formulas used in each specification are based on the hoop stress in the membrane theory. Each specification is based on the performance characteristics of materials and the construction technology level of their respective countries to determine the allowable stresses and weld coefficients. Therefore, the calculation results of tank wall thickness of API Std 650 SUG II tanks with the same volume are sometimes quite different according to different specifications.

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
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.
