API standard 650 flexible liquid storage tanks semiautomatic arc welding

API 650 storage tank is used for commonly used oil, gasoline, diesel, chemical and production water storage. API standard 650 flexible liquid storage tanks Storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 detailed standard specifies the design, processing, welding, inspection and installation procedures for storage tanks.

The main advantages of the external floating roof API standard 650 flexible liquid storage tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API standard 650 flexible liquid storage tanks, the production of external floating roof API standard 650 flexible liquid storage tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API standard 650 flexible liquid storage tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

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 standard 650 flexible liquid storage 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.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

Due to the surge in business volume in recent years. In addition to coordinating our own truck fleet, our logistics department has continuously developed high-quality logistics companies and signed long-term cooperation agreements. While enjoying the professional and fast service of logistics companies, we have significantly reduced transportation costs. That not only ensure our customers receive the goods at the same time, but also help them reduce shipping costs.
