API standard 650 welded storage tanks bottom plates

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API standard 650 welded storage tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.

The engineering quality of API standard 650 welded storage tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API standard 650 welded storage tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API standard 650 welded storage tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

The API standard 650 welded storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us

The main competitive means adopted by major domestic ports are to expand ports, build deep-water berths and channels, improve service quality to reduce the comprehensive cost of customers, and at the same time, to improve competitive advantage, we should also take appropriate measures to reduce relevant costs and prices.
