API standard 650 aboveground steel oil storage tanks anchorage

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 aboveground steel oil storage tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.

API 650 is constructed from carbon steel, austenitic duplex stainless steel, and API standard 650 aboveground steel oil storage tanks aluminium A Welding Certification is stipulated by American Society of Mechanical Engineers (ASME), Section 10. There is a required inspection, no third party. The inspection cost is the cost of the NDE.

In 2016, we brought our customer to visit our NM400 hot rolled plate; producing line and our shanghai warehouse for 30,000 tons plate and structure. As a result, Our client purchased 500 tons NM400 as first order, which is shipped by 3 times. In future. Our company will always guarantee that all the delivery condition for Hardox plate API standard 650 aboveground steel oil storage tanks provided will be with quenching and tempering, which is the best delivery type according GB/T 24186 standard.

Oil tank is often used to store crude oil, diesel oil, gasoline and other oil. The main structure of API standard 650 aboveground steel oil storage tanks is composed of tank top, tank wall, tank bottom and accessories. The API standard 650 aboveground steel oil storage tanks should be inspected after the completion of construction, and the detection methods of different structure positions are different. Tank wall inspection: for the newly built oil tank, water filling test shall be conducted to check whether the tank wall is tight, and the appearance inspection shall be conducted for the tank wall plate and weld. Tank wall thickness detection: the oil tank wall thickness is mainly detected by ultrasonic wave, with high efficiency.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
