API standard 650 mechanically-anchored flat-bottom tanks overturning moment

Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API standard 650 mechanically-anchored flat-bottom tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.

After using for a certain period of time, it is necessary to check the corrosion protection of the metal oil tank and paint the outer wall of the API standard 650 mechanically-anchored flat-bottom tanks with anti-corrosion paint. The inlet and outlet valves of API standard 650 mechanically-anchored flat-bottom tanks shall be inspected and maintained regularly to ensure they are in good condition. Oil tank will produce a lot of dirt when it is stored for a long time. Usually, the cleaning cycle of metal oil tank is about three to five years.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API standard 650 mechanically-anchored flat-bottom 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.

Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API standard 650 mechanically-anchored flat-bottom tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API standard 650 mechanically-anchored flat-bottom tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

The company's logistics team adheres to the development concept of “gathering advantages, providing superior services, creating value, and leading the market”, and tightly focuses on the strategic positioning of “developing large-scale steel logistics and building large-scale steel supermarkets”. Facing the whole country and integrating into the world to build an "one center, one network" international circulation system. Through the development of 5-10 years, it is expected to form a modern steel industry with annual operating income exceeding 2.5 billion yuan.
