ASTM A350 forgings API 650 self-anchored flat-bottom tanks

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 650 self-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 650 self-anchored flat-bottom tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.

Volatilization is the characteristic of oil. Under normal temperature and pressure, as long as the oil is in contact with air, the surface will volatilize. Through scientific analysis and summary, the causes of oil volatilization loss in API 650 self-anchored flat-bottom tanks are: natural ventilation loss, static storage loss, dynamic liquid level loss. In the use of API 650 self-anchored flat-bottom tanks, static storage loss and dynamic liquid level loss are common losses.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API 650 self-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.
