9m diameter API standard 650 self-anchored flat-bottom steel tanks

API standard 650 self-anchored flat-bottom steel tanks Oil measuring hole: The oil measuring hole is used to measure the height, temperature and sampling of the oil stored in the tank, and is installed near the tank top platform. API standard 650 self-anchored flat-bottom steel tanks Fire extinguisher: The fire extinguisher (also known as the flame arrestor) of the oil tank is composed of a fire box, a copper wire mesh and an aluminum partition. It is installed under the breathing valve or safety valve to prevent sparks and air from entering the inside of the tank through the breathing valve or safety valve and causing accidents.

Proof Tests for Establishing Allowable Working PressuresBecause pressures in liquid storage tanks built according to these rules vary quite markedly from the tops to the bottoms of the tanks, proof testing of these tanks presents problems not usually encountered in the construction of unfired pressure vessels–especially where the API standard 650 self-anchored flat-bottom steel tanks parts under investigation are located near the bottoms of the tanks. The principal difficulty is devising a test or series of tests that will reliably establish the working pressure that can be permitted on the part of the unproven design without, at the same time, imposing hazardous conditions on other parts located at higher levels in the tank.

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API standard 650 self-anchored flat-bottom steel tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.
