API standard 650 self-anchored flat-bottom steel tanks heat-affected zone

Compared with the fixed roof API 650 oil storage tank without API standard 650 self-anchored flat-bottom steel tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API standard 650 self-anchored flat-bottom steel tanks product and pollutes the environment.

API standard 650 self-anchored flat-bottom steel tanks Liquid Relief ValvesA tank, which is likely to operate completely filled with liquid, shall be equipped with one or more liquid relief valves at the top of the roof, unless otherwise protected against overpressure. When such valves are, in effect, supplementary relief devices, they may be set at a pressure not greater than 1.25 times the design pressure. Because the relief valve at the pump, which provides the inflow of liquid to the tank, is set at a pressure greater than 1.25 times the design pressure of any tank that may be built under these rules, provision should be made for preventing overfilling of the tank by a self-closing float valve, by some practicable pilot-valve control, or by any other proven device.

Anti corrosion of API standard 650 self-anchored flat-bottom steel tanks:
After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 self-anchored flat-bottom steel tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API standard 650 self-anchored flat-bottom steel tanks does not fall off and has good waterproof and rust resistance.
API standard 650 self-anchored flat-bottom steel tanks cleaning:
The long-term use of API standard 650 self-anchored flat-bottom steel tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API standard 650 self-anchored flat-bottom steel tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

Training is one of the important factors in the construction of corporate culture. Online training system can be used to enable all employees to take advantage of fragmented time and carry out targeted training anytime and anywhere without the limitation of time and region. Through training to improve work skills, at the same time, through training, let all improve their quality education level, let employees work around a goal, create a career, and produce results.
