Uplift on FoundationFor API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.
When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.
When the day light gradually decreases, the temperature of oil in the BV EH32 floating vessel steel will also decrease, the evaporation speed will gradually slow down, and the pressure in the BV EH32 floating vessel steel will also decrease. When the pressure in the BV EH32 floating vessel steel is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the BV EH32 floating vessel steel through the open vacuum valve, which is the "suction" process of the oil tank.
Aspire to technological innovation and pursue first-class quality steel BV EH32 floating vessel steel products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.
