API 650 mixed material tanks spectral acceleration coefficients
API 650 petroleum storage tank body design is mainly the design of tank bottom, API 650 mixed material tanks tank top and tank wall, and the design of tank wall is particularly important. As the main pressure bearing part of API 650 petroleum storage tank, the tank wall bears loads including liquid pressure, wind pressure, seismic load, opening stress, etc. The calculation of such loads is explained in detail in various API 650 mixed material tanks storage tank design standards. But in addition, the API 650 petroleum storage tank wall also bears the push-pull force and torque of the connected pipeline.
The design metal temperature of API 650 mixed material tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.
The cleanliness of the API 650 mixed material tanks has a great influence on the safety of the tank and the quality of the oil stored. Keeping the API 650 mixed material tanks clean can slow down the corrosion of the tank wall and reduce the pollution to the oil. If the inside of the API 650 mixed material tanks is not cleaned all the year round, a lot of rust and metal impurities will be produced in the tank. These impurities will cause the oil to slowly oxidize and deteriorate. The impurities mixed into the oil will also block the filter and oil circuit, causing oil supply failure.
Management concept: abide by laws, regulations and social norms. To improve the system of management, to carry out activities with high corporate ethics. Mutual respect, unity and harmony, create a "fair, just and open" good working environment for employees. Forge ahead, constantly pursue new technology innovation, create social value, and become a sustainable growth enterprise.
The company attaches great importance to logistics services, sets up our own transport truck fleet, improves customer response capacity through the improvement of logistics capacity, and further reduces costs. Customers ordering API 650 mixed material tanks steel from our company can not only enjoy the service of fast delivery, but also enjoy lower transportation costs. Fast, accurate, simple and efficient has always been our principle.
The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
