Steel plate and pipe materials for API 650 welded tanks for oil storage
Welded steel API 650 welded tanks for oil storage storage tanks that are designed, manufactured and installed on the ground are classified according to the API standard system. The three API standards API 650 welded tanks for oil storage all adopt on-site production and installation of storage tanks.
Allowable compressive stresses shall be in accordance with 5.5.4 except that for aluminum alloy plate the allowable compressive stresses shall be reduced by the ratio of the modulus of compressive elasticity to 29,000 for values of (t – c)/R less than 0.0175 and by the ratio of the minimum yield strength for the aluminum alloy in question to 30,000 for values of (t – c)/R equal to or greater than 0.0175 (see 5.5.2 for definitions). In all other equations in this standard API 650 welded tanks for oil storage where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
The lip seal of floating roof storage tank, API 650 welded tanks for oil storage relies on the sliding contact between elastic lip and tank wall. This kind of seal has strong applicability, but the requirements of manufacturing technology and material selection are high, and the determination of elastic seal also exists. The secondary seal of floating roof storage tank, API 650 welded tanks for oil storage is to add a seal on the basis of primary seal. It is proved by experiments that the secondary seal can reduce the liquid consumption by more than 50%, and has a more significant effect in safety.
