6063 aluminum tube API 650 larger diameter 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 larger diameter tanks where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.
Fabricated to API standard 650 Welded Tanks for Oil Storage Shop Assembled API 650 larger diameter tanks storage tanks, these tanks are commonly used at oil and natural gas terminals, API 650 larger diameter tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.
In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe API 650 larger diameter tanks for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
}Prefabrication requirements of API 650 larger diameter tanks, large vertical storage tank wall panels:1. The prefabrication of wall panel shall be processed in strict accordance with the requirements of the drawings, and inspection records shall be made.2. After the wall panel is rolled, it should be placed on the platform for inspection with a template. In the vertical direction, use a straight-line template to check, the gap should not be greater than 2 mm, and in the horizontal direction, use an arc-shaped template to check, and the interval should not be greater than 4 mm.3. When wall panels are rounded, attention should be paid to prevent irreversible plastic deformation caused by external forces. After rolling, it should be placed on the platform for inspection, and then placed on the prepared mold.
