Welded API Std 650 unanchored flat-bottom tank

As an experienced world class steel materials supplier and exporter, logistics and fast delivery is a crucial step to us. Our logistics department and shipping department take the responsiblity to allocate and transport steel materials from our mill and warehouse to customer port or designated destination. The cooperation of the two departemts are excellent and that powerfully support our fast delivery, and strive for shorter time for customers to receive steel materials.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 Std 650 unanchored flat-bottom tank where yield strength or modulus of elasticity is used, such as Equations 27 and 28, similar corrections shall be made for aluminum alloys.API 650 internal floating roof oil tank is a volatile liquid storage tank with a combination of a dome tank and an internal floating roof structure, which is a floating roof assembled under the dome of the API Std 650 unanchored flat-bottom tank storage tank. The combination of the vault roof outside the API 650 storage tank and the floating roof inside the tank has been widely used in gasoline, aviation kerosene and more volatile chemical liquids.Team concept: respect, communication, coordination and symbiosisBusiness philosophy: leading by strategy, driving by innovation, creating valueManagement concept: goal oriented, efficient operation, stimulation of vitality and continuous improvementQuality concept: standard guidance, control process, craftsman spirit, leading serviceTalent concept: lifelong learning, give full scope to the talents, the sea refuses no riverInnovation concept: innovation is the first driving force for the company's high-quality developmentCustomer concept: taking customers as the center is the foundation of the company's survival and developmentAtmospheric API Std 650 unanchored flat-bottom tank refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API Std 650 unanchored flat-bottom tank usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.
