Self-supporting umbrella roof API standard 650 partially anchored liquid-storage tanks
Except as permitted by API standard 620 Q.8.6, the test shall be conducted after the entire tank is complete, before the insulation is applied. Except as limited by foundation or stress conditions, the test shall consist of filling the tank with water to the design liquid level and applying an overload air pressure of 1.25 times the pressure for which the vapor space is designed. The load on the supporting foundation shall preferably not exceed the established allowable bearing value for the tank site. Where a thorough evaluation of the foundation justifies a temporary increase, the established allowable bearing may be increased for the test condition, but the increase shall be not more than 25%.
BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API standard 650 partially anchored liquid-storage tanks oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.
We cooperated with the Peruvian government for many years. And supply them large diameter steel pipes and pipe fittings to support their Hydropower Station Projects. We do 100% UT, RT, Hydraulic test and so on tests for the API standard 650 partially anchored liquid-storage tanks steel pipes. And do PT, MT and so on tests for the pipe fittings. We published "Welding Procedure Qualification report" after production. And our mill will keep the test record in the documentary department for 5 years. If meet any problems in following application, we can check the test record easily and assist to solve problems at the first time.
}Anti corrosion of API standard 650 partially anchored liquid-storage tanks:After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 partially anchored liquid-storage tanks. If necessary, the outer wall of the metal oil tank should be painted with new anti-corrosion paint to ensure that the outer wall of the API standard 650 partially anchored liquid-storage tanks does not fall off and has good waterproof and rust resistance.API standard 650 partially anchored liquid-storage tanks cleaning:The long-term use of API standard 650 partially anchored liquid-storage tanks will produce impurities on the tank wall and deposit on the tank bottom, resulting in tank corrosion to leakage. According to the safety standard of oil tank, the API standard 650 partially anchored liquid-storage tanks shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.
