CSA G40.21 Gr 350WT plates API standard 650 ground supported flat-bottom tanks

Bearing on Foundations
Foundations shall preferably be designed to resist the load exerted by the API Standard 620 tank and its contents when the tank is filled with water to the design liquid level. Foundations shall be designed at least for the maximum operating conditions including the wind load. During the API standard 650 ground supported flat-bottom tanks water test, the total load on the foundation shall not exceed 125% of the allowable loading. If necessary, the water level during the test may be reduced below the design liquid level line so as not to exceed the 25% maximum overload (see Q.8.1.2).According to API Standard 650, the stairs used for API 650 petroleum storage tanks or thermal insulation tanks should be double longitudinal beams supported by a minimum of ribs. If the gap between the API standard 650 ground supported flat-bottom tanks tank shell and the stringer of the API 650 petroleum storage tank exceeds 200mm, handrails should be provided on both sides of the stairs. Unless otherwise specified, according to API standard 650 ground supported flat-bottom tanks ASTM A123, the following accessories shall be hot-dip galvanized. The damaged zinc coating should be repaired with zinc alloy.Shipping 1000MT low alloy steel plate and cutting sectors to Mexico in 2014. Andritz is One Of Biggest company In globe world. Our company Win The Tender With Lauca project In Mexico To Offer 1000MT Steel Plate API standard 650 ground supported flat-bottom tanks to them.The Steel plate need to do cutting according the drawing by standard tolerance,UT,MT and dimension request.After Get Customer Contract, Steel Plate Are Produced within 40 days .Then, Goods Trucked To Shanghai Loading Port Soon And Shipping In Time To Statisfy With Project Expected After Finished Producing. The Steel Quality Had Been Get Customers’Praise."Generally, the building area temperature of the API standard 650 ground supported flat-bottom tanks should be considered before the tank design and construction. The temperature in the API standard 650 ground supported flat-bottom tanks building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the API standard 650 ground supported flat-bottom tanks, the higher the corresponding pressure and the more volatile loss.Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
