API standard 650 stainless and carbon steel tank supported cone roofs

While GB50341 generally takes the weld coefficient as 0.9;When the minimum yield strength of API standard 650 stainless and carbon steel tank steel plate is greater than 390 MPa, take 0.85. The thickness of API 650 tanks is generally smaller than that of GB50341, and this difference is particularly evident in the design of large tanks, where the overall weight of the tanks varies greatly.

Anti corrosion of API standard 650 stainless and carbon steel tank:
After using for a certain period of time, it is necessary to check the corrosion protection of the API standard 650 stainless and carbon steel tank. 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 stainless and carbon steel tank does not fall off and has good waterproof and rust resistance.
API standard 650 stainless and carbon steel tank cleaning:
The long-term use of API standard 650 stainless and carbon steel tank 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 stainless and carbon steel tank shall be cleaned and derusted regularly to ensure the quality of oil stored and the safety of oil tank equipment.

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API standard 650 stainless and carbon steel tank roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

The company has the industry's advanced automated production lines and precision laboratory instruments and a capable steel industry management team. Through scientific management, optimized technology, and rigorous testing, the company will keep the production efficiency and production quality at the leading level in the industry and continue to provide customers with high-quality API standard 650 stainless and carbon steel tank products. At the same time, the company is committed to building a comprehensive steel manufacturing industry and strives to make the company leads new progress and development.

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.
