API Std 650 mechanically-anchored steel tanks roof venting

Welding of Large Steel storage tank Primary Components
a)Longitudinal and circumferential shell joints and joints that connect the API Std 650 mechanically-anchored steel tanks annular bottom plates together.
b)Joints that connect sections of compression rings and sections of shell stiffeners together. Backup bars may be used for these joints with complete penetration and complete fusion detail.
c)Joints around the periphery of a shell insert plate.
d)Joints that connect the shell to the bottom, unless a method of leak checking is used (see Q.8.2.1).Application scope of API 650 petroleum storage tank:
1. API Std 650 mechanically-anchored steel tanks Working pressure: atmospheric storage tank;
2. API 650 petroleum storage tank working temperature: -30℃～150℃;
3. API 650 petroleum storage tank liquid medium: various oil products, including naphtha, gasoline, diesel, kerosene, crude oil, fuel oil, heavy oil, benzene, xylene, methanol, ethanol;
4. API 650 petroleum storage tank volume: current design considerations generally do not exceed 10,000 cubic meters.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 Std 650 mechanically-anchored steel 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."The main advantages of the external floating roof API Std 650 mechanically-anchored steel tanks are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API Std 650 mechanically-anchored steel tanks, the production of external floating roof API Std 650 mechanically-anchored steel tanks is simple and the steel consumption is less. However, the central drainage system of external floating roof API Std 650 mechanically-anchored steel tanks should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.Both parties shall confirm the API Std 650 mechanically-anchored steel tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API Std 650 mechanically-anchored steel tanks steel plant.
