6063 aluminum pipe API 650 aluminum tanks

The mechanical seal of floating roof API 650 aluminum tanks relies on mechanical force to press the sealing steel plate tightly against the tank wall, so that it can slide on the tank wall and avoid gap as far as possible. However, mechanical seal has high requirements for the geometry of storage tank and poor adaptability, so mechanical seal is rarely used in newly built floating roof API 650 aluminum tanks.

Structural shapes of 9% and 5% nickel steel may be furnished to the chemical and physical requirements of ASTM A353, A553, or A645. Physical tests shall be in accordance with the requirements of ASTM A6.
API 650 aluminum tanks used Piping, Tubing, and Forgings
Material used for piping, tubing, and forgings shall be compatible in welding strength, and thermal expansion coefficient with the tank shell material. In addition to the specific requirements of this appendix, all piping within the limitations of 1.3.2 shall fulfill the minimum requirements of ASME B31.3.

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API 650 aluminum tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API 650 aluminum tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits.
