API 650 Tank

API 650 Tank Steel Plates are specialized steel plates used in the construction of large, above-ground storage tanks (ASTs) designed to store petroleum, chemicals, water, and other liquids. These tanks are built according to the American Petroleum Institute (API) 650 standard, which ensures structural integrity, corrosion resistance, and safety in demanding storage environments.

Hera-Trade offers high-grade API 650-compliant steel plates that meet the precise thickness, strength, and corrosion resistance required for storage tank construction. These plates are commonly used in the oil & gas, chemical, and water storage industries, where safety and durability are of utmost importance. Our API 650 plates support the construction of both flat-bottom and floating-roof tank designs.

Pressure Levels: API 620 tanks may withstand pressures as high as 15 psi (103 kPa), but API 650 tanks are made for tanks with internal pressures no greater than 2.5 psi (17 kPa). Because of this distinction, API 620 tanks can hold liquids that need confinement at a slightly greater pressure.

Design specifications: API 650 tanks must meet strict specifications for the material, thickness, welding, and inspection of the tank’s roof, bottom, and shell. Although the specifications for API 620 tanks are comparable, they are more demanding because of the increased pressure capacities, necessitating extra design factors including more thorough testing and analysis.

Tank Shape: While API 620 tanks can be either rectangular or cylindrical in shape, API 650 tanks are usually cylindrical.

Applications:

• Petroleum Storage Tanks: Used in refineries and fuel distribution terminals.
• Chemical Storage Tanks: For safe storage of hazardous chemicals and acids.
• Water Storage Tanks: Municipal water tanks, irrigation tanks, and emergency water reserves.
• Firefighting Water Tanks: Used in commercial and industrial buildings.

Technical Advantages:

• Compliance with API 650 Standards: Ensures tanks meet global safety and quality standards.
• Corrosion Resistance: Withstands exposure to corrosive liquids and harsh environmental conditions.
• High Yield Strength: Provides superior load-bearing capacity for large-capacity tanks.
• Weldability and Formability: Allows for easy fabrication of flat-bottom or floating-roof tank structures.
• Versatile Thickness Options: Available in various thicknesses to suit tank size and liquid type.

By choosing Hera-Trade’s API 650 tank steel plates, businesses can ensure the safe and long-term storage of essential liquids like petroleum, chemicals, and water. Our plates offer the strength and reliability required for large-capacity, above-ground tanks used in critical industries.
