Cylindrical Industrial Vertical Welded Steel Tank Above Ground for Oil Storage

Product Specification

Vertical Welded Steel Tank for Various Oil Storage Applications

Product Description

Steel welded storage tanks is primarily constructed from high-quality steel utilizing advanced welding technology. The tank body typically adopts a cylindrical design, which facilitates the uniform distribution of internal pressure and external loads. This steel material exhibits high strength and excellent toughness, enabling it to withstand substantial weights and pressures. The following outlines key aspects regarding steel welded storage tanks:

• Construction Specifications: The construction of Vertical Welded Steel Tank for Various Oil Storage Applications must adhere to the "Construction Specifications for Vertical Cylindrical Steel Welded Storage Tanks" API-650 or GB 50128-2014, which delineates technical requirements spanning material inspection, prefabrication, assembly, welding, inspection, and acceptance across various stages.
• Material Inspection: The materials and accessories utilized in the construction of the tank must possess quality certification and adhere to the relevant specifications outlined in the design documents. Steel plates and accessories should feature clear product identification markings. Welding materials, including welding rods, wires, fluxes, and protective gases, are also required to have quality certification and comply with applicable national standards.
• Pre-fabrication: The pre-fabrication methods employed for the tank must not compromise the integrity of the parent material or diminish its performance. The pre-fabrication of tank wall plates, bottom plates, and floating roofs should conform to specific dimensional and geometric requirements to ensure accuracy during assembly as well as structural stability.
• Assembly: Prior to the assembly of the tank wall, it is essential to verify the geometric dimensions of the prefabricated panels to ensure compliance with specified requirements. Only after they are confirmed as qualified can assembly proceed. During this process, careful attention must be given to the vertical alignment of the panels, the gap between butt joints, and tolerances for misalignment.
• Welding: Welding represents a critical phase in tank construction and must be executed by certified welders in accordance with approved welding procedure specifications. Detailed regulations govern the selection of welding materials, welding sequence, as well as weld repair and rework procedures.
• Inspection and Acceptance: Upon completion of the tank construction, a comprehensive inspection and acceptance process is required, encompassing visual inspections of welds, nondestructive testing, and assessments of the tank's geometric shape and dimensions to ensure its quality and safety.
• Safety and Quality: During the construction phase of the tank, strict compliance with relevant safety regulations and quality standards must be maintained to safeguard the well-being of construction personnel as well as ensure the reliability of tank operations.

Main Technical Parameter
