Product Description

Product Description

Large Scale Vertical Steel Storage Tank | AP 650 Standard Field-Erected Oil & Fuel Tank
Description:
Our large-scale vertical storage tanks are engineered for high-capacity liquid storage in oil depots, refineries, and chemical plants. Designed and manufactured in strict accordance with AP 650 or GB50341 standards, these tanks offer exceptional structural integrity and long-term reliability.
We specialize in Field-Erected Tanks, providing a complete solution from professional design and material pre-fabrication to on-site welding and inspection. For specialized mediums, we offer customized thermal insulation systems (as seen in the white-clad tanks) and high-performance internal anti-corrosion coatings.
Key Specifications:

• Volume: 100m³ - 50,000m³ (Large-scale customization).
• Material: High-quality Carbon Steel (Q235B/Q345R) or Stainless Steel.
• Structure: Vertical cylindrical, available with Fixed Roof (Cone/Dome) or Floating Roof.
• Insulation: Optional Rock wool/Glass wool insulation with Aluminum or Galvanized Steel cladding.
• Standards: AP 650, ASME, or Chinese GB standards.
• Application: Crude oil, Diesel, Fuel oil, Bitumen, Water, and Liquid Chemicals.

Product Highlights:

• Site-Specific Engineering: Tailored dimensions to maximize your facility's storage capacity and footprint.
• Advanced Welding Technology: Utilizing automatic girth welding machines to ensure X-ray quality welds and structural safety.
• Corrosion Protection: Professional sandblasting (Sa2.5) and multi-layer epoxy coating systems for harsh environments.

Turnkey Service: We provide experienced engineering teams for overseas or domestic on-site installation and commissioning.
