Precision Storage Tank - Construction On Site

1. Field Construction Overview

Large vertical storage tanks are characterized by their massive size and unique structural design, and are constructed entirely on-site. Scientific construction planning, precise execution of processes, and rigorous quality inspections are key to ensuring the structural integrity of the tanks, meeting project standards, and maintaining a controllable construction schedule.

Field erection requires precise coordination between engineering, equipment, welding, and inspection to ensure structural safety and construction efficiency.

We provide complete on-site construction solutions for large vertical steel storage tanks, covering oil, chemical, water, and industrial applications.

Safe, controlled, and standard-compliant construction is the foundation of every successful storage tank project.

2. On-Site Construction Method and Process

Taking into account the site conditions, storage tank specifications, and operational requirements, we employ proven, standardized on-site construction methods, ensuring standardized procedures throughout the entire process and advancing the work in a step-by-step, orderly manner. The core construction phases include:

• Re-leveling of the foundation to establish a solid construction reference.
• Laying and Welding of the Tank Bottom Plate and Annular Steel Plates.
• Hydraulic Jacking and Segmented Assembly for Tank Wall Construction.
• Combining Automatic Welding with Manual Touch-up Welding to Ensure Weld Quality.
• On-site Installation of Fixed and Floating Roofs as Required
• Weld Inspection and Grinding to Eliminate Construction Hazards.
• Comprehensive Rust Removal and Anti-Corrosion Treatment to Enhance Protective Performance.
• Comprehensive Pressure Testing and Acceptance to Ensure Project Compliance.

Construction sequences are carefully planned to minimize deformation and ensure dimensional accuracy.

3. Quality Control, Inspection, and Safety

The entire process of the storage tank construction is carried out on-site, relying on standardized quality management and safety management systems. The entire process is supervised and the details are strictly controlled. Multiple dimensions such as process, safety and quality are comprehensively checked layer by layer.

Our on-site control includes:

• Compliance with approved construction procedures
• Continuous welding inspection and non-destructive testing
• Dimensional checks during each construction stage
• Safety management and risk control on site

Every critical stage is inspected to meet applicable design codes and standards.

4. Commissioning and Project Handover

Once the installation and construction of the storage tanks are fully completed, the acceptance inspection phase begins. In accordance with the project’s customized standards, inspections are conducted item by item to thoroughly identify potential hidden issues, ensuring that all specifications meet the required standards and that the tanks are ready for safe commissioning and operation.

These includes:

• Visual and dimensional inspection
• Leakage testing and functional checks
• Documentation and quality records submission

The project is formally handed over only after meeting all technical and safety requirements.
