Field Erection of Large Vertical Steel Storage Tanks

1. Field Construction Overview

Large vertical storage tanks are typically constructed on site due to their size and weight.
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

Based on project conditions and tank size, we adopt proven field erection methods, including:

• Bottom plate and annular plate installation
• Shell erection using hydraulic jacking or step-by-step assembly
• Automatic and manual welding under controlled procedures
• Roof installation (fixed roof or floating roof systems)

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

3. Quality Control, Inspection, and Safety

All field construction activities are carried out under strict quality and safety management.

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

After construction completion, tanks undergo final inspection and testing according to project requirements.

This 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.
