Engineering for Strength and Site Flexibility
The defining characteristic of this 1,000-ton tank is its heavy-gauge steel shell, engineered to manage the hydrostatic pressure of full containment.
- Heavy-Duty Wall Construction: We fabricate the tank using Q235B carbon steel plates with a substantial 12mm wall thickness. This is significantly thicker than standard atmospheric tanks, providing exceptional resistance to structural stress and external impacts. This robust shell forms the backbone of a system designed for a service life exceeding 20 years.
- Advanced Corrosion Barrier: Given the long-term exposure to sulfur compounds in crude oil and atmospheric moisture, internal protection is paramount. We apply a three-layer epoxy anti-rust coating following a thorough sandblasting pretreatment. This creates a chemically bonded barrier that prevents oxidation and pitting, which are the primary causes of tank failure.
- Modular Design for Challenging Sites: The 12-meter diameter and 10.5-meter height are optimized for stability. More importantly, the tank is designed in segmented modules. This allows us to ship components to sites with narrow access roads or weight-restricted bridges, where a fully assembled tank would be impossible to deliver.

Precision Manufacturing & Field Assembly
Our process adheres strictly to API 650 and ISO 9001 standards, focusing on weld quality and coating integrity:
- Precision Segmentation: Steel plates are CNC-cut and rolled into precise segments, designed for field or shop welding.
- High-Strength Welding: Skilled technicians perform submerged arc welding (SAW) to create full-penetration, seamless joints that are stronger than the parent metal.
- Surface Preparation: Prior to coating, the surface is sandblasted to Sa 2.5 standard to ensure maximum adhesion of the epoxy layers.
- Validation Testing: The completed assembly undergoes hydraulic pressure testing and air tightness checks to guarantee zero leakage risks before handover.
