FABRICATION AND INSTALLATION OF INDUSTRIAL PETROLEUM STORAGE TANKS

Manufacturing Petroleum Storage Tanks to International Safety Standards

In petrochemical plants or transit depots, petroleum storage tanks are an exceptionally high-risk storage category. Even a minor deviation during fabrication can lead to severe safety consequences. Newtech provides turnkey tank fabrication and installation services, committing to eliminating all operational risks through rigorous technical control procedures.

Design Standards and Material Selection

• Stringent Design Benchmarks: All of Newtech’s tank manufacturing technical drawings are established based on the API 650 standard (American Petroleum Institute) for welded steel tanks operating at low pressure, alongside TCVN standards for fire safety.

• High-Strength Steel Materials: We exclusively utilize specialized carbon steel or stainless steel plates (depending on the fluid medium), complete with full traceability and Mill Test Certificates (MTC) to guarantee stress tolerance and chemical corrosion resistance.

Fabrication Techniques and Welding Procedures (WPS)

The structural durability of a storage tank depends 90% on the quality of its welds. Newtech applies advanced welding methods (FCAW, SAW, GTAW) executed by highly skilled welders holding international 6G certifications. The Welding Procedure Specification (WPS) is meticulously calculated regarding current, voltage, and interpass temperatures to ensure flawless weld penetration.

Non-Destructive Testing (NDT) Quality Control

Prior to hydrostatic testing, 100% of critical butt welds must pass severe NDT inspections:

• Radiographic Testing (RT) and Ultrasonic Testing (UT) to screen for internal cracks and volumetric flaws.

• Penetrant Testing (PT) and Magnetic Particle Testing (MT) to evaluate the absolute integrity of the material's surface.
