hy Is the Production Process So Critical?

The fusion between steel and glass coating is the cornerstone of Glass-Fused-to-Steel Tanks. It directly impacts the tank’s durability, corrosion resistance, and service life. By adhering to rigorous production standards, we ensure that every tank we produce meets the highest international quality requirements.

Our Step-by-Step Production Process

CNC Laser Cutting

Confirmed drawings are input into the computer, and bolt holes and openings are precisely cut using CNC laser cutting machines.

Ensures accuracy and consistency in every panel.

Steel Pre-treatment – Shot Blasting

Steel panels undergo shot blasting according to SSPC SP10 standards, achieving a silver-white surface free of impurities.

Prepares the steel surface for optimal enamel adhesion.

Arch Bending

Steel panels are arch bent to the required radian based on the tank diameter.

Ensures the structural integrity and proper fit of the panels during assembly.

Automatic Enamel Spraying

Glass coating is automatically sprayed onto both sides of the steel panels.

Coating thickness is controlled within 230 to 450 microns for optimal protection and durability.

High Temperature Tunnel Oven

Enameled panels are fired in a tunnel oven at temperatures ranging from 820℃ to 930℃.

Facilitates the interfacial fusion of steel and glass, ensuring a strong and seamless bond.

Product Inspection

Each panel undergoes comprehensive quality inspection, including coating thickness measurement, 1500V holiday test, and color consistency check.

Ensures zero discontinuities and uniform quality across all products.
