Material Features
1. Base Material: Premium Q235B carbon steel, offering high tensile strength, good weldability, and load-bearing capacity to withstand high-pressure storage scenarios.
2. Anti-Corrosion Coating: Multi-layer epoxy resin or polyethylene coating applied to both interior and exterior surfaces, forming a seamless barrier against acids, alkalis, salts, and moisture. The coating is non-toxic, environmentally friendly, and compliant with food-grade standards for applicable uses.
3. Reinforcement Components: Galvanized steel brackets and anti-slip steel ladders, enhancing structural stability and operational safety without compromising corrosion resistance.

Craftsmanship Technology
1. Precision Cutting & Welding: CNC plasma cutting ensures accurate dimensioning, while submerged arc welding delivers smooth, high-strength weld seams that pass ultrasonic flaw detection.
2. Surface Preparation: Shot blasting treatment removes rust and impurities from the steel surface, achieving a Sa2.5 grade finish to maximize coating adhesion.
3. Coating Application: Automated electrostatic spraying ensures uniform coating coverage, followed by high-temperature curing to enhance coating hardness and corrosion resistance.
4. Leakage Testing: 100% water pressure testing and air tightness testing are conducted to guarantee zero leakage.
