I. Core Technology: Seamless Spiral Extrusion Winding
1. Fully Automated Winding and Forming
TYIC NEW ENERGY adopts spiral extrusion winding technology imported from Europe. PPH granules are thermally melted into a paste-like strip via extruders, then spirally overlaid and wound onto a rotating mold. The multiple layers are fused into one continuous body.
- Seamless Structure: The tank body is free of horizontal weld seams, completely eliminating leakage risks common with traditional panel welding. Overall structural strength is increased by more than 30%.
- Precision Thickness Control: The tank adopts a gradient structure with “thinner top and thicker bottom,” designed based on stress distribution. This not only optimizes material use but also enhances pressure resistance.
2. Automated Welding Process
- Large-Scale Extrusion Welding: The tank bottom is connected to the tank body using automatic extrusion welding, forming a large single-pass V-groove weld (60×60mm) with a melt depth of 1.5–2mm and a welding coefficient ≥ 0.9, approaching the strength of the base material.
- Integrated Nozzle Welding: Pipe nozzles are welded using German MUNSCH handheld welding machines, resulting in smooth, burr-free weld seams.
II. Material and Performance Advantages
1. High-Purity Raw Materials and Consistency Guarantee
TYIC NEW ENERGY uses flame-retardant grade PPH raw materials (2150) from LyondellBasell in Europe. Sheet and welding rods are produced from the same source to ensure material purity, meeting corrosion resistance requirements for electronic-grade vanadium/iron-chromium electrolytes.
Alternatively, the more cost-effective Yanshan 4220 PPH raw material can be used based on customer needs.
The sheets include UV absorbers and anti-aging additives, extending service life up to 30 years under conditions ranging from -20℃ to 100℃.
2. Outstanding Physical and Chemical Performance
| Performance Index | TYIC NEW ENERGY PPH Performance |
|---|---|
| Corrosion Resistance | Resists strong acids (HCl, dilute H₂SO₄), strong alkalis, and salts (except strong oxidants like concentrated nitric acid) |
| Creep Resistance | High long-term hydrostatic strength, prevents deformation |
| Low-Temperature Impact | β-crystalline modified PPH maintains toughness at -20℃ |
III. Production and Quality Assurance System
1. Fully Automated Equipment Line
TYIC NEW ENERGY utilizes imported spiral winding units (5–8 times more efficient than manual), CNC bending machines, and panel joining machines to reduce human error.
Real-time quality monitoring includes spark leak detectors, ultrasonic thickness gauges, and universal testing machines to ensure zero-defect deliveries.
2. Certifications and Compliance
- Certified under ISO 9001, EN 12573 (European thermoplastic container standard), and HG 20640 (Chinese industry standard).
- Licensed for hazardous chemical packaging production, suitable for high-risk scenarios such as nuclear power and energy storage.
IV. Application Effectiveness and Industry Validation
1. Large-Scale Project Fulfillment Capability
TYIC NEW ENERGY has delivered multiple successful PPH tank projects for high-demand industrial clients (case studies available upon request).
2. Comparative Advantage Over Traditional Methods
| Criteria | TYIC NEW ENERGY PPH TANK | Traditional Welded Tanks |
| Tank Structure | Seamless spiral winding | Multi-panel welding with reinforcement rings |
| Leakage Risk | Near zero | Prone to corrosion at weld seams |
| Production Efficiency | High (automated continuous forming) | Low (mainly manual welding) |
| Service Life | 30 years (with anti-aging additives) | 10–15 years |
| Cost-Effectiveness | Low long-term maintenance costs | Frequent repairs lead to hidden costs |
Summary
TYIC NEW ENERGY’s spiral-wound PPH tanks deliver durability, chemical resistance, and lifecycle efficiency for the toughest industrial conditions.
